Face: Keep your face clean, you’ve just made a bunch of holes on your face. A face product with antimicrobial properties will help to combat that and keep your skin free healthy and safe. The safest route would be to not use any product for several hours after dermarolling, though we have not seen any adverse effects of using lotion immediately after dermarolling. It can be beneficial to apply a good (non-DHT blocking) beard oil or lotion.
Dermaroller: Rinse under warm water for a few seconds to remove any skin or other superficial debris like blood. Optional to disinfect dermaroller after using (use same method as described before dermarolling)
