Description

Technical Field

[0001] The present invention relates to a variety of novel cosmetic compositions for improving (especially skin) keratin and in particular for reducing, fading and removing skin pigment spots and pigment marks. The present invention also relates to a skin care method for whitening skin, reducing and / or removing and / or fading pigment spots. Background Art

[0002] Melanin is a pigment that is responsible for the coloration of human skin and hair. Melanogenesis is the process by which melanin is produced by specialized dendritic cells called melanocytes, located beneath or between the basal cells of the epidermis. Melanin produced by melanocytes is then transferred to keratinocytes, the outermost layer of the skin.

[0003] While melanin plays a key role in protecting the skin from harmful UV rays, abnormally high levels of melanin production and accumulation in the skin can lead to hyperpigmentation. The more melanin the melanocytes produce, the darker the skin's pigmentation. This can result in undesirable brown pigmented spots such as age spots, freckles, liver spots, melasma, vitiligo, or post-inflammatory hyperpigmentation caused by abrasions, burns, wounds, or dermatitis.

[0004] Many factors can lead to increased melanin production, which causes skin pigmentation. These factors can be related to the natural aging process and genetic influences, or they can be related to environmental factors such as exposure to ultraviolet (UV) light from the sun, inflammation, acne, stress, hormonal changes or pollution.

[0005] Although generally harmless, pigmentation on the skin, especially on the face, is often considered unsightly.

[0006] It is understood that various skin whitening agents that inhibit melanin production can prevent skin pigmentation or lighten pigment spots.

[0007] These whitening agents are mainly hydroquinone and its derivatives (such as arbutin and deoxyarbutin), ascorbic acid, kojic acid, azelaic acid, polyphenols (such as resveratrol) and isoflavones (such as glabridin). However, some of these whitening agents (such as hydroquinone), although effective, are known to cause melanocyte cytotoxicity and increase skin pigmentation. In addition, kojic acid and its derivatives have the disadvantage of being somewhat toxic and cannot be used in high doses in consumer products. In addition, in some cases, the use of these whitening agents may not be effective for people with severe pigmentation, freckles or age spots. In addition, these active ingredients will only have an effect after several weeks of continuous use, and, for toxicological reasons, the use of products containing certain active ingredients for too long may sometimes be unacceptable.

[0008] There are also some whitening agents, such as soybean extract and niacinamide and its derivatives, which are believed to improve skin appearance and reduce pigmentation by regulating the process of melanocyte transfer of melanin to keratinocytes. However, the effectiveness of these whitening agents still needs to be improved.

[0009] Patent No. EP2522331 provides a cosmetic composition consisting of niacinamide and resveratrol.

[0010] Patent No. EP3791932 provides a cosmetic composition comprising sclareolide, kojic acid and ascorbyl glucoside.

[0011] Patent No. FR3056106 provides a composition containing extracts of Dictyopsis ferns. Patents FR2926220 and FR3070864 provide cosmetic compositions containing extracts of Narcissus sutchuenensis.

[0012] The prior art also provides a composition consisting of a sea daffodil extract and a fern-like tricholoma extract, or a combination of a sea daffodil extract, a fern-like tricholoma extract and niacinamide.

[0013] Although the prior art provides skin lightening agents and compositions, there remains a need for new compositions that are safer, better tolerated by the skin, and more effective for whitening and reducing pigmentation.

[0014] Furthermore, there is a need for new compositions that are non-toxic, relatively inexpensive, and preferably of natural origin.

[0015] Applicants have discovered that the combination of Dictyoptera extract, Iris florentina extract and niacinamide has a surprising effect on whitening and / or improving keratinization, especially of the skin, and reducing and / or eliminating pigmentation imperfections associated with the blotchy appearance of the skin.

[0016] The applicant has also developed a novel cosmetic composition, which comprises at least one whitening agent combination, which comprises a fern-like clematis extract, niacinamide, a sea daffodil extract and a Florentine iris extract. It is observed that these preparations act synergistically and have significant whitening, lightening and even skin tone effects, especially this combination is used for a short time and has significant effects.

[0017] The composition of the present invention is mainly composed of plant extracts, and thus has the advantages of being easy to industrialize, easy to formulate, and very stable. In addition, the various compounds used are also easily available and extracted from renewable resources, so the cosmetic composition can be produced according to the principle of sustainable development.

[0134] 2. Evaluation of the Skin Whitening Effect of the Composition

[0135] 2-1-Scheme:

[0136] 18 women and 2 men (aged between 24 and 65 years old, skin phenotypes IV, V and VI) and 21 women (aged between 33 and 67 years old, skin phenotypes I, II and III) were selected to test the composition of the present invention.

[0137] During the test, the composition was applied to the face twice a day to measure the color of skin phenotypes I, II, III and IV, V, VI; the composition was applied to the forearm twice a day to measure its moisturizing effect. The subjects had normal to dry skin with pigmentation spots, fine lines and wrinkles. The subjects used the composition twice a day for 8 weeks. The measurements were taken at the first examination and the results were recorded as D0 results; the measurements were taken at the intermediate examination after 4 weeks and the results were recorded as D28 results for phenotypes I, II and III; the measurements were taken at the final examination after 8 weeks and the results were recorded as D56 results for phenotypes IV, V and VI.

[0138] 2-2- Evaluation of skin tolerance of the composition of the present invention:

[0139] Clinical examinations performed by dermatologists have shown that the compositions according to the invention have very good skin tolerance.

[0140] 2-3) Subjective evaluation of the efficacy of the composition of the present invention by the subjects through a self-assessment questionnaire:

[0141]

[0142] 2-4-Clinical scoring

[0143] The following parameters were scored clinically visually by dermatologists on a scale of 1–9:

[0144] - Skin tone evenness: 1 means uneven skin tone with spots and blemishes; 9 means even skin tone with no spots and blemishes.

[0145] - Skin gloss: 1 means the skin is dull and lackluster; 9 means the skin is radiant and glowing.

[0146] - Skin color transparency: 1 means dark skin with severe pigmentation; 9 means fair skin with light pigmentation. The values ​​measured at D56 were compared with the initial values ​​at D0 using the non-parametric Wilcoxon test (significance: P < 0.05). The results will be quantified and expressed as the mean of statistically significant differences.

[0147] - Spot color intensity: 1 means the spot is very dark and highly pigmented; 9 means the spot is very light and has low pigmentation.

[0148]

[0149] According to the above results, the use of the composition of the present invention for more than 4 weeks can significantly improve the uniformity and transparency of skin color and skin radiance; the effect is even better after 8 weeks of use. The composition of the present invention can also reduce the intensity and size of pigment spots.

[0150] 2-5- Chromaticity evaluation

[0151] The following parameters were evaluated using a CR-400® Colorimeter:

[0152] • Gloss, denoted as “L*”,

[0153] • Yellow-blue hue, denoted as “b*”,

[0154] •Intensity of skin pigmentation, recorded as “ITA°” (Individual Typological Angle).

[0155] The calculation formula of the parameters is as follows:

[0156]

[0157] The values ​​measured at D56 were compared with the initial values ​​at D0 using Student's t-test (significance: P < 0.05). The results will be quantified and expressed as the mean of statistically significant differences.

[0158]

[0159] (1) The average of three consecutive measurements at the same site.

[0160] Based on these results, we can see that after 4 weeks of using the composition, there are statistically significant differences in skin radiance (L*) and pigmentation (ITA°), and after 8 weeks of use, the differences are even greater. An increase in the L* parameter indicates brighter skin, while an increase in the ITA° parameter indicates a whiter complexion.
