① First 1 micrometer bubble generating beauty device (FINE BUBBLE PURE)
- Ultra fine air bubbles What is ultra fine bubble?
Microbubbles that are more than 1000 times smaller than regular bubbles, smaller than pores that are about 70 to 80 micrometers in hair and 20 to 50 micrometers in size.
- Microbubbles remove skin surface waste blocking pores, penetrate into pores with ultra-fine bubbles to remove waste, and double-cleaning effects of microbubbles and ultra-fine bubbles.
- Suppression of damage to the skin barrier, improvement of atopic dermatitis, suppression of itchiness and skin roughness.
- Immediately after use, the moisture content of the stratum corneum increased by about 51%, and the moisture of the skin with fine bubbles continued.
- Two-stage cavitation method based on the principle of pressure dissolution: As soon as the pressure of the water is increased, the dissolved air is instantly turned into a 'fine bubble' when the pressure is released and released.

② Product Description
Transform your daily shower into a professional-grade skincare ritual with the ReFa Fine Bubble Pure Shower Head bundled with the ReFa Pure Cartridge — a complete set engineered in Japan by MTG Co., Ltd. for those who care deeply about the quality of water touching their skin every day.
Powered by Japanese Fine Bubble Technology certified by the Fine Bubble Industries Association (FBIA), this showerhead generates two types of bubbles simultaneously — Ultra Fine Bubbles (avg. 0.15 µm diameter) and Microbubbles (avg. 31 µm diameter). Using a patented Double Cavitation mechanism, ultrafine bubbles penetrate deep into pores to flush out impurities, while microbubbles latch onto surface-level dirt and oils, lifting them away without stripping the skin's natural moisture barrier. Clinical testing on 8 subjects confirmed that water from the ReFa Fine Bubble Pure permeates the skin's keratin layer deeply and evenly, leaving skin noticeably more hydrated after just 40 seconds of exposure.
The included ReFa Pure Cartridge adds a vital layer of water purification: its unique dual-layer filtration system — calcium sulfite (upper layer) and composite fiber filter (lower layer) — continuously reduces residual chlorine and removes dirt particles from water, delivering pure, clean water with every use. This set is ideal for sensitive skin types and anyone seeking chlorine-free, bubble-enriched water as part of their daily skincare routine.
Choose from 4 spray modes (Mist, Pure Straight, Straight, Jet) to match your skin's needs, and enjoy water savings of up to 53% in Mist mode. You can even submerge the head in a filled bathtub for a spa-quality silky bubble bath at home.
