What is microneedling? January 24, 2023 Microneedling is a minimally invasive cosmetic treatment used to rejuvenate the skin by boosting the body’s natural production of collagen. At Heights Plastic Surgery, we use the SkinPen® microneedling device which is fitted with several very small, hair-like needles that, when pressed into the skin, create very small injuries called microchannels. These microchannels trigger your body’s natural healing processes which boost collagen production to smooth away fine lines and wrinkles, minimize pore size, reduce acne scarring, and even tighten loose and sagging skin around the face. The SkinPen® is the first FDA-approved microneedling device proven to safely and effectively treat acne scarring in patients 22 and older.
