Most people lose fat and the small saliva glands of the lips as they age; the lips begin to thin and turn inward, showing less pink.

The reduced bulk of the lips also makes the small vertical lines radiating outward from the lips worsen, and although these are mainly from environmental damage such as sun, wind, and smoking, the loss of bulk contributes to their occurrence. Adding bulk to the lips with cosmetic surgery helps to break the skin attachment to the underlying muscle and reduces these lines without the side effects of layering or chemical peeling. Dr. Gelfant often uses some of the fat and fibrous tissue removed from the SMAS to plump the lips through tiny incisions in the corners of the mouth. These heal almost without a trace.
