So why does oxygen work to make our skin smoother and softer? The theory behind oxygenated beauty is that we all need oxygen for survival. Oxygen is what revives and replenishes the cells in our body. However, due to the pollutants in our environment today, our oxygen content has been greatly reduced. It is also true that as we age, oxygen does not reach our skin cells as efficiently, which is what leads to the aging process. The result can be thinner skin and the appearance of wrinkles and age spots. An oxygen facial will replenish the amount of oxygen that the skin receives, leaving it hydrated, plumper and younger looking.
