Smoothing, firm. Polishes rough skin on knees, elbows and arms. The Clarisonic Body Brush Head smoothes skin and reduces dry patches. Only for use with the Clarisonic PLUS and PRO models. When the Body Brush Head is attached, the Clarisonic PLUS and PRO handles switch to Body Mode and the T-Timer® is automatically set to three minutes. Pressing the speed button while in Body Mode toggles between constant and pulse settings. The pulse setting is great for the head/neck area and provides a different sensation than the constant setting. Clarisonic Brush Heads are expertly engineered for a specific skin type or skin concern, and are optimally designed to work at the precise frequency of our devices. Made with super-soft, quick-drying DuPont® Tynex® Supersoft Filament, each bristle is uniquely rounded on the end or specifically texturized to provide a gentle and comfortable cleanse. We cannot guarantee the efficacy, durability, or long term impact on the device itself, of brush heads not engineered by Clarisonic.
