1. Hydrating and moisturizing: The main function of hyaluronic acid is hydrating and moisturizing, which mainly exists in the dermal layer of skin in the form of colloid. However, with the increase of people's age, the hyaluronic acid in the body will gradually decrease, so the moisturizing ability of the skin will gradually decrease with the increase of people's age, so many people will supplement hyaluronic acid to the skin through skin care products or injections. Because when there is less or no hyaluronic acid in the skin, the skin will become dry, dull and even have small fine lines because of the loss of water.

2. Anti-aging: Hyaluronic acid can lock the moisture in the skin and has very good moisturizing and water storage functions. It can not only keep the skin elasticity of the skin, but also play a good role in lubricating the skin tissue, thus keeping the skin young and elastic. With the loss of hyaluronic acid, the skin becomes dehydrated and loses elasticity, so the skin begins to age at night. Here, one of the functions of hyaluronic acid is to delay aging.

3. Anti-inflammatory and healing-promoting effects: Hyaluronic acid is also the main matrix component in the skin. Its function is to help water enter the intercellular space, so that water and tuberculosis in protein form protein gel, which can help protect cells from invasion by pathogenic bacteria. If there is a wound, it can promote the healing of skin wounds and has a very good anti-inflammatory effect. Therefore, hyaluronic acid is also used in some surgical operations in medicine. The above is an introduction to the role of hyaluronic acid. After reading the above, I believe that everyone should have a certain understanding of the role of hyaluronic acid. The above introduction hopes to help everyone.
