Collagen Induction Therapy (CIT) also known as micro-needling, skin needling or dermal needling, is a procedure that involves the use of micro-fine stainless needles that are pressed into the skin, to create a controlled skin injury. In response to the micro injuries, your body releases growth factors and cytokines, which trigger the wound-healing process stimulating the skin’s natural ability to repair itself. This results in new cell stimulation, natural collagen formation and an increase in the blood flow to the skin.
