is very common surgery nowadays. 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. 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. Fat injection to the lower lip must be more than the upper lip since the lower lip normally 2mm will rise above the upper lip.
Collagen injections have a short-lived effect (9-12 weeks) but fat injections provide longer-lasting results. Immediate return to normal activities (one-day return if sedated) for nonsurgical procedures; depending on the procedure and materials used, recovery period is within a week for surgical procedures.
