Microneedling, also known as collagen induction therapy, is a minimally invasive skin rejuvenation procedure that helps minimize the signs of aging, improve the appearance of acne scars and rejuvenate aging skin. The microneedling device causes controlled micro-injuries that stimulate the body’s natural wound healing process. The micro-injuries trigger the release of cytokines and growth factors that lead to remodeling of collagen and elastin.
