Compatible with every model, our facial brush heads vary to accommodate a range of skin types. Suitable for all skin types, particularly sensitive skin. To keep your brush head clean, simply rinse the brush head with soap and warm water. We recommend replacing your Clarisonic brush head every 3-4 months. To replace your brush heads remove it, grip firmly, then push and twist it counter clockwise and pull the head away from the handle. To attach the brush head, push down and twist the head clockwise until it snaps into place. Be sure you hear a tight snap. Size: Colour:
