Skin needling is also called micro-needling therapy or collagen induction therapy. It is a minimally-invasive and non-surgical procedure for facial rejuvenation that involves the use of a micro-needling device to create controlled skin injury.
As each fine needle punctures the skin, it creates a channel or micro-wound. The controlled injury triggers the body to fill these micro-wounds by producing new collagen and elastin in the papillary dermis. In addition, new capillaries are formed. This leads to reduction of scars and skin rejuvenation, i.e., improved skin texture, firmness and hydration.
