Sublative Skin Resurfacing is the only skin resurfacing technology proven to reduce moderate to severe acne scars, fine lines, skin texture and irregularities. This radiofrequency treatment leaves tiny little microscopic needle holes in the skin that rejuvenate the collagen as the skin heals. The skin can look red and slightly irritated for a few days up to a week. After it has healed, you will have fresher looking skin. A series of 3 will give you the most dramatic result for a youthful appearance and change in your skin.
