Anti-oxidative-activity oligopeptide and sun-screening agent combined emulsion

Abstract

The invention provides an anti-oxidative-activity oligopeptide and sun-screening agent combined emulsion. A cosmetic comprises the following components in percentage by weight: 0.1-20% of biologically active peptide and 1-30% of a sun-screening agent, wherein the biologically active peptide comprises dipeptide and tripeptide with antioxidant activity, dipeptide is carnosine, and tripeptide is one or more of glutathione, synthesized tripeptide phenylalanine-lysine-leucine and collagen tripeptide. According to the anti-oxidative-activity oligopeptide and sun-screening agent combined emulsion provided by the invention, dipeptide and tripeptide with the antioxidant activity are combined to be taken as the biologically active peptide for removing free radicals in the body, and the biologically active peptide is effectively combined with the non-biologically-active sun-screening agent to ensure that the skins can be protected from ultraviolet radiation and the damages of the free radicals to the skins can be eliminated.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to an emulsion in which an antioxidant active oligopeptide is used in combination with a sunscreen. Background technique [0002] When the skin is exposed to excessive ultraviolet rays, it will damage the epidermal cells; activate tyrosinase, accelerate pigment synthesis, destroy the skin's moisturizing function, make the skin dry, damage the elastic fibers in the dermis, and cause fine lines. Under strong exposure, it can also cause skin inflammation and burns. When there are abnormalities, it will become pigmented skin cancer, etc. [0003] At present, there are many types of sunscreens on the market, which are mainly reflected in the sunscreen function. They are generally used outside, but they are not suitable for use indoors, because ordinary sunscreens have no moisturizing and maintenance effects on the skin, and the application time is too long, which will increase the Loads and ma...
