(Percutaneous Induction Needling, also referred to as PCIT, Percutaneous Collagen Induction Therapy… a.k.a. micro-needling, or automated micro-needling) P.I.N. is a method of introducing a controlled wound into the skin triggering a release of natural growth factors, new collagen & elastin. This process causes much less damage to the epidermis than dermal rolling or lasers and other ablative treatments, which helps to protect the new skin cell growth providing for quicker healing and a much higher success rate for overall and longer lasting results.
