Restylane

Restylane is a comprehensive line of injectable dermal fillers composed of hyaluronic acid, a naturally occurring polysaccharide that provides structural support and hydration to the skin. Originally developed by the Swedish biotechnology company Q-Med (now a subsidiary of Galderma), Restylane was the first stabilized hyaluronic acid filler to receive FDA approval in 2003. The product line utilizes two primary manufacturing technologies: **NASHA** (Non-Animal Stabilized Hyaluronic Acid), which creates a firmer gel for precision lifting and contouring, and **XpresHAn Technology** (also known as Optimal Balance Technology), which produces a more flexible gel designed for natural-looking results in dynamic areas of the face. Restylane is indicated for the correction of moderate-to-severe facial wrinkles and folds (such as nasolabial folds), lip augmentation, cheek enhancement, and the restoration of volume in the midface and back of the hands.
