What are Derma Stamps? The Adjustable Derma Stamp uses micro-fine needles made of surgical-grade stainless steel to smooth the surface of the skin. The procedure creates tiny invisible punctures in the surface layer of the skin that trigger the body's healing process and immediately activate the production of massive amounts of collagen and elastin. The skin's natural repair process helps to fill and smooth the appearance of scars, fine lines and wrinkles. Uneven texture while shrinking enlarged pores.
