Restylane® Injectable Gel
U.S. Food and Drug Administration (FDA)-approved Restylane® injectable gel is a cosmetic “filler” that contains hyaluronic acid (HA), a natural substance that is found in the body. HA gives volume and elasticity to the skin, but as the body ages, HA levels decrease, resulting in loose skin and wrinkling. When injected, Restylane® gel is designed to plump the skin beneath lines and wrinkles, smoothing them out and making them less noticeable.
The most common areas for Restylane® treatment are the glabellar lines (which run between the eyebrows) and the nasolabial folds (which run from the sides of the nose to the corners of the mouth). Restylane® injectable gel is also FDA-approved, for those 21 and older, for enhancing the lips. According to manufacturer Medicis, results can last for up to 6 months, at which point the hyaluronic acid is reabsorbed by the body.
