Problems solved by technology

The invention can absorb ultraviolet rays, but the sunscreen effect applied in cosmetics is poor, and the absorption effect on blue light is also weak
[0007] To sum up, the existing natural plant sunscreen skin care products have limitations in efficacy, and some only focus on the protection of ultraviolet rays, or only have the effect of anti-blue light and sunscreen synergistic effect, and they are not only effective in improving the skin's own protection. Less effective in repair and resistance

Abstract

The invention provides a light-protective plant composition and a preparation method and application thereof. The preparation raw materials of the plant composition comprise peony flowers, wintersweetflowers, saffron, centella asiatica, cassia twigs and cocoa seeds. Active components of the light-protective plant composition mutually cooperate, so that the light-protective plant composition has synergistic effects, and protection range covers UVB, UVA and HEV wave length regions. The composition disclosed by the invention not only can perform light protection through absorbing ultraviolet rays but also can eliminate massive active oxygen free radicals generated under inducing of blue laser, and can improve the capacity of skin for withstanding harmful rays from external world through improving the intrinsic immunity and repair force of the skin.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a plant composition and its preparation method and application, in particular to a photoprotective plant composition and its preparation method and application. Background technique [0002] High Energy Visible (HEV) is a region with a wavelength between 400-500nm, which comes from sunlight, electronic products, artificial light sources, etc. In modern society, people use electronic products, including mobile phones, computers, etc. more and more frequently, and the problem of blue light pollution is becoming more and more serious. With the in-depth research on the damage of light to skin, people gradually realize that not only ultraviolet rays can cause damage to human skin, but also Moreover, high-energy blue light (HEV) can also cause damage to human skin. Scientific research shows that blue light can stimulate the generation of active oxygen free radicals, thereby causing...
