Microneedling (also known as collagen induction therapy) is a minimally invasive skin rejuvenation procedure that involves the use of fine needles to create tiny punctures in the top layer of skin. This triggers the body’s natural healing process, which results in the production of new collagen and elastin. Microneedling can be used to improve the appearance of fine lines, wrinkles, acne scars, and other types of scarring. It can also be used to improve the overall texture and tone of the skin.
