Micro-needling is a minimally invasive cosmetic procedure that’s used to treat skin concerns via collagen production. Also known as collagen induction therapy, this treatment may help those looking to reduce the appearance of acne scars, stretch marks, reduce fine lines and wrinkles.

​

How does micro-needling work?

Micro-needling works by encouraging your skin to make more collagen. The idea is that pinpricks from the procedure cause slight injury to the skin and that the skin responds by making new collagen-rich tissue.

This new skin tissue is, in turn, more even in tone and texture. It’s normal for the skin to lose collagen via age or injury. By encouraging the skin to make new tissue, there may be more collagen to help make the skin firmer, too.
