A kind of eye skin care composition containing hirudin and hyaluronic acid

Abstract

The invention provides an eye skin care composition containing hirudin and hyaluronic substances, which is composed of hirudin and hyaluronic substances, and the mass ratio of hirudin and hyaluronic substances is 1:1 -20. The molecular weight of described hyaluronic acid substance is 1.5×10 5 Da‑1.8×10 6 Da. The eye skin care composition can be used in cosmetics, and the content in cosmetics is 0.01-10%. In the present invention, hyaluronic acid substances with specific molecular weight have synergistic effect on hirudin. The combination of the two substances can solve the problems of dark circles, edema, eye bags, fine lines and dry lines and fat particles in the eye skin.

Description

technical field [0001] The invention belongs to the field of cosmetics, in particular to an eye skin care composition containing hirudin and hyaluronic acid substances. Background technique [0002] The eye skin is the thinnest part of the human skin, only about 1 / 4 of the thickness of the facial skin, so it is vulnerable to damage from the external environment such as ultraviolet rays; at the same time, the eye skin is rich in connective tissue, rich in capillaries and nerve endings , the walls of these capillaries are very thin and have a certain degree of permeability, so they are easy to congest and cause eye edema due to water accumulation; in addition, the eye skin lacks the distribution of sebaceous glands and sweat glands, and the oil that can be supplied is relatively small, and the skin has no natural Moisturizing ability, so it is more prone to dryness and lack of moisture than other parts of the skin, resulting in dry lines and fine lines on the skin around the e...
