faceDescription: A hyaluronic acid filler used to volumize and slightly lift sagging areas of skin. It can also be used to plump lips.

How it’s done: Restylane is injected into the areas that you and your doctor have determined need voluminizing. Depending on how many areas you’re having treated, the treatment can take up to an hour, and the results can last up to six months. Like all hyaluronic acid fillers, the results fade gradually for a more natural appearance, and have collagen boosting effects.

Complications: Swelling, redness, pain, itching, discolouration and tenderness at the injection site can occur.

Recovery: Most people are fine immediately after treatment, but side effects can persist for up to a week, though they usually go away on their own.

Cost: $500 to $750 per injection, though it depends on the clinic.
