Collagen is the most common protein in your body. It creates the framework of your skin and gives your skin its firmness.

As you age, your cells produce less collagen, which leads to sagging skin and wrinkles. Skin laxity starts to occur around the ages of 35 to 40 when the quantity and quality of your collagen begins to decline.

Radiofrequency (RF) therapy, also called radiofrequency skin tightening, is a nonsurgical method of tightening your skin.

How does it work?

• The procedure involves using energy waves to heat the deep layer of your skin known as your dermis. RF waves heat the deep layer of your skin to between 122 and 167°F (50–75°C). This heat stimulates the production of collagen.

• The procedure normally takes about half an hour and is nearly painless.

The primary benefits of RF therapy are tightening your skin and getting rid of wrinkles. RF therapy may also help fight sun damage due to its ability stimulate the production of collagen.
