99% Isopropyl Alcohol
Directions
Alcohols do not not dissolve proteins (as found in blood and skin), so you’ll need to use a detergent. Wash the Derma Roller in warm water with a couple of drops of dishwashing liquid, taking care not to touch the needles. You can move it vigorously in the water. Do not use a dishwasher or boiling water because it will damage the needles. This washing merely cleans the roller, it does not disinfect it.
Rinse the Derma Roller with clean (tap) water and dry with a paper towel. Spray the Derma Roller cleaner onto the micro needles and allow to air dry. Once dry, put the Derma Roller back in its original storage case.
