Lip augmentation creates fuller, plumper lips and reduces fine wrinkles around the mouth. Lips may be injected with collagen or with fat transferred from another site in the patient’s body. Both liquid collagen and fat are absorbed and repeat treatments are necessary to maintain results.
A natural or synthetic biocompatible material, or the patient’s own fat, is injected or implanted in the lips. One injection is usually sufficient to produce the desired result, which may be temporary, depending on the material used. Injections may need to be repeated periodically.
Allergic reactions can range from prolonged redness, swelling or itching, to firmness at the injection site. Other possible complications include bleeding, lip asymmetry, and migration and extrusion of the implant. Normal swelling and bruising lasts from three days to a week.
