The Glow Signature uses two ultrasound frequencies — 3 MHz and 10 MHz — to target different depths of the skin. 10 MHz works on the skin's surface layer, while 3 MHz reaches deeper layers. By combining both, the device can address multiple skin concerns, from surface radiance to deeper hydration and firmness, in a single session.

Each full session runs for 12 minutes, guided by the device's built-in voice guidance. We recommend using it once daily, adjusting frequency based on your skin's needs and tolerance.

THOME's ultrasound technology devices are designed to pair with THOME Boost Ampoules for the best glide, compatibility, and results. You can use other skincare products, but we recommend a THOME Boost Ampoule for the intended experience.

We recommend a 5V, 1A adapter with the included USB-C cable — a fast charger or higher-output adapter may shorten the device's lifespan. The LED indicator lights up white while charging, and stays lit for 5 seconds once fully charged before turning off.

Wipe the head with a soft, dry cloth after each use. Avoid alcohol-soaked pads, harsh chemicals, or scrubbing the surface, as these can damage it.

These devices are not recommended for anyone who is pregnant or breastfeeding, has a pacemaker or other implantable medical device, has a serious heart condition, is prone to seizures, or has sensitive/highly reactive skin. It should not be used by children aged 12 or under. If you have any of these conditions or other health concerns, please consult a doctor before use.
