At W Cosmetic Surgery, microneedling is a great technique and treatment that uses a pen that roles tiny needles over the skin. That triggers your skin's healing, natural healing response, to then build collagen under the skin. The Dermapen is brand new to us. It's an electronic device and it has needles attached to it. The great thing about it is I can adjust the length. So I can do different areas of your face at different lengths.
