Composition and cosmetic for double moisturizing, repairing and improving skin elasticity

Abstract

The invention discloses a composition and cosmetic for double moisturizing, repairing and improving skin elasticity. The composition for double moisturizing, repairing and improving the skin elasticity is prepared from the following raw materials in parts by weight: 0.5-5 parts of oat beta-glucan, 1-10 parts of a bifidus yeast fermentation product lysate, 0.05- 0.5 part of hydrolyzed sodium hyaluronate and 0.1-1 part of hydrolyzed collagen, wherein the molecular weight of the hydrolyzed sodium hyaluronate is 5000 to 10000 Da, and the molecular weight of the hydrolyzed collagen is less than 3000Da. The multiple components of the composition supplement each other and promote each other, and the composition has the double moisturizing and repairing functions of stratum corneum layers and corium layers; in formula application, skin conditioners or moisturizers such as glycerinum and butanediol do not need to be additionally added except for necessary thickening agents, preservatives and essence compared with single stratum corneum moisturizing or single corium layer moisturizing, the moisturizing and repairing effects are more remarkable, and the effect of improving the skin elasticity is more effective.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, in particular to a composition and cosmetics for double moisturizing, repairing and improving skin elasticity. Background technique [0002] Human skin consists of three parts: epidermis, dermis and subcutaneous tissue. Dry, rough, flaky, shriveled and lacking elasticity of the skin are all external manifestations of dehydration of human skin. The factors that lead to dehydration of the skin are mainly in the epidermis and dermis of the skin. [0003] The stratum corneum exists in the outermost layer of the epidermis of the skin, and its water content is generally about 25%. It is the first protective barrier of the skin. Excessive cleaning of the stratum corneum will lead to excessive loss of sebum; excessive hydration of the skin caused by frequent mask application, thinning of the stratum corneum caused by frequent exfoliation, and long-term exposure to ultraviolet rays will reduce the imm...

AI Technical Summary

Problems solved by technology

There are also some oily moisturizing ingredients, which form an airtight closed film on the skin surface, which can only prevent the skin from losing moisture in the short term, but cannot effectively increase the moisture content of the skin, and some people will also have oily skin, acne and other problems.

The above-mentioned moisturizing ingredients have a single mechanism of action, do not fundamentally play a role in repairing the skin barrier, and do not solve the problem of the reduction of sodium hyaluronate, collagen and elastin in the dermis. Water storage capacity, recovery of skin elasticity, etc. are very limited, so it is difficult to achieve long-term moisturizing effect
