Micro-needling, also called Collagen Induction Therapy, involves the use of a tool, called a Dermapen. The pen has small needles that make miniature holes in the top layers of the skin. This process triggers the skin to heal itself, stimulating collagen and elastin in the skin. Collagen is a protein that is important for protein, allows for skin to bounce back after being stretched. Micro-needling improves the appearance of fine lines, wrinkle, pores, and scars.
