What was the first FDA-approved hyaluronic acid for dermal filling?

Restylane was the first hyaluronic acid filler to receive approval from the FDA for use in dermal filling. It was introduced in the late 1990s and has since been widely utilized in cosmetic procedures for facial volumization and wrinkle reduction. The significance of its approval lies in its pioneering role in establishing hyaluronic acid as a safe and effective material for dermal fillers.

Hyaluronic acid is naturally present in the body, which helps to minimize the risk of adverse reactions and makes it a favorable choice for enhancing facial aesthetics. Restylane's approval set the stage for the development of many other hyaluronic acid-based fillers, leading to a diverse range of products, but it remains a cornerstone in the field of aesthetic medicine.
