Chemical-free micro-nano bubble skin care system Micro-nano bubble technology was developed in early 1980s and is now widely used in water treatment, industry cleaning/degreasing, etc. In recent two years, micro-nano bubble bath has been introduced into spa centers for its incomparable chemical-free skin care functions. CoralSeaSpas.Com is proud to be the first one to introduce micro-nano bubble system into bathtubs for the purpose of home wellness. From now on, consumers are able to enjoy superb chemical-free skin care at home with everyday's bath! Here comes the dream wellness/spa center at home era! Benefits of micro-nano bubble bath Micro-nano bubble bath proves to have the following effects as a chemical-free skin care method: - Billions of micro-nano bubbles in the water come deeply into pores of skin and make perfect cleaning of pores. Old keratins are removed naturally.
- Large amount of micro-nano bubbles in the water increases a lot the amount of Oxygen in the skin and enhances blood circulation. It activates cells and speeds the process of metabolizing.
- Negatively charged micro-nano bubbles attracts bacteria and when they break, created heat and hydroxyl radicals destroy bacteria. After bathing in micro-nano bubble bath for a few times, obvious skin detoxification and dermatoses improvement effects will be achieved.
- Supersonic sound is generated when micro-nano bubbles pop around the body. This supersonic sound penetrates the depth of the body and warms up from the inside of the body. Great soothing effect is thus achieved.
- Negative Oxygen Ions released on the surface of water bring extremely fresh air to the bather.
What’s micro-nano bubble Let's have a look what micro-nano bubble is and what features they have.
- Micro-nano bubble is under 30 micrometres in diameter. They are smaller than skin pores thus have great skin-cleaning function.
 - They have high inner pressure. The surface tension of water make micro bubbles smaller and smaller resulting very high inner pressure. With mechanical shock and natural pressure increase, they break and create extremely high temperature spots and hydroxyl radicals.
 - They have slow rise rate. The micro-nano bubbles float in water as if cigarette smoke floats in air. While normal air bubbles go rapidly over water and burst. Large amounts of micro-nano bubbles turn water into milky.
 - The surface of micro-nano bubbles is negatively charged. Negatively charged bubbles attract bacteria and when they break, created heat and hydroxyl radicals destroy bacteria.
