A Diamond Peel is a crystal-free microdermabrasion. During this procedure, a state-of-the-art diamond tipped hand piece will be used to gently remove the dead cells and debris on the outer layer of your skin, leaving smoother, cleaner, brighter skin.Radiofrequency (RF) therapy, also called radiofrequency skin tightening, is a nonsurgical method of tightening your skin. The procedure involves using energy waves to heat the deep layer of your skin known as your dermis. This heat stimulates the production of collagen.
