A manual device designed to be rolled over the skin to create high-density minute skin punctures to stimulate tissue regeneration and improve the appearance of the skin. It is a hand-operated cylindrical roller, studded with rows of short micro-needles, that rotates around an axle attached to a handle. Also known as micro-needling, this skin treatment technique is used for skin rejuvenation, collagen induction therapy (CIT), to treat stretch marks, acne scarring, hyperpigmentation, wrinkles, and for hair loss therapy. It is normally available [non-prescription] over-the-counter (OTC) for home or professional use. This is a reusable device.
