Microneedling is the process of applying a roller or pen-type device tipped with rows of tiny needles to the skin in order to create thousands of holes in the epidermis to increase the efficacy of skincare products and to stimulate growth factors and collagen production within the skin. Microneedling’s wound healing response also helps address surface skin and textural problems such as wrinkles, stretch marks, acne scars, large pores.
