Restylane is a brand of hyaluronic acid (HA) dermal fillers designed to treat various cosmetic concerns. It is used to correct fine lines and wrinkles, sunken and hollowed skin, and contour areas like the chin and jawline. 

Restylane replenishes the skin's natural hyaluronic acid (HA), providing hydration and a more youthful, plump appearance. This gel is injected to add volume, smooth lines and wrinkles, and sculpt facial contours. Its formulation mimics the body's natural HA for seamless, natural-looking enhancements.

The longevity of Restylane fillers depends on a variety of factors, including the treatment area, the amount injected, and the client’s metabolism. Results will typically last between six and 12 months before the filler naturally dissolves within the skin.

To maintain optimal results, maintenance treatments every six to 12 months are recommended. 

Restylane is FDA-approved, meaning it has undergone rigorous testing and evaluation by the U.S. Food and Drug Administration to ensure its safety and efficacy for its intended use. It is widely used by professionals around the world, boasting over 25 years of clinically proven safety.
