Naturally present in the skin, hyaluronic acid maintains its hydration levels and contributes to its tone. It is a potent moisturising agent with a capacity to retain up to 1,000 times its weight in water.
The amount of hyaluronic acid in the dermis gradually decreases with age. As a result, the skin becomes dry and fragile and the first wrinkles appear. When it is injected into the dermis, Teosyal effectively compensates for this deficiency due to its high hyaluronic acid concentration.
