What is Hyaluronic Acid?

Hyaluronic acid (Hyaluronan), also known as uronic acid and hyaluronic acid, is a large polysaccharide composed of two disaccharide units, D-glucuronic acid and N-acetylglucosamine. Unlike other mucopolysaccharides, it does not contain sulfur. Its hyaluronic acid molecules can carry 500 times more water and are recognized as the best moisturizing ingredient today. They are widely used in skin care products and cosmetics.

A large number of studies have shown that the moisture content of the human skin surface layer (stratum corneum) is about 15-30%. Values ​​lower or higher than this will make people uncomfortable, with a dry or greasy feeling. If this continues for a long time, the skin will become dry or chapped, causing the skin to lose elasticity, become rough and aged. After hyaluronic acid (HA) acts on the skin for internal conditioning, it can automatically adjust in different environments and always maintain the skin's moisture at 25-30%, keeping the skin moist and refreshed, making the skin more elastic, and playing a role in anti-wrinkle, delaying the aging of the entire skin, and beautifying the skin. Hyaluronic acid is one of the components of the human dermis. It has the ability to retain moisture at a level up to 100 times its own weight. Using skin care products containing hyaluronic acid HA can improve dry and wrinkled skin and restore its original smoothness and elasticity. Therefore, hyaluronic acid is the most ideal product for improving dry and aging skin.
