Whitening cosmetics have been developed from physical masking and whitening, physical and chemical peeling, and interference with and blockage of normal melanin metabolism.

The color of the skin is determined by the amount, type, and pattern of melanin synthesis by melanocytes and its distribution around keratinocytes. Melanocytes, a small cell of humans, are also a key factor in melanin production, and are involved in melanin production and distribution, as part of the paracrine between keratinocytes and melanocytes, where melanin production is regulated by signaling elicitors released by keratinocytes. Endothelin-1, a keratinocyte-derived regulator of melanin production, binds to specific melanocyte receptors (ETBR) and thereby improves skin pigmentation.

The external environment (ultraviolet rays, living radiation, irregular work and rest, products with poor use quality and the like) can cause skin spots to be bushy and dull. In addition to the effects of factors on external dietary work, physical protection, health, mental status, the intrinsic pigmentation of the skin depends on the action of melanocytes and on stimulation by keratinocyte-derived primers.

It is important to consider whether the prevention of UV irradiation, the interference with the transmission of melanocyte activation information, the inhibition of melanin synthesis, the prevention of melanin transfer, or the acceleration of melanin metabolism. Because many harmful substances of intermediates are generated in the process of generating interfered or blocked skin melanin, due to individual difference, after some people use the currently marketed whitening products, the skin can be damaged to different degrees, even the original defense function of the skin is destroyed, the skin is more sensitive and vulnerable, rather, the skin aging is accelerated, and factors which are not good for the skin health are generated if the whitening products are continuously used for a long time.

A. Reduced melanin level test

20 female volunteers aged 35-55 years were subjected to the test, and after applying the skin care composition provided in example 1 of the present application (defined as SBRIGHTESSENCE composition, the same applies below) at a concentration of 3% to the heavy spot, and repeating the treatment for 2-3 times for 1 day for 2 weeks, melanin was extracted from the cells and quantified by absorbance, it was shown that the melanin content in the melanocytes was reduced by about 18.2% by the treatment with the skin care composition, as shown in FIG. 3 and FIG. 4.

B. Inflammation, facial pigmentation and skin barrier test

30 volunteers (5 male, 25 female, 15 25-35 years old and 15 35-50 years old) were half-face tested for 8 weeks by using a whole set of skin-care products (including skin-care water, essence, cream and cream) containing 3-5% of a skin-care composition on the basis of not changing the existing lifestyle, and were applied 2 times a day. After the experiment was completed, the pigmentation of the cheek and the like of the volunteers were subjected to image analysis.

(a) The half-face inflammation was significantly improved in the same person without changing lifestyle, using a blank product containing no skin care composition, and using a finished product containing the skin care composition for 8 weeks in the half-face as shown in fig. 5 (observed under the lens of laboratory VISIA 7).

(b) Skin brightness (L) and an individual type angle (ITA °) were measured using a spectrophotometer, and the difference between hyperpigmented and nonpigmented skin was compared.

The results showed that the L x value (brightness value) and the ITA ° value (mottle value) of normal skin and skin with excessive pigmentation were both increased (higher values, lighter skin color), and the difference in ITA ° value between mottle and normal skin was reduced by 12.7%, indicating that the skin care product containing the skin care composition had the effect of lightening and evening skin color (as shown in fig. 6, 7a and 7 b), and that the deposition of hemifacial pigment was significantly improved for 8 weeks using the skin care product containing the skin care composition (experimental camera: VISIA7), as shown in fig. 8.

(c) Compared with the same person, without changing living habits, the essential milk containing the skin care composition with the content of 3% is applied to the spot with heavy spots for continuous use for 8 weeks, as shown in fig. 9 and 10, the size of the pigmentation spot is reduced, and the content of melanin in the spot is reduced (observed under the lens of VISIA7 in laboratory).

(d) Using a skin care product containing the skin care composition for 8 weeks, resulted in thicker and firmer stratum corneum, approximately 7-8 well-formed corneocytes (as shown in fig. 11), compared to the blank product (without the skin care composition of example 1), demonstrating that 8 weeks of finished product containing the skin care composition enhances the skin's protective barrier.

As can be seen from the in vivo test results, the skin care product using the skin care composition provided in example 1 of the present application significantly reduced pigmentation, strengthened the skin barrier on the face, and improved the inflammatory state of the face.

In summary, the skin care composition provided by the application has wide raw material sources and good permeability, and has good effects of lightening pigments and improving skin quality on dark and dull skin, rough texture and pigmentation. The preparation method is simple and easy to operate, and is beneficial to effectively absorbing the effective components in the skin care composition by the stratum corneum and improving the utilization rate of the effective components.
