Microsonic Facial Cleansing Brush

50 Years of Skin Technology Expertise,
Delivered in a 2-Minute Cleanse.

For over 50 years, Bio-Therapeutic has pioneered the use of advanced technology in the professional skincare industry. The bt-sonic brings that award-winning expertise to the home regimen — delivering professional-grade cleansing results with every use. Up to 24,000 microsonic vibrations per minute power the device, dislodging dirt, dead skin, and debris while dramatically enhancing the performance of your chosen cleanser or exfoliant — achieving up to 600% improvement in cleansing versus cleanser and hands alone. The anatomically optimized triangular cleansing head is uniquely designed to reach the hardest-to-access contours of the facial landscape, including around the nose, under the jawline, and near the eye area — areas where round brushes simply can't go. Azul silicone bristles are hygienic and silver ion-infused for antimicrobial and antibacterial properties, delivering superb cleansing and gentle exfoliation without the skin stress caused by traditional nylon brushes. The microsonic motor is strategically positioned at the base of the device's neck for maximum sonic activity transfer to the bristles, while intelligently managing power output to extend battery life. At just 2.8 oz with IPX6 water resistance, the bt-sonic is ideal for home, professional, and on-the-go use — including in the shower.

Gentle Exfoliate

Silver ion Azul silicone bristles remove dead skin cells and smooth texture without the irritation of traditional nylon brushes.

How to Use

Step-by-Step Protocol

Use daily in the morning and/or evening. Can be used in the shower. The full face can be cleansed in approximately 2 minutes.

1

Wet Your Face

Wet your face with water. The bt-sonic can be used in the shower or at the sink.

2

Apply Cleanser

Apply your favorite cleanser or exfoliant directly to the face or to the cleansing head of the bt-sonic.

3

Turn On & Cleanse

Turn on the bt-sonic using the silicone power button. Gently move the brush in circular motions over the face — including around the nose, under the jawline, and near the eye area. The full face takes approximately 2 minutes.

4

Rinse

Rinse your face and the brush with tepid water. Pat skin dry.

5

Clean & Store

Rinse the cleansing head thoroughly after each use. Dry the device with a towel — avoid leaving it in the shower overnight for maximum longevity. Store with the cleansing head cover in place.
