Replacement brush heads are made from a non-porous, super soft filament which is resistant to attracting bacteria. The Deep Pore head is precision-designed to cleanse deep into your pores to remove impurities and reduce oil and blemishes. It is ideal for oily skin, large pores, or difficult to reach areas of the face. The Sensitive head is precision-designed for effective use on the face, décolletage, and body for sensitive or combination skin types. The Radiance head gently cleanses away dullness to reveal radiant skin. Our replacement brush heads are manufactured in a facility approved by the FDA. With daily use, the brush leaves skin feeling and looking smoother and increases topical product absorption for improved cleansing. For best results, replace your brush head every 3 months. The brush is safe and gentle for daily use as part of a facial care regimen. It massages skin and increases circulation, thus improving product absorption. To remove the brush head, grip it firmly, then push and twist it counter-clockwise. To attach the brush head, push down and twist the head clockwise until it snaps into place. Use the brush head cap to easily remove and attach the brush head with a simple twist. Compatible with Mia, Mia 2, Mia 3, Aria, Pro, and Plus Cleansing Systems. Condition: New.
