Description Unlike blotting papers that are single-use, this roller is reusable and is made from natural volcanic stone that acts as an oil absorber. All you need to do is wash with a gentle cleanser, rinse, air dry, and place it back in for use! The roller can be used to prep your skin before makeup application, or throughout the day over your makeup. Suitable for most skin types. Replacement volcanic ball included. How To Use Remove the cap and gently roll the volcanic stone roller around your face, especially your T-zone (forehead and nose) area. Care Tips To clean, twist the locking ring around the stone clockwise to unlock. Gently push the volcanic stone down and remove it from its holder. Wash with warm water and a gentle cleanser. Rinse and air-dry overnight. Use the replacement volcanic ball alternately and lock back into place by twisting the locking ring anti-clockwise.
