Collagen induction therapy

Common card · No. 411416

Collagen induction therapy (CIT), also known as microneedling, dermarolling, or skin needling, is a cosmetic procedure that involves repeatedly puncturing the skin with tiny, sterile needles (microneedling the skin). It is important to distinguish CIT from other contexts in which microneedling devices are used on the skin (e.g., transdermal drug delivery, vaccination). It is a technique for which research is ongoing, but has been used for a number of skin problems including scarring and acne. Some studies have also shown that when combined with minoxidil treatment, microneedling is able to treat hair loss more effectively than minoxidil treatment alone.
