Problems solved by technology

Even for products that have been developed and marketed, there is still a lack of deeper research, which is not conducive to the promotion of products
In addition, different extraction methods, extraction parts, and growth environments of plants have large differences in their components, which is not conducive to unified and standardized production. The safety and stability of different plants and the compatibility between plants and traditional sunscreens need further research.

Abstract

The invention belongs to the field of daily chemicals, and particularly relates to a skin-care composition with a sunscreen effect as well as a preparation method and application thereof. The skin-care composition, provided by the invention, comprises the following components: a natural plant extract, palmitoyl tetrapeptide-7, vitamin E, oryzanol and oligomeric proanthocyanidin, wherein the natural plant extract contains a variety of natural plant sunscreen extracts, has a very good overall effect of absorbing ultraviolet light, scavenging free radicals, inhibiting generation of melanin, inhibiting release of allergy mediators, protecting fibroblasts, inhibiting the activity of matrix metalloproteinase and the like, and has a very good sunscreen effect; the oligomeric proanthocyanidin can be used as a protective agent for the oryzanol and the vitamin E, is free of skin irritation, has an antioxidant protective effect on skin, and can improve the skin-care and sunscreen effect of the composition.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and in particular relates to a skin care composition with sunscreen effect and its preparation method and application. Background technique [0002] In recent years, a large amount of fluoride gas represented by Freon has been emitted, and the atmospheric ozone layer has been irreversibly damaged, thereby weakening the ozone layer's ability to filter and block ultraviolet rays. Scientific studies have shown that the destruction of the ozone layer is one of the main reasons for the rising incidence of human skin cancer. Because ultraviolet radiation will change the structure and function of cell components, when the cells are saturated with ultraviolet radiation, the cells will lose the ability to communicate with other cells and undergo apoptosis. Therefore, protecting the skin against ultraviolet radiation is an effective measure to prevent skin cancer. The ultraviolet radiation that causes dama...
