Microneedling, also known as collagen induction therapy, is a minimally invasive procedure used for skin rejuvenation. During treatment, a pen-like device studded with tiny needles are used to make precise, microscopic punctures in the skin. The tiny wounds do not leave scars but instead trigger the skin’s repair mechanism, stimulating collagen production. Microneedling is commonly used to treat scars, enlarged pores, fine lines and wrinkles, as well as stretch marks. Microneedling can also be used to help topical treatments penetrate the skin more effectively.
