Evaluation of Effect

1. Instrument and sample

The instrument comprises the following steps: Visia-CR (Canfield); Image-Pro skin Integrated analysis software (MediaCybernetics).

Sample preparation: the foundation solutions of examples 1 to 5 and the foundation solutions of comparative examples 1 to 5 were in total 10 types.

2. Selection of the subject

Qualified volunteers were selected and signed with informed consent to ensure that 80 final volunteers were completed and 8 volunteers were tried for each sample.

And (3) inclusion standard: healthy female volunteers with a habit of using make-up products daily, Chinese people, 18-45 years old; is not sensitive to common cosmetics; the compliance of the subjects is high.

Exclusion criteria: those who have used antihistamines for the last week or immunosuppressants for the last month; those who have used any anti-inflammatory drug on the test site in approximately two months; insulin-dependent diabetic patients; patients suffering from respiratory diseases undergoing treatment; people with allergic constitution, allergic dermatitis and the like have a skin disease history; people who are receiving dermatology treatment or people who take light basic acids, whitening and anti-aging medicines within one month; the tested area has large area of birthmarks, scratch marks, leukoplakia, pigmented nevi, keloids and other skin characterizers which influence the test.

3. Test flow

This test is based on comparative tests before and after makeup of the make-up base product. And respectively carrying out a makeup effect test after 10 types of base makeup products are used independently, collecting Visia-CR facial images and analyzing related indexes. The test environment is kept constant temperature and humidity, the temperature is 21.0 +/-1.0 ℃, and the humidity is 50% +/-10%.

Before testing, a subject firstly cleans the face uniformly according to requirements, takes a rest for 20min between constant temperature and constant humidity, and uses Visia-CR to collect facial images before being used as a smearing sample (t)₀) The initial face image of (a); then, after using the basic skin care products (water, essence, emulsion and cream) which are uniformly provided, smearing the base makeup product to be tested according to the instruction of sample use and according to the 2mg/cm²The amount of (a) is applied until the skin is sufficiently attached (t)₁) Acquiring a second facial image using Visia-CR; 8h (t) after smearing₂) And acquiring a face image by using Visia-CR again to obtain a third face image.

4. Image selection and parameter setting

5 light source modes are built in the Visia-CR, namely standard light 1, standard light 2, cross polarized light, parallel polarized light and UV light, and 5 images can be obtained simultaneously by taking pictures each time. The research selects a standard light 1 image, namely a white light image, which can be used for qualitative observation and clinical evaluation of skin characteristics and makeup improvement before and after makeup of a makeup base product; the standard light 2 image is suitable for quantitative analysis of most surface skin parameters in the test method, including related parameters representing spots, skin color uniformity and skin smoothness, because the influence of bright spots and shadows is reduced; the parallel polarized light image generates a parallel polarized light source through a parallel polarizing film, and can better reflect the surface morphology of the skin, such as pores, fine lines and the like, through surface reflection; and fourthly, calculating the parallel polarized light image and the cross polarized light image to obtain a new image, and further analyzing to obtain the skin glossiness data.

According to the purpose of the test, the image type is selected and the relevant parameters and the corresponding cosmetic effects reflected by the parameters are extracted, as shown in table 2 below.

TABLE 2 image types, associated parameters and cosmetic effects characterized thereby

By utilizing the ghost image positioning function of Visia-CR, good superposition of facial images at different measurement time points can be realized, and the consistency of a subsequent interested analysis region (AOI region) is ensured. According to the requirements, circular, elliptical, square and irregular AOI areas can be set, selected and stored, and can be imported into facial images shot at different measurement time points to obtain effective data and perform front-back comparison analysis.

5. Analysis of results

This experiment was conducted by comparing t for each product₁And t₂The average value of the increase rate of the spot parameter and the pore parameter is used for judging the durability of the composition; the higher the increase rate, the lower the makeup effect and the worse the durability.

Blob count increase ratio (t) is the blob count₂) Spot count (t)₀) -spot count (t)₁) Spot count (t)₀)

Pore count increase ratio (t pore count)₂) Pore count (t)₀) -pore count (t)₁) Pore count (t)₀)

5.1. Blob parameter analysis

And introducing a standard light 2 image for spot analysis, and selecting the spots, the acne spots or other flaw parts of the subject from the AOI area. And (3) calculating a Spot module of the macro part by using Image-Pro software, and directly acquiring related parameters of the skin spots in the AOI region. Representative spot counts and spot area ratios (spot area/AOI area) were selected for analysis.

5.2 pore parameter analysis

Parallel polarized light images need to be led in for Pore analysis, the two sides of the nasal wing or the cheek area with thicker pores are selected in the AOI area, Image-Pro software calculates the Pore module of the macro part, and Pore data in the AOI area can be directly calculated. The pore count and the pore area ratio (pore area/AOI area) are selected as analysis parameters to reflect the pore condition and the pore hiding effect of the product.

6. Results of the experiment

From the above results, it can be seen that: the increase ratio of the spot count and the increase ratio of the pore count of the subjects using the foundation solutions of examples 1 to 5 were significantly lower than those of the subjects using the foundation solutions of comparative examples 1 to 5. Therefore, when the film forming agent is composed of acrylic acid (ester)/polydimethylsiloxane copolymer, hydrogenated polycyclopentadiene and acrylic acid (ester)/ethylhexyl acrylate copolymer in the dosage ratio of 1-3: 1-2: 1.5-3, the foundation solution has a good long-acting makeup holding effect. In examples 1 to 5, the long-acting makeup-holding effect of example 1 is the best, which indicates that the long-acting makeup-holding effect of the foundation fluid is the best when the film-forming agent is composed of the acrylic acid (ester)/polydimethylsiloxane copolymer, the hydrogenated polycyclopentadiene and the acrylic acid (ester)/ethylhexyl acrylate copolymer in the dosage ratio of 2:1.5: 2.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
