Microneedling uses a fine needle to create microwounds, or channels, in the skin. This triggers the production of capillaries, elastin, and collagen. It’s also called skin needling or collagen induction therapy.

If the procedure also uses radiofrequency waves, it’s called radiofrequency microneedling. The needle releases radiofrequency into the channels, causing additional damage. This enhances the effects of standard microneedling. The skin that grows back is thicker and smoother.
