Achieve a thorough yet exceptionally gentle clean with the Clarisonic Sensitive Replacement Brush Head. Specifically precision-engineered for sensitive, combination, and dry skin types, this facial cleansing brush head features plush, ultra-soft bristles that comfortably glide over the skin without tugging or causing irritation. Designed to oscillate bi-directionally at sonic frequencies, it effectively flushes away deep-seated dirt, makeup, sweat, and oil from your pores while completely respecting the skin's natural moisture barrier. Perfect for daily use, it helps prep your skin for better absorption of serums, oils, and moisturizers. Ultra-Gentle Cleansing: Features a velvet-like bristle gradation and dome-shaped profile tailored to deliver concentrated pore-flushing action on delicate or compromised skin. Hygienic & Anti-Bacterial: Crafted from a high-quality, nonporous elastomeric material that resists bacterial attachment, keeping your brush head cleaner and fresher for longer. Universal Compatibility: Precision-engineered to perfectly snap onto all Clarisonic Sonic Facial Cleansing Systems (including Mia 1, Mia 2, Mia Smart, PLUS, and PRO). Dermatologist Recommended: Safe and effective for daily use, promoting a smoother, brighter, and more radiant complexion without harsh abrasion. To Remove: Grip the old brush head firmly, push down and twist it counter-clockwise (like a medicine cap), then pull it away from the handle. To Attach: Align the three internal notches with the pins on the handle, push down, and twist the new head clockwise until you hear a tight snap. Maintenance: After each use, rinse the bristles thoroughly with warm water and a little antibacterial soap. Skin care experts recommend replacing your Clarisonic brush head every 90 days to maintain optimal hygiene and performance.
