The role of hyaluronic acid:

Hyaluronic acid mainly exists in the dermis of human skin in the form of colloid, which is mainly responsible for storing water, increasing skin volume and making skin look full, rich and elastic, so hyaluronic acid has a good moisturizing effect. However, hyaluronic acid in the human body will gradually disappear with the increase of age, which will make the skin lose its water storage capacity, gradually become dull and aging, and form fine wrinkles.
2. Anti-aging
HA hyaluronic acid is widely distributed in human connective tissue and exists almost in pure state in vitreous body and joint cavity. Hyaluronic acid in skin has a good effect on metabolism. If HA in the skin is destroyed, the skin will lose moisture and elasticity, so HA is a good anti-aging factor.

Hyaluronic acid can also be used for rhinoplasty and chin pad.
4, improve the ability of wound healing

Hyaluronic acid should be used aseptically, limited to 1 time. Do not use hyaluronic acid gel after it is damaged.
