Hyaluronic acid is a natural substance found in the human body and has significant benefits but, unfortunately, its production decreases overtime. It is a humectant capable of retaining as much as 1000 times its weight in water in order to restore skin’s volume. Hyaluronic acid is produced by skin’s fibroblasts, however as its production decreases and its quantity is reduced, fine lines and wrinkles begin to appear on the skin. Over the last years therapies with injectable hyaluronic acid have become extremely popular over the last years. They are very safe and their goal is to restore the loss of hyaluronic acid in the skin in order to diminish wrinkles and fine lines and make it look fresh, elastic and bright again.
