Although the beauty counseling method described in Patent Document 1 described above can accurately determine the skin condition of the subject, it is not easy to use because it requires the use of special optical equipment. The same applies to a beauty counseling method in which a face-to-face interview is performed by a beauty specialist.

In addition, the beauty determination method described in Patent Document 2 has a problem that the determination result does not necessarily become what the subject desires, that is, does not represent the state assumed by the subject. In the first place, whether to worry about various skin cases such as acne and dirt on pores is a problem including a very subjective state for each subject. For example, among multiple subjects with similar (similar) degrees of both sebum excess factor and skin dryness factor, some subjects suffer from excess sebum, other subjects suffer from skin dryness, and Other subjects are both worried about excessive sebum and dry skin. On the other hand, in the method of Patent Document 2, a uniform determination result is presented to a plurality of subjects who have a common sebum excess factor and a skin drying factor. For this reason, when cosmetic counseling is performed based on such a determination result, a method for dealing with skin cases unrelated to the subject's troubles is exclusively proposed, and the subject's sufficient satisfaction may not be obtained.

On the other hand, according to the present invention, it is possible to determine the skin condition, which is the degree of occurrence of skin trouble, which is considered important for the subject, by a simple method and present a judgment result with a high degree of satisfaction of the subject.

In the present invention, a plurality of skin factors representing skin cases are associated with each of a plurality of state parameters representing skin characteristics such as sebum amount and water retention amount. Since the skin condition of the subject is determined from various aspects based on these many skin factors, an objectively accurate determination result can be obtained. Furthermore, in the present invention, a high weight is given to the attention factor score indicating the degree of expression of the skin case related to some skin factors (attention factor), and the general factor score indicating the degree of expression of the skin case related to other general factors A state parameter is calculated by assigning a low weight to. For this reason, the determination result which emphasized the skin case with a strong subject's subjective trouble is presented.

According to the present invention, the subject's skin condition can be easily determined by the subject inputting a score indicating the degree of expression of the skin case. In addition, a determination result is presented that is objectively accurate and conforms to the subject's subjective skin problems.

The skin condition determination apparatus of the present invention can read a computer program and execute a corresponding processing operation, so that a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an I / F (Interface) ) Hardware constructed by general-purpose devices such as units, dedicated logic circuits constructed to execute predetermined processing operations, combinations thereof, and the like. The various constituent elements of the present invention only have to be formed so as to realize the function. For example, dedicated hardware that exhibits a predetermined function, data processing in which a predetermined function is given by a computer program It can be realized as an apparatus, a predetermined function realized in the data processing apparatus by a computer program, an arbitrary combination thereof, or the like. The various constituent elements of the present invention do not have to be independent of each other, one constituent element is a part of another constituent element, a part of one constituent element and another constituent element. It is allowed to have some overlap.

Storing data by the component (storage unit) of the present invention means that the apparatus of the present invention has a function of storing data, and it is not always necessary that the data is always stored.

Further, in describing the skin condition determination method of the present invention, a plurality of steps are described in order, but the order of description does not limit the order or timing of executing the plurality of steps. For this reason, when carrying out the skin condition determination method of the present invention, the order of the plurality of steps can be changed within a range that does not hinder the contents, and some or all of the execution timings of the plurality of steps are mutually connected. It may be duplicated.

<Skin condition judgment method>
FIG. 2 is a flowchart of a skin condition determination method (present method) according to an embodiment of the present invention. FIG. 3 is a diagram showing a parameter table TP showing a list of state parameters P. FIG. 4 is a diagram showing a skin factor table TF showing a list of skin factors F. The parameter table TP and the skin factor table TF are stored in the skin factor storage unit 42 (FIG. 1). Hereinafter, this method will be described in detail.

This method is a method for determining the skin condition of the subject S based on a plurality of condition parameters P (FIG. 3: P1 to P6) representing skin characteristics.
In this method, a plurality of skin factors F (F1 to F13) representing the skin case C are stored in association with each of the plurality of state parameters P1 to P6.
In this method, a factor selection input FS for selecting a part of a plurality of skin factors F as a focused factor FA, a focused factor score SA indicating the expression level of a skin case C related to the focused factor FA, and a focused factor FA other than the focused factor FA An input of the general factor score SC indicating the degree of expression of the skin case C according to the skin factor F (general factor FC) is accepted (FIG. 2: steps S30 and S40).
In this method, the first weight W1 is assigned to the attention factor score SA, the second weight W2 lower than the first weight W1 is assigned to the general factor score SC, and the attention is given the weight W1. The state parameter P is calculated from the general factor score SC to which the factor score SA and the weight ratio W2 are assigned (FIG. 2: step S60).
In this method, the skin condition of the subject S is determined based on the calculated condition parameter P (FIG. 2: step S62).

Next, this method will be described in more detail.
In this method, an input regarding the item used for the beauty related product PD is received from the subject S.
FIG. 5 is a diagram showing a product table TD showing a list of beauty related products PD. The subject S selects and inputs one or more beauty-related products PD that he / she uses on a daily basis from the product table TD displayed on the subject terminal 50 (FIG. 2: step S10). In this method, the number of types of beauty-related products PD that are presented together with the determination result in the product presentation step S90 is increased or decreased according to the items used by the subject S. Specifically, in step S10, No. 7: Base makeup or no. 8: When point makeup is selected and input, the number of types of makeup remover presented in the product presentation step S90 increases.

In the mode selection step S20, the input unit 20 accepts selection of either the fine mode or the simple mode from the subject S as the mode selection MD. When the fine mode is accepted (FIG. 2: step S22 = Y), as will be described below, the calculation unit 10 has the attention factor score SA to which the first weight W1 is assigned and the second weight W2. Based on the state parameter P calculated from the given general factor score SC, the skin condition determination result of the subject S is obtained. On the other hand, when the simple mode is accepted (FIG. 2: Step S22 = N), the input unit 20 omits the input of the factor selection input FS and the attention factor score SA and accepts the input of the general factor score SC. And in simple mode, the calculating part 10 calculates | requires the determination result of the test subject's S skin state based on the state parameter P computed from the general factor score SC. The simple mode will be described later.

<Fine mode>
The fine mode is roughly divided into an input step (steps S30 to S52), a calculation step (steps S60 and S62), and an output step (steps S80 and S90). In step S30, a plurality of skin factors F are presented to the subject terminal 50. The subject S selects a part thereof as the attention factor FA. The attention factor FA is a factor corresponding to the skin case C related to the skin trouble of the subject S. Here, extracting the attention factor FA includes various aspects in addition to selecting a part from the skin factor F displayed in a list. For example, what is necessary is just to distinguish attention factor FA and other skin factors F, such as leaving attention factor FA by selectively erasing other skin factors F which subject S does not pay attention from a list.

The state parameter P in this method includes sebum amount (P1), water retention (P2), dermis or stratum corneum elasticity (P4), melanin content (P6), blood circulation degree (P5), or ceramide amount ( P3), at least one of them.

In addition, the skin factor F in this method includes skin greasy (F1), size or quantity of acne or pimples (F2), range or degree of skin roughness (F3), size of spots or freckles Or density (F4), dullness of skin (F5), breadth or redness intensity of the “bear” around the eyes (F5), depth or quantity of fine lines (F6), degree of stratum corneum (F7) ), The degree of skin tension (F8), the degree or quantity of conspicuous pores (F9), and the redness intensity (F11) or whiteness intensity (F10) of the skin.

As shown in FIG. 3, each state parameter P corresponds to a plurality of skin factors F. A common skin factor F may be associated with a plurality of state parameters P.
The sebum amount P1 is an estimated amount of sebum that covers the surface of the skin so as not to allow moisture to escape. If the sebum is excessive, it will cause greasy skin (F1), acne and pimple (F2), and conspicuous pores (F9).
The water retention power P2 is an estimated value of the force that the whiskers around the keratin fibers constituting the cell catch and retain moisture in the corneocytes. The decrease in the water retention power P2 causes skin roughness, dryness (F3), and stratum corneum tension (F7). In addition, the tension (F8) of the skin such as cheeks is increased.
The amount of ceramide P3 is an estimated amount of ceramide that keeps moisture between keratinocytes and arranges the cells in an orderly manner to adjust the texture of the skin. The decrease in the amount of ceramide P3 causes skin roughness and dryness (F3) similarly to the water retention power P2, and increases the feeling of skin tension (F8). In addition, the decrease in the amount of ceramide P3 causes fine lines (F6).
Elasticity P4 is an estimated value of the elasticity of the skin structure in which elastic fibers in the dermis of the skin bundle collagen. The decrease in elasticity P4 causes fine lines (F6) and conspicuous pores (F8). Moreover, hardening of the stratum corneum also leads to a decrease in elasticity P4. When the skin is pressed locally with a finger, when the stratum corneum is cured, a wide area including a recessed area where the fingertip directly hits is recessed. Therefore, the skin tension (F7) causes a decrease in the elasticity P4. Moreover, the elasticity P4 of the whole skin can be evaluated by the skin elasticity (F12) by pushing back when the skin is pressed with a fingertip.
The blood circulation P5 of the skin represents the quality of skin metabolism. Skin with good blood circulation P5 has a healthy light redness. Skin with poor blood circulation P5 becomes yellowish darkness (F5) or, conversely, has a strong redness (F11) due to congestion. Moreover, the blood circulation P5 of skin can be evaluated by being skin temperature (F13) which feels moderate warmth without a fire when touching a cheek with a palm.
The melanin amount P6 is the skin content of the melanin pigment that determines the whiteness or blackness of the skin color. Skin damage due to ultraviolet rays increases this melanin, causing spots, freckles (F4) and dullness / bearing of the skin (F5). Moreover, when the amount of melanin P6 increases, the conspicuous pores (F9) become conspicuous and the whiteness of the skin (F10) is lost.

In step S30, the transmission unit 58 presents a part or all of the skin factor F included in the skin factor table TF (FIG. 4) to the subject terminal 50. In the present embodiment, skin factors F1 to F11 are presented to the subject terminal 50. The skin factor F10 (skin whiteness) and the skin factor F11 (skin redness) may be collectively presented to the subject terminal 50 as “skin color”.

The subject S selects a part of the skin factors F1 to F11 presented on the subject terminal 50 as the attention factor FA. This method exemplifies a case where skin factor F4 (stains and freckles) and skin factor F5 (dullness and bears) are selected in this order.

In this method, selection of two or more attention factors FA is sequentially accepted as the factor selection input FS, and a different first weight W1 is given to the attention factor score SA according to the selection order of these attention factors FA. Specific numerical values of the first weight ratio W1 will be described later using the weight ratio table TW and the matrices M1 to M12 (FIGS. 12 to 14). In this method, a higher weight is assigned to the attention factor FA having a higher degree of attention of the subject S (for example, the attention factor FA received in the first selection order). Thereby, regarding a plurality of skin factors F of high interest of the subject S such as the first trouble and the second trouble related to the skin condition, the skin condition can be determined in consideration of the order of interest.

FIG. 6 is a diagram illustrating an example of a display screen of the subject terminal 50 when skin factor F4 (stain / sobacus) is selected as the first attention factor FA1. On the subject terminal 50, an attention factor question QA, a skin image display unit 22, and slider units 24a and 24b are displayed. The factor of interest question QA is to select the target site where the skin case C suffering from the subject S has developed, and the slider unit so that the skin image display unit 22 appropriately simulates the degree of expression of the skin case C. This message prompts the subject S to operate 24a and 24b. The target site for each skin case C and the skin factor F are associated with each other in the skin factor table TF of FIG. In this embodiment, representative 1 to 3 expression locations of each skin case C are set as target sites.

In the skin image display unit 22, a first skin image 22a in which a skin case C corresponding to the skin factor F4 is illustrated is displayed. The first skin image 22a is a schematic diagram (illustration) or a photograph including at least a part of the face. As shown in FIG. 4, there are three types of skin factor F4 (spots and freckles) as target sites: nose + cheeks, temples, and under the eyes. A dark portion 22b in FIG. 6 illustrates a stain (liver spot) under the eye.

When the input unit 20 of the skin condition determination apparatus 100 (see FIG. 1) receives the operation input OP of the slider units 24a and 24b of the subject terminal 50, the image transition unit 24 displays the skin case C (see FIG. 6 changes the degree of expression of melasma) in multiple stages. Specifically, based on the operation input OP of the slider 24a in the horizontal axis direction, the image transition unit 24 changes the color (lightness) of the dark color portion 22b illustrated in the first skin image 22a to skin color and brown. Vary between. Further, based on the operation input OP of the slider unit 24b in the vertical axis direction, the image transition unit 24 changes the range of the dark color unit 22b to be wide or narrow.

The subject S arbitrarily refers to a mirror, an image, etc., and operates the slider portions 24a and 24b so that the dark color portion 22b of the first skin image 22a has the same density and spread as the liver spots under his eyes. To do. The input unit 20 of the skin condition determination apparatus 100 acquires the attention factor score SA corresponding to the coordinate positions of the slider units 24a and 24b after the operation. The attention factor score SA is an answer to the question number Q1.

The subject S quantitatively determines the degree of expression of the attention factor score SA in his / her skin by determining the coordinates of the slider parts 24a and 24b using the degree of appearance of the skin case C in the first skin image 22a as a determination index. Can be entered. Therefore, the subject S can easily answer the attention factor score SA in multiple stages.

FIG. 7 is a diagram showing an example of the scoring table TS of the attention factor score SA. The scoring table TS is stored in the skin factor storage unit 42. Regarding the skin factor F in which a plurality of target parts are set, a different scoring table TS for each target part may be stored in the skin factor storage unit 42. When the input unit 20 receives the coordinates of the slider units 24a and 24b, the calculation unit 10 refers to the scoring table TS of the skin factor storage unit 42 and acquires the attention factor score SA indicated by the coordinate values. As shown in FIG. 7, an attention factor score SA is recorded at the intersection of the coordinates (0 to 10) of the slider portion 24a and the coordinates (0 to 10) of the slider portion 24b. In the present embodiment, the lowest of the attention factor scores SA is 2 points, and the highest is 7 points. However, the attention factor score SA is evaluated with a maximum score of 10 irrespective of the highest score stored in the scoring table TS.

The input unit 20 of the present embodiment accepts the input of the factor of interest score SA from 5 to 10 levels (six levels in FIG. 7) based on the operation input OP of the sliders 24a and 24b. That is, attention factor scores SA of 5 to 10 levels are associated with 11 × 11 = 121 permutations of the slider parts 24a and 24b.

For example, when the slider 24a is at the left end (range of melasma: narrow), the coordinate is set to 10. On the other hand, when the slider portion 24a is at the right end (range of melasma: wide), the coordinate = 0. Further, when the slider portion 24b is at the lower end (the color of melasma: light), the coordinate = 10. On the other hand, when the slider portion 24b is at the upper end (the color of the liver spot: dark), the coordinate = 0 is set.
Accordingly, the skin factor C is estimated to be milder as the range of the melasma under the eyes of the subject S input by the slider parts 24a and 24b is narrower and the color is lighter, and the attention factor score SA is set higher. It is. On the other hand, the attention factor score SA decreases as the range of the melasma of the input subject S increases and the color becomes darker. This is because the skin case C of the attention factor FA is estimated to be serious.

In the present embodiment, the subject S sequentially selects a plurality of target portions for one attention factor FA, operates the slider portions 24a and 24b for each, and inputs the coordinate values to the input portion 20. Also good. In this case, the calculation unit 10 may acquire the attention factor score SA with reference to the scoring table TS corresponding to each target region, and acquire the score of the lowest score among them as the attention factor score SA. Thereby, the expression degree of the skin case C can be quantified by the target part where the skin case C is the most serious. In this way, a representative finite number of expression points (target sites) of skin case C are associated with the skin factor F in advance, and one or more of them are selected by the subject S to receive the attention factor score SA. Thus, the expression states of the skin cases of many subjects S can be covered, and the subject S can easily input the attention factor score SA. From this point of view, the number of target parts to be stored in association with the skin factor F in the skin factor table TF is preferably 1 to 5, more preferably 1 to 3.

FIG. 8 is a diagram showing an example of a display screen of the subject terminal 50 when skin factor F5 (dullness / bear) is selected as the second attention factor FA2. On the subject terminal 50, an attention factor question QA, a skin image display unit 22, and slider units 24a and 24b are displayed. The skin image display unit 22 displays a second skin image 22c in which a skin case C corresponding to the skin factor F5 is illustrated. As shown in FIG. 4, the target site of skin factor F5 (dullness / bear) is the entire face and around the eyes. The dark portion 22d in FIG. 8 illustrates the “bear” around the eye.

FIG. 9 is a diagram showing a scoring table TS of the attention factor score SA regarding the second attention factor FA2. In the present embodiment, the attention factor score SA has 6 levels of 3 points as the minimum and 8 points as the maximum. Similar to the scoring table TS of the skin factor F4 shown in FIG. 7, the attention factor score SA is recorded at the intersection of the coordinates of the slider portions 24a and 24b. And when the slider part 24a exists in a left end (bearing range: narrow), it is set as the coordinate = 10. On the other hand, when the slider portion 24a is at the right end (bearing range: wide), the coordinate = 0. When the slider portion 24b is at the lower end (bear color: light), the coordinate is set to 10. On the other hand, when the slider portion 24b is at the upper end (bear color: dark), the coordinate = 0. Then, the attention factor score SA is set to be higher as the “bear” range of the subject S input by the slider parts 24a and 24b is narrower and the color is lighter. On the contrary, the attention factor score SA is set to be lower as the range of “bear” of the input subject S is wider and the color is darker. The attention factor score SA is an answer to the question number Q2.

That is, the dark color portion 22b of the first skin image 22a corresponds to the melasma that is a stain under the eyes, and the dark color portion 22d of the second skin image 22c corresponds to the “bear” around the eyes. Here, melasma is a skin case derived from melanin, and is classified into the same skin factor F4 as a stain. The melasma is derived from the melanin concentration in the deep part of the dermis and is generally expressed symmetrically in both eyes. On the other hand, it is common for a bear to appear on one side of one eye or asymmetrically in the case of both eyes. There are light red “bears” derived from blood circulation caused by congestion around the eyes, and dark brown “bears” derived from melanin at a shallow position of the dermis. The latter skin cases are classified into the same skin factor F5 as the dullness of the skin. In this method, the “bear” around the eyes is classified into the skin factor F5, and when this is derived from melanin (that is, when the color of “bear” is dark), it is determined that the skin case is serious. Therefore, a smaller attention factor score SA is given as the coordinates of the slider portion 24b approach the upper end.

Therefore, in this method, the skin image display unit 22 includes a first skin image 22a having a symmetric dark portion 22b (liver spot) at the lower part of both eyes and a dark portion 22d (bear) that is asymmetrical around the eyes. And a second skin image 22c having. The image transition unit 24 changes the bluish color of the dark color part 22b (liver spot) of the first skin image 22a and the reddish color of the dark color part 22d (bear) of the second skin image 22c.

Thus, in the present embodiment, the symmetry of the dark portions 22b and 22d is different between the first skin image 22a showing melasma and the second skin image 22c showing a bear. Further, it is emphasized that the image transition unit 24 changes the bluishness (the density of the blue component) of the dark color portion 22b in the first skin image 22a, thereby expressing the degree of measles development. On the other hand, the redness (density of red component) of the dark color portion 22d in the second skin image 22c is changed by the image transition portion 24. Specifically, the color of the dark color portion 22d is changed between red and brown. It is emphasized that this represents the degree of expression of “Kuma”.
As described above, the skin factor F4 of melasma and the skin factor F5 of “Kuma” are different from each other. Therefore, if the attention factor score SA is input by confusion between the two, the determination result of the skin state may be greatly different. There is sex. On the other hand, by changing the display mode of the skin image display unit 22 between melasma and “Kuma” as in the present embodiment, the subject S has the dark color around the eyes of his / her face as melasma. The skin factor F can be appropriately selected without confusion about whether it is a “bear”. Thereby, according to this method, the test subject's S skin state can be determined correctly.

In step S40, the transmission unit 58 (see FIG. 1) presents to the subject terminal 50 a general factor question QC related to another skin factor F (general factor FC) that has not been selected as the attention factor FA. Then, the input unit 20 receives an answer to the general factor question QC from the subject S.

FIG. 10 is a diagram showing a general factor table TC showing a list of general factors FC. In this method, a general factor question QC with question numbers Q3 to Q11 is presented to the subject S. Answers to the general factor question QC are selectively received from three options for each question. Two or three general factor scores SC are associated with these three options. In step S40, the input unit 20 of the skin condition determination device 100 acquires the general factor score SC for a part or all of the list of general factors FC.

That is, the input unit 20 selectively accepts the input of the general factor score SC from a plurality of (2 to 3) stage options. Then, the input unit 20 selectively accepts the input of the attention factor score SA from options of multiple levels (5 to 10 levels) than the general factor score SC. Thereby, the subject S can be inquired in detail about the expression level of the attention factor FA, and the subject S can be easily inquired about the expression level of other general factors FC. For this reason, the determination result according to the subject's S trouble can be obtained, reducing the medical examination burden of the subject S.

In step S40, the input of the general factor score SC regarding the skin factor F (skin factors F4 and F5) selected as the attention factor FA is omitted. Thereby, since it is not necessary to input the attention factor score SA and the general factor score SC with respect to the common skin factor F, the burden of interrogation to the subject S is reduced.

In step S50, the transmission unit 58 (see FIG. 1) presents the palpation question QPP to the subject terminal 50. And the input part 20 further receives the palpation score SPP showing the palpation result of the skin which the test subject S performed as a reply with respect to this palpation question QPP.

FIG. 11 is a diagram showing a palpation table TPP showing a list of palpation questions QPP. In this method, up to four palpation questions QPP with question numbers Q12 to Q15 are presented to the subject terminal 50. Q12 is a question regarding skin feel, and is classified into skin factor F3 (skin roughness / dryness). Q13 is a question related to the amount of sebum, and is classified into skin factor F1 (greasiness). Q14 is a question regarding skin elasticity (skin factor F12) derived from the elasticity of the dermis. Q15 is a question regarding skin temperature (skin factor F13).

That is, the palpation score SPP includes a question indicating the degree of elasticity (skin elasticity) of the dermis of the subject S or the skin temperature. Thus, in this method, the question regarding the skin condition that is difficult to appear visually is presented to the subject S as the palpation question QPP. This makes it possible to interrogate not only questions that are determined and input from the appearance of the skin, such as the attention factor score SA, but also skin factors F that are difficult to determine from the appearance.

As with the attention factor question QA, the answer of the palpation score SPP to the palpation question QPP is based on the coordinates of the slider portions 24a and 24b by changing the display mode of the skin image display portion 22 in multiple stages by the slider portions 24a and 24b. The input unit 20 may acquire the information. Moreover, it is preferable that the answer of the palpation score SPP is selectively received from options of multiple levels (5 to 10 levels) than the general factor score SC, similarly to the attention factor score SA. In this method, the palpation score SPP is evaluated with a maximum of 10 points.

In step S30, when the subject S selects the skin factor F3 or the skin factor F1 as the attention factor FA from the skin factor table TF (see FIG. 4) and inputs the attention factor score SA, it overlaps with this in step S50. The palpation question QPP related to the skin factor is omitted. Thereby, the examination load of the subject S is reduced. Specifically, when the subject S selects the skin factor F3 in step S30, the question number Q12 is omitted in step S50. When the subject S selects the skin factor F1 in step S30, the question number Q13 is omitted in step S50. Skin factor F3 (cracking / drying) is a typical question regarding water retention power P2 and ceramide amount P3. For this reason, in either step S30 or step S50, it is preferable to obtain a finer (multistage) answer than the general factor score SC as the attention factor score SA or palpation score SPP. Similarly, skin factor F1 (greasiness) is a typical question regarding sebum amount P1. For this reason, it is preferable that the attention factor score SA or the palpation score SPP is acquired more finely (multistage) than the general factor score SC in either one of step S30 and step S50.

In step S52, the input unit 20 further receives an attribute input indicating the residence area RA, the age AG, or the sex SX of the subject S. As will be described later, in the skin condition determination system 200, statistical data (average score AV) regarding the determination result of the skin condition for each accepted residential area RA, age AG or sex SX is used as the determination result of the skin condition of the subject S ( Output in comparison with skin score SS). The skin score SS is a score obtained by quantifying the skin state of the subject S for each state parameter P.

In step S60, the calculation unit 10 calculates the state parameter P after assigning weights to the attention factor score SA and the general factor score SC. The first weight W1 assigned to the attention factor score SA is larger than the second weight W2 assigned to the general factor score SC. Further, the calculation unit 10 calculates a state parameter P by adding an intermediate weight (third weight W3) between the first weight W1 and the second weight W2 to the palpation score SPP. .

FIG. 12 is a diagram showing the weight ratio table TW. 13 and 14 are diagrams showing matrices M1 to M12 representing the first to third weight ratios W1 to W3. The first to third weight ratios W1 to W3 are defined as elements of the matrices M1 to M12. These matrices are stored in the skin factor storage unit 42 (see FIG. 1).

The calculation of the state parameter P in this method is performed as follows.
As described above, the case where the skin factor F4 is selected as the first attention factor FA1 and the skin factor F5 is selected as the second attention factor FA2 in step S30 is illustrated. As shown in FIG. 3, regarding the amount of sebum P1, the water retention power P2, the amount of ceramide P3, and the elasticity P4, the skin factor F4 or F5 is not included in the corresponding skin factor. Therefore, the skin score SS of these state parameters P is calculated based only on the general factor score SC and the palpation score SPP. As described above, regarding the state parameter P that does not include the attention factor FA, the skin score SS is calculated by assigning a weight equal to the general factor score SC and the palpation score SPP. The amount of sebum P1 will be exemplified and described more specifically. The skin factor F1 (FIG. 10: Q3), F2 (FIG. 10: Q4), F9 (FIG. 10: Q9) general factor score SC associated with the sebum amount P1, and palpation score SPP applied to Q13 are each 0. The score is converted to a score of 1 or less and multiplied by a weight factor of 25. For example, it is assumed that the skin factor F1 (Q3) is 3 points, the skin factor F2 (Q4) is 2 points, and the skin factor F9 (Q9) is 1 point with respect to the general factor score SC (full score of 3). Then, it is assumed that the palpation score SPP according to Q13 is 5 out of 10 points. In this case, the skin score SS = 3/3 * 25 + 2/3 * 25 + 1/3 * 25 + 5/10 * 25 = 62.5 is obtained by converting the score rate for each question from 0 to 1 and multiplying by the weight rate 25. Calculated as a point.
Water holding power P2, ceramide amount P3, and elasticity P4 are calculated in the same manner.

On the other hand, the blood circulation P5, which is the state parameter P associated with the attention factor FA (skin factor F5), is calculated as follows using a matrix. First, since the skin factor F5 is the second attention factor FA2, the matrix (M8) described second in the weight table TW is selected. When the skin factor F5 is the first attention factor FA1, the first matrix (M7) is selected. When the state parameter P includes both the first attention factor FA1 and the second attention factor FA2, the third matrix (M9) is selected.
As shown in FIG. 14, the matrix M8 is a matrix with three rows and two columns. The number of columns of the first and second matrices (M1, M2, M4, M5, M7, M8, M10, M11) in the weight table TW is the palpation score SPP among the skin factors F corresponding to the state parameter P. This corresponds to the number of factors excluding those related to. Since the blood circulation P5 corresponds to two skin factors F (F5 and F11) except for the skin factor F13 related to the palpation score SPP, the number of columns of the matrix M8 is two. Of these, the first column (46, 27, 27) corresponds to the weight when the skin factor F5 is the attention factor FA, and the second column corresponds to the weight when the skin factor F11 is the attention factor FA. These numerical values correspond to the first weight ratio W1 to the third weight ratio W3 in order.
A matrix of three rows and one column obtained by converting the attention factor score SA of the skin factor F5, the general factor score SC of the skin factor F11, and the palpation score SPP of the skin factor F13 into a score rate of 0 or more and 1 or less, respectively, The skin score SS is calculated by performing an inner product calculation with the rate W1 to the third weight rate W3.
Specifically, for example, the attention factor score SA of skin factor F5 is 6 points out of 10 points, the general factor score SC of skin factor F11 is 1 point out of 3, and the palpation score SPP of skin factor F13 is 10 points 5 points out of the maximum. In this case, the skin score SS = 6/10 * 46 + 1/3 * 27 + 5/10 by converting the score rate for each question from 0 to 1 and multiplying by the first weight rate W1 to the third weight rate W3. * 27 = 50.1 points.

Further, the melanin amount P6, which is a state parameter P associated with the first attention factor FA1 (skin factor F4) and the second attention factor FA2 (skin factor F5), is also calculated using a matrix as follows. Is done. In the weight ratio table TW shown in FIG. 12, the third matrix (M12) is selected.
As shown in FIG. 14, the matrix M12 is a matrix with 4 rows and 6 columns. The number of columns of the third matrix (M3, M6, M9, M12) in the weight table TW is two from the number of factors excluding those related to the palpation score SPP among the skin factors F corresponding to the state parameter P. It corresponds to the number of combinations to be selected. Since four skin factors F (F4, F5, F10, and F9) correspond to the melanin amount P6, the number of columns of the matrix M12 is six. Of these, the first column (30, 30, 20, 20) represents the weight when the combination of the first attention factor FA1 and the second attention factor FA2 is the skin factors F4 and F5. That is, the first weight W1 given to the attention factor score SA (skin factors F4, F5) is 30, and the second weight W2 given to the general factor score SC (skin factors F10, F9) is , 20, which is smaller than the first weight factor W1.
Then, an inner product operation of the matrix of three rows and one column obtained by converting the attention factor score SA and the general factor score SC into a score rate of 0 or more and 1 or less and the first weight factor W1 and the second weight factor W2 is performed. Thus, the skin score SS of the melanin amount P6 is calculated.
Specifically, for example, the attention factor score SA of skin factor F4 is 4 out of 10 points, the attention factor score SA of skin factor F5 is 6 points out of 10, and the general factor score SC of skin factor F10 is 3 The general factor score SC of 2 points out of a full score and the skin factor F9 is set as 1 point out of 3 points. In this case, the skin score SS = 4/10 * 30 + 6/10 * 30 + 2/3 is obtained by converting the score for each question from 0 to 1 and multiplying by the first weight W1 and the second weight W2. * 20 + 1/3 × 20 = 50.0 points.

From the above, the skin score SS of the state parameter P is calculated. The skin score SS of the subject S is recorded in the determination result accumulation unit 46, and the average score AV is updated.

Additional notes regarding the matrixes M1 to M3. In the state parameters P1 to P3, when the highest skin factor F1 or F3 shown in FIG. 12 is selected as the first attention factor FA1, 50 is set as the first weight W1, as shown in the matrix M1 in FIG. Is granted. On the other hand, when these skin factors are selected as the second attention factor FA2, 46 is given as the first weight W1, as shown in the matrix M2. In other words, the first weight assigned to the attention factor score SA applied to the second attention factor FA2 is larger than the first weight W1 assigned to the attention factor score SA applied to the first attention factor FA1. W1 is small. Thus, a large weight is given to the attention factor score SA according to the degree of attention of the subject S.

Also, in the state parameters P1 to P3, when the second highest skin factors F2, F7, and F6 shown in FIG. 12 are selected as the first attention factors FA1, the attention factor scores SA for these skin factors F are determined. Thus, 50 is given as the first weight ratio W1. In this case, the general factor score SC is given 15 as the second weight W2, and the palpation score SPP is given 20 as the third weight W3. That is, the factor of interest SA, the palpation score SPP, and the general factor score SC are in order of increasing weighting. Thus, depending on the degree of attention of the subject S and the number of stages of answers to the inquiry, a large weight is assigned in the order of the attention factor score SA, the palpation score SPP, and the general factor score SC.

In step S62, the skin state of the subject S is determined based on the tendency of the skin score SS calculated for each state parameter P. Various methods can be adopted as a specific method for determining the skin condition. In this method, the skin of the subject S is classified into one of the nine skin attributes CS according to the skin score SS of the state parameters P1 to P3, and the subject S is classified into two skin trends according to the magnitude relationship of the state parameters P4 to P6. To do.

FIG. 15 is a diagram illustrating an example of a calculation result of the skin score SS. The description of specific numerical values is omitted. FIG. 16 is a diagram illustrating an example of the skin attribute CS of the subject. In FIG. 16, a product table TD in which identification numbers of beauty-related products PD suitable for each skin attribute CS are associated is also shown.

The skin attribute CS can be classified by the magnitude of the skin score SS of the state parameter P1 (sebum amount) and the magnitude of the average skin score SS of the state parameter P2 (water retention) and the state parameter P3 (ceramide amount). it can. Moreover, you may classify | categorize skin attribute CS further finely for every attribute (residence area RA, age AG, or sex SX) which the test subject S input in step S52.

Specifically, in FIG. 16, the skin score SS of the sebum amount P1 is classified into three groups of o (greasy), n (medium), and d (dry). Furthermore, it classify | categorizes into three groups of A1 (moisture skin), A2 (medium), and B (dry skin) by the magnitude of the average skin score SS of the water retention power P2 and the amount of ceramide P3. In the product table TD of FIG. 16, the age group is further classified into three levels for the nine skin attributes CS obtained by multiplying these groups. In the product table TD, the identification number of the beauty related product PD that matches the subject S of each category is associated. The product table TD is stored in the output information storage unit 44 (see FIG. 1). The calculation unit 10 of the skin condition determination apparatus 100 refers to the output information storage unit 44 and extracts the beauty-related product PD associated with the skin attribute CS to which the subject S belongs.

Further, in step S62, the subject S is determined by the magnitude relationship between the skin score SS of elasticity P4 (hereinafter referred to as elasticity value) and the average skin score SS of blood circulation P5 and melanin amount P6 (hereinafter referred to as skin color value). Are classified into two skin tendencies. When the skin color value of the subject S is larger than the elasticity value, the calculation unit 10 of the skin condition determination device 100 selects the beauty related product PD including the active ingredient for giving priority to the improvement of the elasticity P4 such as the softening of the stratum corneum. Extract. On the other hand, when the elasticity value of the subject S is equal to or greater than the skin color value, the calculation unit 10 of the skin condition determination apparatus 100 includes a beauty-related product including an active ingredient that improves the blood circulation P5 or the melanin amount P6 such as a blood circulation accelerator or a whitening agent. Extract PD.

FIG. 17 is an example of a determination result displayed and output on the subject terminal 50 in step S80. This determination result includes the chart CH, the beauty related product PD, and the beauty advice MSG. In FIG. 17, the specific content of the beauty advice MSG is not shown. The chart CH output by this method is displayed by comparing each value of the skin score SS of the state parameters P1 to P6 related to the subject S and the average score AV of the skin score SS of the population having the same attribute as the subject S. It is a radar chart. The beauty advice MSG is stored in advance in the output information storage unit 44 for each tendency of the skin score SS of the state parameters P1 to P6. The calculation unit 10 refers to the output information storage unit 44 and extracts the beauty advice MSG corresponding to the calculated skin score SS. The calculation unit 10 transmits the beauty advice MSG to the subject terminal 50 through the transmission unit 58, and displays and outputs the beauty advice MSG (see FIG. 1). The output of the beauty related product PD will be described later.

<Simple mode>
When the simple mode is accepted in the mode selection step S20 (FIG. 2: step S22 = N), the mode shifts to the simple mode in which the skin condition is easily determined without inputting the attention factor score SA and the palpation score SPP. The simple mode is roughly divided into an input step (steps S71 and S72), a calculation step (step S73), and an output step (steps S80 and S90). In the simple mode, skin factors F1 to F11 are presented to the subject S as general factor questions QC (see FIG. 10). The subject S operates the subject terminal 50 and inputs the general factor score SC as an answer (FIG. 2: step S71).
Next, similarly to step S52, the input unit 20 receives an attribute input indicating the residence area RA, age AG, or sex SX of the subject S (FIG. 2: step S72).

The calculation unit 10 calculates the state parameters P1 to P6 based on the general factor score SC (FIG. 2: step S73). In the simple mode, no weight is given to the general factor score SC. The skin score SS of the state parameters P1 to P6 is calculated from the total score of the general factor scores SC regarding 2 to 4 skin factors F1 to F11 (excluding skin factors related to palpation) associated with the state parameters P1 to P6 ( (See parameter table TP in FIG. 3). The calculation unit 10 refers to the output information storage unit 44 and extracts the beauty related product PD based on the skin score SS.

<Product presentation method>
In this method, product presentation of the beauty related product PD is performed using the above-described skin condition determination method. This product presentation method classifies the skin state of the subject S into a plurality of categories based on the calculated values of the plurality of state parameters P, and presents the beauty-related product PD previously associated with the classified categories. It is. As shown in FIG. 17, the determination result displayed and output on the subject terminal 50 includes information (image, name, etc.) for specifying the presented beauty-related product PD. In the example shown in FIG. 17, the names of the beauty-related products PD (skin lotion, daytime emulsion, beauty serum, moisturizer) and respective images are displayed and output. The calculation unit 10 extracts the beauty related product PD and the beauty advice MSG stored in the output information storage unit 44 based on the category to which the subject S belongs, and transmits them through the transmission unit 58.

The state parameter P includes the melanin content (melanin amount P6) and the degree of blood circulation (blood circulation P5). The beauty-related product PD may include a moisturizer, a facial cleanser or a makeup remover containing a whitening agent or a blood circulation promoter. Then, when the calculated melanin content (skin score SS of melanin amount P6) is equal to or greater than one threshold, a moisturizer, facial cleanser or makeup remover containing a whitening agent is presented. In addition, when the calculated blood circulation degree (skin score SS of blood circulation P5) is equal to or higher than another threshold value, a moisturizer, face cleanser or makeup remover containing a blood circulation promoter is presented.

Moisturizer is a cosmetic product that contacts the skin for a long time and penetrates the skin. For this reason, the humectant containing the whitening agent in particular can sufficiently obtain the whitening effect as well as the moisturizing effect over a long period of time. Therefore, when the melanin amount P6 of the subject S is equal to or greater than a predetermined threshold, it is very useful to present a moisturizer containing a whitening agent. Further, since the facial cleanser and the makeup remover are applied while rubbing the skin, the effect of massaging the skin is simultaneously exhibited during the application. For this reason, the facial cleanser and makeup remover containing a blood circulation promoter have a high effect of promoting blood circulation of the skin of the subject S and eliminating congestion. Therefore, when the blood circulation P5 of the subject S is greater than or equal to a predetermined threshold, it is very useful to present a facial cleanser or makeup remover containing a blood circulation promoter. Examples of the facial cleanser and makeup remover containing a blood circulation promoter include foam-like agents containing carbon dioxide gas.

In dealing with a skin case, it is necessary to deal with the subject S after grasping the skin condition of the subject S from various angles. For example, acne may worsen if a subject who suffers from acne recommends face washing easily to reduce the amount of sebum. This is because if subject S has skin cases of both acne and dry skin, it is necessary to first improve dry skin by recovering keratinocytes, etc., and then deal with acne. It is because it does not heal. However, just because one of the skin cases of the subject S is dry skin, the acne that the subject S regards as a problem cannot be cured just by presenting the improvement.
On the other hand, according to this method, a high weight is assigned to the attention factor score SA corresponding to the skin trouble of the subject S, and a low non-zero weight is assigned to the other general factor scores SC, and the state parameter P1. ~ P6 is evaluated comprehensively. Thus, it is possible to present the beauty-related product PD that gives priority to the skin factor that the subject S subjectively considers as a problem and also improves the objective skin condition of the subject S.

Further, as shown in FIG. 4, a plurality of target sites are set for some skin cases C. As a result, the subject S can select a part or all of the plurality of target parts and easily and accurately input his / her skin condition as the attention factor score SA. According to the skin state determination apparatus 100 of the present embodiment, the attention factor score SA can be obtained in detail according to the expression state of the skin case C by making the scoring table TS different for each target site. For example, the score of the latter score table TS is set to be low overall in order to judge that a state in which a certain skin case C is expressed prominently locally is more serious than a state in which the skin is expressed on the entire face. Can be kept. In this way, by setting a finite number of target regions for each skin case C, it is possible to obtain the attention factor score SA that accurately represents the skin state while reducing the load of operation input by the subject S. It is.

It should be noted that the present invention is not limited to the above-described embodiment, and includes various modifications and improvements as long as the object of the present invention is achieved.

FIG. 1 illustrates the case where the present method is provided to the subject terminal 50 (computer 52, portable terminal 54) through the network 80, but the present invention is not limited to this. FIG. 18 is a functional block diagram illustrating a modified example of the skin condition determination device 100. The skin condition determination device 100 is a so-called stand-alone device and is installed in a store or the like. The skin condition determination method and the product presentation method performed using the skin condition determination device 100 are the same as those in the above embodiment.

That is, the skin condition determination apparatus 100 according to the modification is an apparatus that determines the skin condition of the subject S based on a plurality of condition parameters P representing skin characteristics, and includes the storage unit 40, the input unit 20, and the calculation unit 10. Including.
The storage unit 40 stores a plurality of skin factors F representing the skin case C in association with each of the state parameters P. The input unit 20 includes a factor selection input FS for selecting a part of the plurality of skin factors F as the focused factor FA, a focused factor score SA indicating the expression level of the skin case C related to the focused factor FA, and the focused factor FA. An input of a general factor score SC indicating the degree of expression of skin case C related to other skin factor F (general factor FC) is accepted.
The calculation unit 10 determines the skin state based on the received factor selection input FS, the attention factor score SA, and the general factor score SC. Specifically, the computing unit 10 assigns the first weight W1 to the attention factor score SA, and assigns the second weight W2 lower than the first weight W1 to the general factor score SC. The state parameter P is calculated from the attention factor score SA assigned W1 and the general factor score SC assigned weight W2. And the calculating part 10 calculates | requires the determination result of the test subject's S skin state based on the calculated state parameter P. FIG.

The skin condition determination apparatus 100 includes an input unit 20 that receives an operation input OP by the subject S and an output unit 56 that performs various display outputs. The output unit 56 presents the attention factor question QA, the general factor question QC, and the palpation question QPP to the subject S, and outputs determination results such as the chart CH, the beauty advice MSG, and the beauty related product PD. Moreover, the image transition part 24 receives the test subject's S operation input OP, and changes the display mode of the 1st skin image 22a and the 2nd skin image 22c. The output unit 56 functions as the skin image display unit 22.
