The mechanism of Dermaroller’s action is based on Collagen Induction Therapy, a treatment which aims to restore youth and smoothness to your skin by stimulating the natural production of a substance called collagen. The micro needles create small channels into the deep layers of the skin which break up the old collagen strands, and stimulate the creation of new ones. Collagen is an important material responsible for keeping your skin tight firm and young.
Although Micro-Needling may look a little aggressive with its needles, it is actually much gentler than you may think. This is because; Micro-Needling does not harm the epidermis -the very top layer of skin. As the small handheld roller with its micro needles is gently rolled over the area being treated, it creates pin point punctures. The pores of the top layer of the skin are parted without being damaged, leaving the epidermis, intact. The procedure usually requires the application of anesthetic cream which is effective after 30min.
Some reddening is typical after treatment but the downtime is very quick and you should have recovered after 2 days.
