3-level alternating ultrasound, made easy.
TEENZ switches between 1, 3 and 10 MHz, 32,700 times per session. That is 1 million, 3 million and 10 million gentle vibrations per second.
Micro-Bubble Massage
Lower frequencies create tiny micro-bubbles that gently massage the skin's outer layer and help your skincare absorb. This is why 1 MHz matters.

Loved by Quadthera Korea customers
Reviews translated from Korean.
"I had my eye on the Titan but hesitated because of the price, and then TEENZ came out, so I bought it right away. ... It's easy to carry and light, so I reach for it easily. For the price, I'm completely satisfied."
"What I like most is that there's no gap between the head and the body. ... TEENZ has no gap, so it's very easy to wipe clean. For a device you use daily, light and easy is best."
"I already own the Quadthera Titan and use it a lot. Among ultrasound devices, Quadthera is the brand I trust most. But the Titan was a bit much to carry when I travel. ... It's so cute and light, and the color is pretty!"
