Microneedling is a minimally invasive collagen-induction treatment to repair and rejuvenate the skin. A microneedling pen with tiny needles creates micro-injuries in the top layer of the skin, which triggers the body to repair itself and create new collagen and elastin. Microneedling improves texture and firmness, as well as aiding in scar reduction, minimizing pore size, and reducing the appearance of stretch marks.
