Microneedling treatments rejuvenate skin by reducing scars and signs of aging and also enhancing product absorption, according to a presenter at South Beach Symposium.

Microneedle rollers contain fine needles that roll over the skin and create micro-wounds that stimulate the body’s healing process, increasing the growth of new collagen fibers and permitting penetration to damaged layers of the skin that other treatments cannot reach, Glynis Ablon, MD, FAAD, of the Ablon Skin Institute, said during her presentation.
