Hyaluronic Acid

In humans, hyaluronic acid is most abundant in the skin, accounting for 50% of the total body hyaluronic acid. Hyaluronic acid is present in many cosmetic formulations and some literature highlights its benefits when used topically in dermatological practice. Results from several trials generally support that HA‐based cosmeceuticals are effective solution for improving skin hydration, rejuvenation, and healing.
