Microneedling with the SkinPen is a minimally invasive cosmetic procedure that uses very fine needles to create hundreds of tiny, controlled injuries in the skin. This triggers the body's natural wound healing process, prompting it to produce new collagen and elastin. The SkinPen's precise, automated, multi-speed, and adjustable needles allow for customized treatments to improve the appearance of acne scars, fine lines, wrinkles, hyperpigmentation, stretch marks, and other skin concerns on the face and body. Treatments typically cause some temporary redness and swelling, but require little downtime compared to more invasive procedures. Multiple sessions are usually recommended for optimal results as the skin's rejuvenation process takes time. Proper aftercare is important to maximize results and allow the micro-injuries to fully heal.
