In addition to diet and exercise, a good weight-loss plan should include ways to treat your skin as your aesthetic needs change. “Skin care is an essential aspect of any rejuvenation plan. Topicals such as retinols and aesthetician services like intense pulse light (IPL) for skin tightening, tone, and texture are a must,” says Dr. Wise. "Look for products that contain an antioxidant or growth factors to help plump up dehydrated and dull skin," adds Dr. Nichols.
