Experience smooth and even skin that is free of lines, scars, and impurities with Europe's best-selling at-home dermaroller. The âme pure® CIT Face Roller smooths the surface of the skin with micro-fine needles. This creates tiny, invisible punctures in the top layer of the skin, which triggers the body's healing process and immediately activates the production of a blast of collagen and elastin. The skin's natural repair process helps fill in and smooth out wrinkles, fine lines and scars while also shrinking enlarged pores. The effect of the dermaroller is comparable to the effect of laser skin treatments. However, the dermaroller treatment can be performed on all skin tones without risk of hyperpigmentation because no heat is used.
