Skin, being the largest organ, critically assists the respiratory system by breathing in oxygen and expelling carbon dioxide. We do not get enough O2 from our lungs alone. For this reason, heavy face creams can often obstruct this vital function and lead to skin degeneration and premature aging. It takes 22 parts of oxygen per one part nutrient to have a perfect metabolic process. The Oxygen Replenish delivers oxygen directly to skin cells to assist in skin cell metabolism while riding skin of harmful bacteria and pathogens that impair cell functions.
