What Does Hyaluronic Acid Do to Your Skin?
Hyaluronic acid is an acidic mucopolysaccharide. In 1934, Professors of Ophthalmology at Columbia University in USA first isolated the substance from bovine vitreous body.
Hyaluronic acid shows many important physiological functions in the body with its unique molecular structure, physical and chemical properties, such as lubricating joints, regulating the permeability of blood vessel wall, regulating protein, diffusion and operation of water and electrolytes, and promoting wound healing.
It is particularly important that hyaluronic acid has a special water retention effect, which is the best moisturizing substance found in nature and is known as the ideal natural moisturizing factor. Hyaluronic acid is a multifunctional substrate widely distributed in all parts of the human body.
The skin also contains a lot of hyaluronic acid. The maturation and aging process of human skin also changes with the content of hyaluronic acid and metabolism. It can improve skin nutrition metabolism, make skin tender, smooth, wrinkle, increase elasticity, prevent senescence, and be a good transdermal absorption enhancer at the same time of moisturizing. In combination with other nutrients, it can play a more ideal role in promoting nutrient absorption.
But now a lot of cosmetics will propagate the hyaluronic acid in the product. In fact, the content is very small, and the size of the molecule is relatively large, and it is almost not absorbed by the skin. Skin care products containing hyaluronic acid can only play a moisturizing role on the skin. If the skin itself is short of water, the use of cosmetics containing hyaluronic acid will not play a role of replenishment.
