Dermal fillers are a popular injectable treatment used for multiple aesthetic goals, from reducing wrinkles to restoring facial volume or reshaping features. Hyaluronic acid (HA) is a common type of dermal filler, with Restylane fillers utilizing HA gel technology. The HA used in Restylane fillers is made of transparent, naturally occurring sugars found in the skin that provide hydration, fullness, and elasticity. With these qualities, Restylane fillers are a safe and effective resource to help patients achieve their desired aesthetic results.
