Lip enlargement is accomplished in a multitude of ways. Some are more permanent than others. Lip improvement with the CO2 laser can remove fine lines and wrinkles around the mouth. Dermabrasion, chemical peels, collagen injections, and micro-fat injections can create significant improvements. In some cases more than one procedure may be needed to achieve the desired appearance. These procedures are usually performed on an outpatient basis. Recovery time depends upon the procedure performed.
