Detailed Description
Hereinafter, only certain exemplary embodiments are briefly described. As will be recognized by those of skill in the pertinent art, the described embodiments may be modified in various different ways without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.
The freckle-removing evaluation indexes of the freckle-removing effect of the freckle-removing cosmetics are numerous, one of the freckle-removing evaluation indexes is selected and is necessarily one-sided, and if each freckle-removing evaluation index is sequentially used as a dependent variable, the obtained relationship can even contradict each other, and because some freckle-removing effect compositions have an effect on one freckle-removing evaluation index and may not have an effect on the other freckle-removing evaluation index, a reasonable comprehensive index is provided, and the reasonable comprehensive index is very necessary for unifying the evaluation standards of the freckle-removing effect.
Fig. 1 shows a flowchart of a method for evaluating the freckle removing effect of a freckle removing cosmetic according to an embodiment of the present application. As shown in fig. 1, the method for evaluating the freckle-removing effect of the freckle-removing cosmetic may include the steps of:
s110, obtaining N freckle-removing evaluation indexes of the freckle-removing cosmetics, wherein N is an integer greater than 1.
In this embodiment, the freckle-removing cosmetic means a cosmetic having a freckle-removing effect, for example, a cosmetic having a pure freckle-removing effect, a cosmetic having a whitening and freckle-removing compound effect, or the like.
In this embodiment, N speckle removing evaluation indexes may be obtained as follows:
s111, obtaining M freckle-removing evaluation indexes of the freckle-removing cosmetics, wherein M is larger than N.
Illustratively, the M speckle reduction evaluation indexes may include the following 11 speckle reduction indexes: subcutaneous melanin area, epidermal layer melanin area, total area of spots, total number of spots, density of spots, spot area of individual spots, density of individual spots, subcutaneous melanin area ratio, epidermal layer melanin area ratio, spot area ratio of individual spots.
S112, one of at least two freckle evaluation indexes with the same meaning in the M freckle evaluation indexes is reserved, and L freckle evaluation indexes are obtained, wherein N is smaller than L.
For example, in general, the trend of the area ratio change is consistent with the absolute area, and on the basis of the trend, the area ratio data is negligible, and the "subcutaneous melanin area ratio", "epidermal melanin area ratio", "area ratio of the spots" and "spot area ratio of the single spots" in the above 11 spot removal evaluation indexes are screened out.
The situation of single spots and whole spots is repeated to a certain extent in principle, quantization is difficult, the change rate is small, fusion with the index of the whole spots is difficult, and the 'single spot area' and the 'single spot density' in the 11 spot removal evaluation indexes can be screened out on the basis.
S113, screening out irregular freckle evaluation indexes in the L freckle evaluation indexes to obtain N freckle evaluation indexes.
For example, the number of spots may be increased or decreased in the spot-removing process, that is, the total number of spots may be changed irregularly, and the "total number of spots" in the above 11 spot-removing evaluation indexes may be removed on the basis of this.
For example, after the above screening treatment, the above 11 freckle-removing evaluation indexes may be left with 4 freckle-removing evaluation indexes, that is, "subcutaneous melanin area", "epidermal melanin area", "total area of the plaques" and "density of the plaques", for subsequent determination of the freckle-removing evaluation index of the freckle-removing cosmetic.
According to the application, the freckle removing effect of the freckle removing cosmetics can be conveniently quantified by screening and removing M freckle removing evaluation indexes of the freckle removing cosmetics.
And S120, carrying out weight distribution on the N freckle removing evaluation indexes to obtain weight coefficients corresponding to the N target freckle evaluation indexes.
In this embodiment, step S120 may include the steps of:
s121, classifying the N freckle removing evaluation indexes into melanin type freckle removing evaluation indexes and freckle type freckle removing evaluation indexes.
In this embodiment, the N freckle evaluation indexes may be classified into a melanin type freckle evaluation index and a freckle type freckle evaluation index according to whether an influence on skin color is potential or has occurred. It will be appreciated that the melanin-based freckle-removing evaluation index is about to form a spot, the effect of which on the skin color is potential, whereas the freckle-based freckle-removing evaluation index is aimed at an existing spot, i.e. the effect of which on the skin color has occurred.
In this embodiment, the melanin-based freckle-removing evaluation index may include, but is not limited to: subcutaneous melanin area and epidermal melanin area. The spot-type spot-removing evaluation index may include, but is not limited to: the total area of the spots and the density of the spots.
And S122, respectively carrying out weight distribution on the melanin freckle removing evaluation index and the freckle removing evaluation index according to the influence degree on the skin color to obtain a first weight coefficient corresponding to the melanin freckle removing evaluation index and a second weight coefficient corresponding to the freckle removing evaluation index.
Generally, a visual speckle reduction is a need for consumers. The influence of the speckles on the skin color is more than that of melanin, and on the basis, the first weight coefficient can be set smaller than the second weight coefficient in order that the subsequently determined speckle removing evaluation index can meet the speckle removing requirement of consumers. For example, the first weight coefficient may be set to 0.4 and the second weight coefficient may be set to 0.6.
And S123, respectively carrying out weight distribution on any freckle removing evaluation index of the melanin freckle removing evaluation indexes according to the influence degree on the freckle removing effect to obtain a third weight coefficient corresponding to any freckle removing evaluation index of the melanin freckle removing evaluation indexes.
In general, the melanin freckle removing evaluation indexes are in parallel relationship, and it is understood that the melanin freckle removing evaluation indexes do not affect each other, and the freckle removing effect is represented respectively. Because the phenomenon that the total area of the spots is increased but the density of the spots is reduced possibly exists in the spot-removing process, the spot-removing evaluation indexes need to be combined for consideration, and the product between the spot-removing evaluation indexes is taken as a spot-removing evaluation index to jointly represent the spot-removing effect.
In the above case, it is not necessary to give a weight to any one of the freckle-removing evaluation indexes, but it is necessary to give a weight to any one of the freckle-removing evaluation indexes of melanin. In general, the freckle-removing cosmetic is mainly used for blocking melanin generation by inhibiting melanin or decomposing melanin, namely, the freckle-removing cosmetic acts from the inside of skin, and the third weight coefficient corresponding to the subcutaneous melanin area can be set to be larger than the third weight coefficient corresponding to the epidermis melanin area. For example, the third weight coefficient corresponding to the subcutaneous melanin area may be set to 0.6, and the third weight coefficient corresponding to the epidermal melanin area may be set to 0.4.
According to the application, the N freckle evaluation indexes are subjected to weight distribution, so that weights can be respectively assigned to the importance degree of the freckle effect evaluation by the N freckle evaluation indexes, and meanwhile, the correlation among the freckle evaluation indexes can be comprehensively considered, so that the purpose of quantifying the freckle effect of the freckle-removing cosmetics can be achieved.
S130, obtaining the preset MDF of the standard freckle-removing cosmetic.
In this example, the melanin reduction index (Melanine Decrease Factor, MDF) was used to characterize the effect of spot-removing cosmetics in reducing melanin, a measure of reduced melanin area, reduced spot area and reduced spot density.
In this embodiment, a standard speckle removing cosmetic may be understood as a speckle removing cosmetic that serves as a reference.
In this embodiment, the preset MDF of the standard speckle removing cosmetic may be pre-stored in advance, such as stored in a memory, a local or cloud, etc.
S140, determining the freckle removing evaluation index of the freckle removing cosmetics based on the N freckle removing evaluation indexes, the corresponding weight coefficients and the preset MDF index.
In this embodiment, step S140 may include the steps of:
s141, calculating the target freckle-removing comprehensive index value of the freckle-removing cosmetics based on the N freckle-removing evaluation indexes and the corresponding weight coefficients thereof.
In specific implementation, the target speckle reduction comprehensive index value can be calculated according to the following formula (1) based on the N speckle reduction evaluation indexes and the corresponding weight coefficients.
y i ＝α 1 β 1 x 11 +α 1 β 2 x 12 +α 2 x 21 x 22 (1)
Wherein y is i Expressed as a comprehensive index value of target freckle removal, alpha 1 Expressed as a first weight coefficient, alpha 2 Expressed as a second weight coefficient, beta 1 、β 2 A third weight coefficient, x, expressed as the correspondence of the subcutaneous melanin area and the epidermal melanin area, respectively 11 Expressed as subcutaneous melanin area, x 12 Expressed as the area of the epidermis layer melanin, x 21 Expressed as the total area of the spot, x 22 Expressed as the density of the spots.
As one example, the subcutaneous melanin area, the epidermal melanin area, the total area of the plaques, and the density of the plaques can be characterized as averages of the relative rates of change.
For example, when the conventional speckle removing cosmetic is speckle removing cosmetic a, 8 users can change the values of the subcutaneous melanin area, the epidermal melanin area, the total area of the speckle and the density of the speckle on days 1 (i.e., 0 d) and 56 after using the speckle removing cosmetic a for 56 days, respectively, as shown in tables 1 to 3.
TABLE 1
TABLE 2
TABLE 3 Table 3
For example, the numerical references corresponding to the products of the standard freckle-removing cosmetics and the freckle-removing cosmetics a in the subcutaneous melanin area, the epidermis layer melanin area, the total area of the plaques and the density of the plaques can be shown in table 4.
TABLE 4 Table 4
Based on Table 4 above, at α 1 、α 2 、β 1 、β 2 Under the condition of 0.4, 0.6 and 0.4, the corresponding values are respectively substituted into the formula (1) to calculate the target speckle reduction comprehensive index value y i ＝-6.00。
