Blue LEd Derma Roller .25. Using 200 extremely fine needles, which penetrate the skin just enough to stimulate collagen and elastin production. This leads to the thickening of the skin and smoothing of wrinkles and scars. The resulting micro-channels that are opened in the skin due to the needle action also help in increasing the absorption of serums and topical creams used in one's daily beauty routine. This leads to significant improvement in skin penetration and increased overall efficacy of skin care products. The Roller leaves the epidermal barrier fully intact, and the micro-channels created by the 200 fine needles fully close within just a few hours after initial application. This provides just enough time for new collagen structures to form within the skin's lower layers, but short enough to ensure the patient can quickly resume normal schedules.
