What is Derma Stamp? The Adjustable Derma Stamp smooths the surface of the skin with micro-fine needles made of surgical-grade stainless steel. This procedure creates tiny invisible punctures in the top layer of the skin, which triggers the bodys healing process and immediately activates the production of a blast of collagen and elastin. The skins natural repair process helps fill in and smooth out scars, fine lines and uneven texture while also shrinking enlarged pores. Adjustable needle length - The needle length you will use for the treatment will depend on how deep your acne scar or stretch mark runs, and which part of the body you are planning to use it on. Derma stamping is a good choice for when you want to even out your skins texture or to tone. Whether you have scar tissue on your back or shoulders or you simply want to get rid of acne marks on your cheeks and forehead, a derma stamp is a great alternative to a derma roller.
