The Exfoliating Brush is made of hygienic, quick-drying bristles that help lift away debris trapped deep within your pores. Effectively removes traces of makeup, dirt and oil left behind from manual cleansing. Use the Exfoliating Brush Head for deep cleansing 1-2 times per week. To avoid frayed bristles and to ensure effective cleansing, dermatologists recommend replacing your brush heads every 2-3 months. Designed specifically for the Vanity Planet Ultimate Skin Spa Facial Cleansing Brush and the Vanity Planet Glowspin Facial Brush
