JP 2008-029573 A Japanese Patent Laid-Open No. 10-43141

  Generally, face line sagging is considered to be a decrease in skin elasticity or an increase in subcutaneous fat, but even if the amount of sagging is simply evaluated based on images before and after the cosmetic treatment. However, it is not clear what the sagging factor depends on whether the amount of sagging is improved or not.

  Therefore, even if the amount of sag is evaluated before and after the beauty method, it is difficult to appropriately counsel a beauty method to be performed thereafter.

  On the other hand, an object of the present invention is to present a sagging improvement effect for each sagging factor and provide beauty advice based on the sagging improving effect.

  In order to achieve the above object, the present invention provides a method for presenting a sag improving effect by measuring a subcutaneous tissue thickness and / or a subcutaneous blood volume before and after a cosmetic method, and presenting the measurement result to a patient. To do.

  The present invention also provides a beauty advice method for advising a beauty method for improving sagging based on the above measurement results.

  According to the present invention, before and after the treatment of the cosmetic method, three factors of sagging, ie, subcutaneous tissue thickness and / or subcutaneous blood volume, preferably subcutaneous tissue thickness, subcutaneous blood volume and skin elasticity, are measured, and the measurement results are obtained. Since it is presented to the patient, the sagging improvement effect can be shown for each sagging factor. Therefore, the beauty treatment recipient knows the factors that contribute to the improvement of the sag based on the presence or absence of the sag improvement effect that can be recognized by the appearance and the presence or absence of the sag improvement effect according to the presented sag factor. Can do. In addition, the beauty advisor can appropriately select a beauty method effective for improving the sag, or can make corrections at any time and counsel the patient.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

  The method for presenting the sag improving effect of the present invention is as follows: (i) Increase / decrease in sag is less correlated with changes in blood volume at a depth close to the skin surface and correlated with subcutaneous blood volume at a predetermined depth from the skin surface. (Ii) As a factor of sagging, there is an increase in subcutaneous tissue thickness and a decrease in subcutaneous blood volume in addition to the conventionally known decrease in skin elasticity. (Iii) In the age group of 40 years or older, the thickness of the subcutaneous tissue and the volume of subcutaneous blood are the major factors in the age group of 40 years or older. (Iv) The factors that affect the thickness of subcutaneous tissue, subcutaneous blood volume, and skin elasticity are the main factors of sagging, which varies from individual to individual, and depends on the balance of these three factors. For example, skin elasticity When the skin is high, the subcutaneous assembly is less than when the skin elasticity is low. Thickness sagging across the skin even thicker is based on the inventor's finding that less likely to occur. Therefore, the method for presenting the sagging improvement effect of the present invention is a measurement result of subcutaneous tissue thickness and / or subcutaneous blood volume before and after the cosmetic treatment, preferably, measurement result of subcutaneous tissue thickness, subcutaneous blood volume and skin elasticity. To the patient.

  Here, the subcutaneous tissue thickness refers to the thickness of the tissue from below the skin to above the muscle. As the measured value of the skin tissue thickness, a numerical value measured by an ultrasonic diagnostic apparatus, an optical subcutaneous fat measuring apparatus, or the like can be used.

  The subcutaneous blood volume refers to the blood volume (total amount of hemoglobin in blood) existing at a depth range of 10 mm or more from the skin surface, for example, on the cheeks or masseter muscle, at a depth of 15 to 30 mm from the skin surface. The blood volume is preferred. If the depth range in which the subcutaneous blood volume is measured is common before and after the cosmetic method, the relationship between the change in the subcutaneous blood volume and the increase or decrease in sagging can be understood, so the numerical range itself is not strictly limited. However, as described above, a change in blood volume in a range where the depth is shallower than 10 mm is not preferable because it has a low correlation with the increase or decrease in sagging.

  The subcutaneous blood volume refers to the total amount of blood hemoglobin as described above, and is also distinguished from the blood flow volume that means the blood flow rate per unit time.

  As a measurement value of the subcutaneous blood volume, light in the near-infrared region from visible light is irradiated into the tissue from the irradiation point on the skin surface, and light attenuated by absorption and scattering at a plurality of light receiving points different from the irradiation point. It can be obtained by spectroscopic method that obtains the total amount of oxygenated hemoglobin and deoxygenated hemoglobin by receiving and calculating the light absorption coefficient of oxygenated hemoglobin and deoxygenated hemoglobin depending on the wavelength of light. it can. In this case, the measurement depth is determined by the distance between the irradiation point and the light receiving point.

  As the skin elasticity measurement result, it is only necessary to obtain a measurement value that is a parameter of skin elasticity. For example, the amount of change in the skin measured when the probe is pressed against the skin and suctioned and released. Alternatively, a measured value of the amount of displacement of the skin caused by injecting compressed gas into the skin, a parameter obtained by analyzing changes in the surface image when an external force is applied to the skin, and the like can be used. Among these, as a commercially available apparatus for measuring skin elasticity by performing suction and release of skin, for example, CUTOMETER SEM (manufactured by C & K) can be used.

  FIG. 3 shows (a) the relationship between the sagging score near the mouth corner and face line and the subcutaneous tissue thickness, and (b) the sagging score near the mouth corner and face line and subcutaneous, obtained for 40 middle-aged and older people aged 40 to 69 years. Fig. 4 is a relationship diagram of blood volume, (c) a relationship diagram of sagging scores near the mouth corner and face line, and skin elasticity. Fig. 4 shows the same relationship diagram obtained for 29 young people aged 20 to 39 years. It is.

  Here, the sagging score is 7 of 1, 1.5, 2, 2.5, 3, 3.5, 4 by the three expert evaluators using the photo scale of scores 1 to 4 shown in FIG. The score of the stage is determined, and the average value is defined as a sag score near the mouth corner and the face line. This sag score indicates that the greater the score value, the greater the sag.

  In FIGS. 3 and 4, the subcutaneous tissue thickness is measured with a reflected light intensity image from the skin surface to the subcutaneous surface on the face line FL shown in FIG. 6 using an ultrasonic diagnostic apparatus (Aprio, manufactured by Toshiba) (12 MHz). It is a numerical value obtained by measuring the thickness L1 from below the skin to above the muscle.

  Subcutaneous blood volume was measured with a tissue oxygen monitor (BOM-L1 TR W, manufactured by OMEGA WAVE) using near-infrared spectroscopy for each part on the cheek and masseter muscle shown in FIG. 6, and laser wavelengths 780 nm, 810 nm, and 830 nm. These are numerical values obtained by calculating the tissue whole blood cell volume at a measurement depth of 15 to 30 mm.

  For skin elasticity, a CUTOMETER SEM (C & K) probe is used. As shown in FIG. 8, the probe 2 is pressed against the skin 1 on the face line FL, and the inside of the probe 2 is decompressed as shown in FIG. The chamber 3 optically measures the skin displacement UF after 5 seconds of suction and the decrease UR after 1 second of suction when the suction is released after 300 seconds of suction at 300 mb. UR / UF is calculated as a parameter of. In FIG. 8, 1a represents the epidermis, 1b represents the dermis, and 1c represents the subcutaneous tissue.

  From FIG. 3, it can be seen that in the middle-aged group, each of the subcutaneous tissue thickness, the subcutaneous blood volume, and the skin elasticity is correlated with the sagging score near the mouth corner and the face line, and thus these are sagging factors.

  On the other hand, from FIG. 4, in the younger group, there is a correlation between skin elasticity and sagging score near the mouth corner and face line, but the sagging score near the subcutaneous tissue thickness and blood volume and mouth angle and face line It can be seen that there is no correlation, and that younger people have higher skin elasticity than middle-aged and older people and lower sagging scores near the mouth corner and face line.

  In this way, the skin elasticity is the main factor of sagging in young people because the young people have high skin elasticity, so even if the subcutaneous tissue thickness increases or the subcutaneous blood volume decreases, This is thought to be due to the appearance of sagging facial appearance. Therefore, the present invention that presents a sag improvement effect for each sag factor is preferably applied to middle-aged and elderly people. In addition, the balance of the three sagging factors of subcutaneous tissue thickness, subcutaneous blood volume, and skin elasticity is sagging so that the magnitude of skin elasticity in young people is related to the influence of sacrificial tissue thickness and subcutaneous blood volume sagging. The effect is the same for middle-aged and elderly people, and which of the three sag factors is the main sag factor varies from individual to individual. Therefore, in the present invention, before and after the treatment of the cosmetic method, the sacrificial tissue thickness and / or the subcutaneous blood volume, preferably the sacrificial tissue thickness, the subcutaneous blood volume, and the skin elasticity are three slacks. It is preferable to measure the factors so that changes in the respective measured values can be understood.

  In the present invention, it is generally preferable that the site for measuring the factor of sagging is the face region below the cheek, in view of sagging sagging.

  As a presentation form of the measurement results, it is widely included to present changes so that the change in the measurement results before and after the beauty method treatment can be understood, and individual measurement values may be presented as they are, or before and after the beauty method treatment. The difference between the measured values may be presented, or may be presented as a graph as appropriate.

  For example, as shown in FIG. 1, it can be represented on a radar chart. As a result, it is possible to easily recognize the sagging factor that has been improved before and after the cosmetic treatment and the sagging factor that has not been improved. Therefore, the patient knows the main sag factor by combining the presence or absence of a sag improvement effect that can be recognized by the appearance, and the beauty advisor selects an effective cosmetic method for sag, or corrects it as needed. Can be recommended.

  In addition, as shown in FIG. 2, when a specific cosmetic method is continuously performed for a certain period (for example, 16 weeks), the measured values of each sag factor are shown in a graph over time so that the change can be understood. May be. Thereby, it can be easily predicted whether or not each sag factor is improved by continuing the beauty method in the future. In this case, the measurement values of a plurality of measurement sites (for example, on the cheek and masseter) may be shown simultaneously.

  The beauty advice method using the presenting method for improving sag according to the present invention basically reduces or eliminates sag based on the presentation of measured values of sagging factors such as subcutaneous tissue thickness before and after the cosmetic method. Therefore, it is a method of recommending a beauty method such as an effective massage. However, from the correlation shown in FIG. 3, it is possible to roughly estimate the main sag factor in the person to be treated by measuring the sag factor such as subcutaneous tissue thickness only before the cosmetic method. In this case, the relative score value of the subject with respect to the average score obtained from the correlation of FIG. 3 is displayed on a triangular radar chart similar to that of FIG. 1, and based on this, the main slack factor of the subject is roughly determined. You may guess. Thus, it is possible to select a cosmetic method that is generally effective for reducing or eliminating sagging even at the start of the cosmetic method. Then, after the treatment of the cosmetic method, again measure the slack factor such as the subcutaneous tissue thickness, and by comparing the measured values before and after the cosmetic method using the radar chart shown in FIG. We can advise you on the exact beauty method.

  For example, if there is a concern that a small amount of subcutaneous blood contributes to sagging from the radar chart displayed in the same manner as in FIG. 1, and a cosmetic method for increasing the subcutaneous blood volume is recommended, a blood circulation promoter, etc. Dermatology is effective when a cosmetic method that enhances skin elasticity is recommended by advising the use of cosmetics containing skin, or if necessary, the implementation of deep massage using hands or massage equipment, thermal stimulation, or a combination thereof Advise the use of cosmetics containing ingredients. Thereafter, the subcutaneous tissue thickness, subcutaneous blood volume, and skin elasticity are also measured after the cosmetic method. As a result, for example, as shown in FIG. 1, the subcutaneous blood volume increased and the skin elasticity increased before and after the treatment, but the skin tissue thickness remained unchanged and the appearance was not sufficiently improved in sagging Is recommended to use a cosmetic method to reduce the thickness of the subcutaneous tissue by applying mechanical stimulation to the subcutaneous tissue. More specifically, the use of cosmetics containing ingredients effective in reducing fat and the frequency of performing massage that acts deeply. Give advice such as increasing

  In addition, as shown in FIG. 2, when the measurement values of a plurality of measurement sites are obtained, the change in the measurement value of each sag factor is known for each measurement site. Advise effective beauty methods. For example, if the subcutaneous blood volume on the masseter muscle is low and does not improve, but the subcutaneous blood volume on the cheeks is improved, a partial deep massage is advised so that the subcutaneous blood volume on the masseter muscle is improved.

  It should be noted that each measuring device for measuring subcutaneous tissue thickness, skin elasticity and subcutaneous blood volume is connected to a computer so that the radar chart of FIG. 1 can be automatically displayed on the display. A sag evaluation device or a beauty advice device may be constructed so that an expected sag factor and a cosmetic method effective for the sag factor are output. In this case, for each display pattern of the radar chart, the computer is equipped with a database in which an assumed sag factor and a cosmetic method effective for the sag factor are accumulated.

  The present invention is useful for effectively performing a beauty method such as massage for improving sagging.
