Daily cleansing: the brush is ideal for deep cleansing of the face, freeing the skin of all impurities, dead cells, makeup residue or smog, making the skin cleaner and smoother. Sonic Technology: Low-frequency sonic pulsations help remove dirt, grease and makeup residue. Low frequency pulsations increase blood circulation to areas prone to wrinkle formation, enhancing collagen and elastin production to restore skin tone. High Quality Materials: Made with silicone bristles for gentle cleansing on the skin without any damage or abrasion like traditional nylon brushes. Also, the steel part is ideal for massaging around the eyes to reduce dark circles and eliminate wrinkles. Adjustable: The speed is adjustable depending on the area you are treating so you can choose the best treatment for your skin. Waterproof and rechargeable: the brush body is IPX7 waterproof, can be used comfortably in the shower, bathtub or sink. Easy to take with you everywhere.
