Collagen in the skin becomes depleted or damaged over time. The result is visible signs of aging such as thinner or loose skin and wrinkles. Thermage treatments provides skin tightening without surgery, with no downtime, and with very minimal risk. Thermage uses radiofrequency energy to heat the skin, tightening the collagen and giving a smoother, lifted look to the skin. The treatments are performed in the doctor's office and no anesthesia is needed. There may be some discomfort during the treatment in certain areas. Some people have redness or swelling after the treatment, which usually disappears within 24 hours. Most people go right back to work or resume their regular social activities after treatment.
