Microneedling is a minimally invasive procedure that stimulates collagen production in the skin. The procedure is sometimes also known as collagen induction therapy which can treat wrinkles, oversize pours, stretch marks, scars including acne scars, and skin damaged by sun. 

Microneedling involves the the inserting of short, very fine needles into the skin. The procedure does not actually involve injections, but the needles lightly probe the skin piercing it just enough to induce the healing process and stimulate the production of skin tissue and collagen. 

Because the minimally invasive nature of the procedure, there is no real recovery time so normal activites can usually resume immediately.
