As with all microneedling tools for home use, we recommend sterilizing the bottle, cap, and .25 guage roller before, and after use with appropriate disinfecting solution or isopropyl achohol of 70% or above, and not less. Sterilizing the roller should be done promptly after the procedure. Dip the head into a cup of isopropyl alcohol (IPA) and let it soak for fifteen minutes minimum. Any homebrand solution is sufficient, again-as long as it is at least 70% alcohol. Return the cover soon after, as it prevents the pins/ needles from getting damaged.
With extended use the pins will eventually become dull, and possibly bend as is normal will any such microneedle tool. It is recommended to replace a dull or damaged HydraRoller tool.

Great value! I add my PLLA Mist and some other potions. Very easy to use and good quality. I will continue to use and purchase more as I go.
