Description

Active composition for repairing ultraviolet injury, preparation method and application thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to an active composition for repairing ultraviolet injury, and a preparation method and application thereof.

Background

Ultraviolet rays are the most important external factor causing skin aging, the ultraviolet rays can directly damage DNA, and the DNA has a plurality of absorption peaks near 260nm, so the DNA can absorb the ultraviolet rays to perform chemical reaction. UVA emitted from the sun is 10 times higher than UVB, which can penetrate the epidermis to the dermis, causing greater damage to the skin. Ultraviolet damage is the accumulation of damage from improper protection when exposed to ultraviolet light for extended periods of time. The external manifestations of uv damage are elevated skin temperature, formation of dandruff, itching, erythema, pigmentation, wrinkles, etc.; the intrinsic manifestations are sunburn cell formation, cellular DNA damage, increased free radical content, etc. The skin is stimulated by ultraviolet rays, and the skin aging is accelerated, and the process can be avoided and repaired. With the improvement of the consumption level of people, the outdoor activity frequency is gradually improved, the probability of ultraviolet injury to skin is greatly increased, and the efficacy cosmetic for repairing the ultraviolet injury becomes an indispensable product for consumers.

At present, a plurality of products for repairing ultraviolet injury exist in the market, and mainly relate to after-sun repair products. The after-sun repair product is designed mainly for the external manifestations of skin surface temperature rise, erythema, pigmentation, wrinkles and the like after ultraviolet injury, and mainly has the effects of physical cooling, relieving and calming and brightening the skin color. The skin care product is used in different steps, firstly, spray or facial mask is used for cooling the surface of the skin, then, the soothing and calming product is used for soothing the skin and relieving inflammation, and finally, the product containing the whitening component is used for brightening the skin color. The existing after-sun repair products cannot improve the immunity of cells to ultraviolet rays, and repair free radicals, cell DNA damage and the like caused by ultraviolet rays from deeper layers. Therefore, the problems of erythema, dull skin color, wrinkles and the like caused by ultraviolet ray damage cannot be fundamentally solved.

Disclosure of Invention

The invention aims to provide an active composition for repairing ultraviolet injury, which is added into a skin care product and can effectively reduce the formation of sunburn cells, inhibit the damage of ultraviolet rays to cell DNA and inhibit the increase of free radical content so as to improve the immunocompetence of cells to ultraviolet rays.
