Abstract
Skin needling, percutaneous collagen induction (PCI), collagen induction therapy (CIT), dry tattooing, needle dermabrasion, intradermabrasion, dermal remodeling, multitrepannic collagen actuation, intradermabrasion (MCA), these are all names for the same treatment. Skin needling is a procedure that involves using a sterile roller comprised of a series of fine, sharp needles to puncture the skin. Performed under local anesthetic with sedation, the device is “rolled” over the surface affected by acne scars to create many microscopic channels deep into the dermis of the skin, which is stimulated to produce new collagen. Skin needling is a procedure that ensures better results if it is associated with alpha-hydroxy acids (AHAs) treatment.
