The Deep Pore Cleansing Brush Head uses an advanced dual-action motion to effectively cleanse oily skin, large pores, and those hard-to-reach areas on your face. It can be introduced into your cleansing regimen, when your skin seems particularly oily or in need of a deep-pore cleansing. It is safe and gentle for use twice a day if you're prone to large pores or consistently oily skin. It is recommended to replace brush heads every 3 months!
