Restylane is a hyaluronic acid filler designed to add volume and smooth contours in areas like the lips and tear troughs. The filler is injected beneath the skin where it integrates with surrounding tissue, gradually absorbing over time. It works by attracting and retaining water, plumping the treated area and softening fine lines or hollows.

Restylane is suitable for adults looking to add lip fullness or fill in under-eye hollows. It works best for people with realistic expectations about temporary results and who are generally healthy. A provider will assess your anatomy and skin condition to determine if Restylane is appropriate for your goals.

The procedure takes 15 to 30 minutes depending on the area treated. A topical numbing cream is typically applied first, and many formulations of Restylane include lidocaine for added comfort. The provider uses a fine needle to inject small amounts of filler into predetermined areas.

Most people resume normal activities immediately. Mild swelling, redness, or bruising at injection sites is common and usually fades within a few days. Avoid strenuous exercise, excessive heat, and alcohol for 24 hours to minimize swelling.

Results appear gradually over 2 to 4 weeks as the filler settles and integrates. The lips or tear troughs look fuller and smoother. Results typically last 6 to 9 months, after which the body naturally absorbs the hyaluronic acid; touch-up treatments maintain the effect.
