The effect of microneedling depends on various factors, such as skin thickness and the extent of scars and wrinkles. Usually, a single treatment is enough to achieve visible results. The small swelling caused by the microstitches makes the skin look firmer and plumper immediately after the treatment. In the weeks that follow, the results "crystallize": larger pores become smaller and the skin texture refines. The production of collagen, hyaluronic acid and elastin is stimulated and the freshness effect fully unfolds.
