A Dermaroller is a skincare tool featuring a handle and a roller covered with tiny needles. It is used in a process called microneedling, which creates micro-injuries in the skin to stimulate collagen production. This can help improve the appearance of scars, fine lines, and overall skin texture. The procedure can be performed at home or by a professional. When used correctly, a Dermaroller can enhance the absorption of skincare products, making them more effective. It's important to maintain proper hygiene and follow guidelines to minimize the risk of infection or skin irritation.
