U.S. Food and Drug Administration (FDA)-approved Restylane® injectable gel is a cosmetic filler made with hyaluronic acid (HA), a naturally occurring substance in the body. HA provides volume and elasticity to the skin, but its levels decrease with age, leading to loose skin and wrinkles. Restylane works by plumping the skin beneath lines and wrinkles, smoothing their appearance and making them less noticeable.

The most common treatment areas for Restylane are the glabellar lines (between the eyebrows) and the nasolabial folds (from the sides of the nose to the corners of the mouth). It is also FDA-approved for lip enhancement in individuals 21 years and older. According to the manufacturer, Medicis, results typically last up to 6 months before the hyaluronic acid is naturally absorbed by the body.

Benefits of Restylane Injectable Gel

Restylane effectively plumps glabellar lines and nasolabial folds, helping skin look younger and smoother. For lip enhancement, it adds fullness and definition.

Advantages of Restylane Injectable Gel

A key advantage of Restylane over other HA fillers is that it contains no animal-derived ingredients, eliminating the need for allergy testing, which can sometimes take weeks. Additionally, Restylane injections are quick—performed in-office by a medical professional in under 30 minutes—and require minimal to no downtime.

Side Effects of Restylane Injectable Gel

Common side effects include swelling, redness, pain, bruising, and tenderness at the injection sites, which usually resolve within a week. Though generally safe, Restylane carries risks such as infection, bleeding, or allergic reactions.
