Microneedling is a minimally invasive way to stimulate the production of new collagen; it is a favorite among patients and clinicians alike for its ability to achieve astonishing anti-aging results in a safe and effective manner. Rejuvapen microneedling is the name of a specific microneedling device that uses a small pen-like implement to create micro-wounds in the skin using ultra-thin needles. The device is FDA-approved and uses safe, medical-grade microneedling products to treat a variety of skin conditions, including acne, cellulite, wrinkles, and fine lines. Rejuvapen microneedling is a non-invasive skin treatment that uses tiny needles to stimulate the skin, improve the appearance of fine lines and wrinkles, and enhance skin tone and texture. The treatment is designed to improve the appearance of the skin from the inside out by increasing collagen production, which is why it is also referred to as Collagen Induction Therapy (CIT). The treatment is fast, and effective, and patients often see results in as little as a few weeks.
