Skin needling (also known as Collagen Induction Therapy (CIT) and dermal rolling) originates from ancient acupuncture techniques, developed in the early 1990s by a team of plastic surgeons, medical engineers and dermatologists. Skin-Inject DNC Derma Roller is a non-invasive procedure utilising small rolling discs containing microscopic needles between 0.25mm to 1.55mm. Tiny puncture channels are created within the epidermis and dermis to encourage an organic renewal and regenerating response. No injections, incisions, stitches or implants. Treat acne scarring, enlarged pores, anti-aging.
