The AcuLift™ Dermal Roller (a collagen induction therapy) can help treat signs of aging (such as fine lines and wrinkles), tighten loose skin, reduce acne scars and stretch marks, smooth cellulite, and help reduce hair loss. And when used before applying topical lotions or hair loss products, the effectiveness of these products is greatly increased. The AcuLift™ Roller offers a safe alternative to ablative treatments such as laser resurfacing, chemical peels or dermabrasion, or non-ablative treatments such as IPL™, Fraxel™, or CO2 laser. It provides a non-invasive, easy-to-use and affordable way to improve the appearance of skin or hair. The AcuLift™ Dermal Roller comes in a clear plastic case that can be used as storage in between uses. Each roller measures 5.25″ l x 1.5″ h tapering to 1″ and is contoured to fit nicely in the hand. The roller itself has a diameter of 0.75″ and contains 540 micro needles, that are either 0.5mm or 1.0mm in length.
