HA is a natural sugar found in the human body, hyaluronic acid is the most hydrating substance in the world. It’s primary function is to attract water and keep the skin hydrated, plump and youthful. The human body creates Hyaluronic Acid naturally, so it is impossible to be allergic to it. As we age, our body decreases the amount of HA produced as well as collagen fibers. This decrease causes our body to look older, resulting in loss of hydration and elasticity; therefore wrinkles form and the skin begins to sag. By adding HA into the skin we revive the collagen and promote a fresher, plumper look. Hyaluronic Acid is also the main structural element of connective tissue.
