To prevent shower water from becoming an irritant to your skin and hair, ReFa applied breakthrough Japanese fine bubble technology to the design of this revolutionary showerhead. Far smaller than the bubbles we’re used to seeing when we bathe, ultrafine bubbles and microbubbles have a unique cleansing capability that transforms bathing into a luxurious beauty routine.

01. Hydrophobic dirt particles attach to the hydrophobic surfaces of the bubbles. 02. By absorbing these dirt particles while floating to the skin’s surface, the bubbles gently remove them from the skin.

ReFa's technology enables this device to generate two kinds of bubbles for even more beautiful skin. Showering with ultrafine bubbles and microbubbles removes dirt and grime from the pores of your skin and scalp gently, comfortably, and thoroughly. Fill your bathtub with ultrafine bubbles and microbubbles, and envelop your body in the warmth and comfort of a silky-soft fine bubble bath. Enjoy the comfort and relaxation of an at-home spa experience, brought to you by the science of bubbles.

With its two types of bubbles, the ReFa FINE BUBBLE ONE washes away dirt particles with water that feels as smooth as silk—and provides the skin with vital hydration.

The water content of the skin’s surface immediately after use was about 22% higher than it was before use.

Subjects: 17 men and women aged from 26 to 60.
Test method: Washed the subjects' hands with soap and let them acclimate in a 20°C ± 1°C room for 20 minutes. Showered the backs of the subjects' hands (temperature: 36.5°C ± 0.5°C; flow rate: 5.00 ± 1 mL/min.) for 40 seconds with the bubble feature (set to level 2) and without it (set to OFF), then measured the water content of the skin's surface.
