O2 to Derm, also known as Oxygen Glass Facial or Oxygen Dome Therapy, is a hyperbaric anion oxygen system. The revolutionary system turns natural air into pure oxygen of up to 92% and delivers it through the dome-shaped mask in a hyperbaric-like chamber. It generates the amount of anion ( negative anion) by 3 million more than natural production. Anions are vitamins from the air, similar to what you get in a deep forest. They induce and stabilize free radicals which in turn regenerate new cells, reduce bacteria, rebalance PH levels, improve signs of aging, correct and heal damaged cells.
