Derma rollers are cylindrical rolling devices with several rows of tiny needles. When the tool is rolled over the skin, the needles puncture the surface of the skin, which breaks down scar tissue and helps build up collagen and stimulate growth of healthy new cells. The roller can be used on the neck, stomach, buttocks, arms and thighs to improve the appearance of flaws in the surface of the skin, including acne scars and wrinkles. Derma roller treatments are available at dermatology clinics, spas and salons, and rollers are available for use at home.
Wash your hands and the area of skin to be treated with body soap or liquid hand soap, then rinse thoroughly and dry your skin with a soft towel. Wipe the area to be treated with rubbing alcohol.
Pull the skin taut with your nonworking hand, then roll the derma roller gently across the area two or three times. Roll one direction, then turn the roller and roll the skin in the opposite direction. If you notice tiny blood spots or if you feel pain, you are pushing too hard.
Smooth moisturizer over the treated area. If you accidentally penetrated your skin, apply an antibacterial cream or gel.
Rinse the derma roller under hot water, then let it air dry and store it in a clean, dry place. Disinfect the roller after every four to five uses by standing it in a glass of rubbing alcohol for one minute. You can use a derma roller up to five times per week, but never more than once in a day.
