The Clinique for Men Sonic System Deep Cleansing Brush Head is a purifying brush head with charcoal-grey bristles that cleans more effectively than hand washing alone. It gently removes dirt and oil while its two bristle types go easy on your cheeks and firm on your forehead, chin and nose while prepping for a comfortable shave. Gentle sonic action helps your skin look energized and vital. Clinique recommends changing your brush heads every three months. How to use: Apply face wash to moistened skin or your brush head. Massage in a circular motion for 15 seconds on cheeks using the lighter grey bristles. No need to apply pressure. Massage in up-and-down motion for 15 seconds combined on forehead, nose and chin using the darker grey bristles. Style Name: Clinique For Men Sonic System Deep Cleansing Brush Head.
