Genuine Clarisonic-branded Sonic Foundation Brush Head for their now discontinued Clarisonic Facial Skin Device. It is designed to facilitate smooth and even application of liquid facial foundation as well as liquid (and lighter textures of cream) contour, blush and highlighter makeup. It it intended to produce an airbrushed and more flawless makeup look in less time and by using less product than with other application methods. It is compatible for use only with genuine Clarisonic branded Facial Devices (such as Mia 1, Mia 2, Mia Fit, Smart Profile... possibly other models). The brush head is brand new (never used!) and comes in its original box. There are no 'tags' as no tags or stickers were attached to the box when this item was originally purchased. I dearly miss my beloved Clarisonic Smart Profile Facial Cleansing Brush that finally stopped working after several years. I was left with 2 brand new brush heads, this being one of them. My new Sonic Exfoliator brush-head was previously listed and sold here separately.)
