We use the Collagen P.I.N. due to its ease of use and ability to avoid cross contamination between patients. A sterile disposable needle tip is used with each patient, avoiding cross contamination. The Collagen P.I.N. is awaiting FDA clearance  for the treatment of scarring. Micro-needling has been successfully used for the treatment of acne scars, wrinkles, photoaging, and melasma.
