A derma roller is a small handheld device with a rolling drum covered in fine needles. It is typically used to create micro-injuries in the skin in order to stimulate the production of collagen and elastin. It is often used to improve the appearance of acne scars, fine lines, and other skin imperfections. Derma rolling can be performed at home, although it is recommended to be done by a trained professional to minimize the risk of injury or infection. It is important to properly sterilize the device and follow the recommended usage instructions to minimize the risk of adverse effects.
