How should I clean and store the roller to maintain hygiene?

Because the roller’s metal tips are in direct contact with the skin, keeping them clean is essential to avoid transferring oils or bacteria back onto the face. After each use, rinse the entire applicator under lukewarm running water to remove surface residue; a mild, fragrance‑free soap can be used if visible dirt is present, but avoid abrasive scrubs that could damage the rubber base. Pat the roller dry with a clean, lint‑free towel, making sure that moisture does not remain in the needle array or on the rubber surface.

Once dry, store the roller in a closed, dry container or a dedicated pouch that protects the needle tips from accidental bending or dust accumulation. It is best to keep it away from humid environments such as bathrooms, as prolonged moisture can encourage mold growth on the rubber and may lead to corrosion of the metal components over time. Do not share the device with others, and if you notice any discoloration, persistent odor or damage to the rubber, discontinue use and replace the roller.
