A lip switch, also known as a corner of the mouth lift, is a specialized surgical technique that works to correct the sagging corners of your mouth. Dr. Kaweski makes precise incisions along the borders of both lips. A portion of the lower lip tissue is then repositioned to lift the corner. Lip switch is performed under local anesthesia to ensure patient comfort. Although mild swelling and bruising may occur during recovery, these temporary effects gradually subside, revealing the final results.
