Ultrafine Bubbles & Microbubbles:

Two kinds of bubbles for even more beautiful skin

To keep the water in your bath or shower from irritating your skin, ReFa has incorporated Japanese Fine Bubble technology into the design of the ReFa FINE BUBBLE S. This technology enables our revolutionary showerhead to create two kinds of bubbles: ultrafine bubbles and microbubbles. Substantially smaller than typical bubbles, each type possesses a unique cleansing mechanism that unclogs pores to help bring out the visible beauty of your skin.



Double the cleansing capability

Ultrafine bubbles gently flush out your pores to remove impurities from deep inside of them, while
microbubbles unclog pores by latching onto impurities and floating away.

1. Ultrafine bubbles latch onto impurities in the pores and float away.

2. The process of attaching and floating away is repeated until even the tiniest impurities are removed.

1. Microbubbles latch onto impurities that have built up in the pores.

2. The bubbles remove the built-up impurities.

Scalp Cleansing

Use the Jet mode of ReFa FINE BUBBLE S to give your scalp an intense clean.

Cleansing Mechanism: Hydrophobic Interaction

1. Hydrophobic dirt particles attach to the hydrophobic surfaces of the bubbles.

2. As dirt floats to the surface, the bubbles help absorb particles to remove them effectively.


Hydrate As You Cleanse

Ultrafine bubbles and microbubbles hydrate the skin as they gently remove impurities.

*Subjects: 7 subjects, male and female, ranging in age from 22 to 50. Test method: Washed the subjects’ hands with soap and let them acclimate in a 17.7° C +/- 1° C room for 20 minutes. Exposed the backs of the subjects’ hands to the ReFa FINE BUBBLE S on Mist mode (temperature 36.0 +/- 2° C, flow rate 4.6 +/- 0.4L/min) for 40 seconds, then measured the water content of the stratum corneum.


A Choice Of Four Spray Patterns To
Meet Your Skin's Needs

With four separate spray patterns to choose from, the ReFa FINE BUBBLE S can be customized to
meet a variety of skin needs: removing impurities from a particular area, warming your whole body,
or saturating your skin with hydration.
