Microneedling pens are handheld devices used in skincare treatments to improve the appearance of the skin. They contain fine needles that create tiny punctures in the skin's surface, stimulating the body's natural healing process. This can enhance collagen and elastin production, leading to smoother and firmer skin. These pens are often used to treat various skin concerns, including acne scars, fine lines, and stretch marks. The procedure is minimally invasive and can be performed in a clinical setting by a trained professional. Recovery time is usually short, with most people experiencing only mild redness post-treatment.
