The Negative oxygen ions, known in the medical community as [air vitamins], is a natural factor that has an effective health care on the human body. 

02toDerm negative oxygen ion chamber is a beauty health equipment, which uses PSA pressure swing adsorption filter, absorbs natural air to compress it and discards nitrogen, and releases high concentration oxygen(90% pure oxygen) through a converter, while also releasing 3 million small particle size negative ions, thus called negative oxygen ions. 

Because of its extremely small diameter and high kinetic energy and activity, it enters the human body through the blood-brain barrier and circulatory system of the human body, improving the physiological activities of the body and exerting health care effects. O2toDerm oxygendome, used in beauty therapy, helps improve blood circulation, promote metabolism, reduce reactive oxygen species, repair damaged cells, improve immunity, solve problem skin, rejuvenate skin, and achieve anti-aging effect. 

It also improved its function by adding light therapy to oxygen therapy. Light treatment according to the characteristics of each wavelength is possible.
