This evolving technique uses an electronic device to create controlled channels or microwounds into the skin. These micro-passages stimulate the normal wound healing cascade by releasing growth factors, leading to the production of new collagen, elastin, and microscopic blood vessels (capillaries). The micro-channels may also be used to aid delivery of cosmeceuticals, growth factors, and bioactive peptides into the dermis. Microneedling has many uses, including improving scars (acne scars, surgical scars), reducing stretch marks, improving fine lines, and helping create more even skin pigmentation. Unlike laser treatments and deep chemical peels, microneedling causes minimal injury to the skin.
This makes microneedling a versatile technique, being able to treat areas that lasers cannot like the neck, chest, and hands.
