Easy & Painless → Whether you are well experienced or completely new to microneedling, our 0.25mm or 0.3mm micro roller size is one of the safest and most effective derma rollers available. Safety First! Sterilize the roller in an alcohol solution before and after each use. Wash your skin and pat dry. Roll the Microneedle Derma Roller over the desired area, back and forth, 4-5 times. Be careful to apply pressure without puncturing the skin. Switch direction and roll back and forth for another 4-5 times. After rolling, apply a moisturizer or repairing serum. Don't forget to sanitize and store in the provided plastic case!
