Microneedling uses a hand-held device that slides across the skin, creating tiny microscopic holes in the upper layers of the skin. The process creates a wound response, triggering the creation of new collagen and elastin fibers. The result is smoother, firmer, and youngerlooking skin. It can be used to treat hyper-pigmentation, hypo-pigmentation, and acne scars. Patients may benefit more from a series of skin care treatments spaced six to eight weeks apart.
