An oxygen facial delivers a mixture of hyperbaric oxygen, or pure oxygen at a high pressure, and anti-aging serum through an airbrush to the face and body. It's almost as though someone is using a tiny power washer to pump oxygen and moisturizer into the skin. People who use oxygen facials say the process helps makeup application because it gives the skin a smooth and moisturized surface [source: Singer]. Makeup also can be applied right after the oxygen facial, as opposed to traditional facials, which often require a 12-hour waiting period before you can apply any makeup.

Many doctors say that the oxygen facial's effectiveness has not yet been proven because of a lack of clinical study. But those who offer the treatments say the facials can force oxygen and moisturizers into the skin for a temporary improvement. And the celebrities who swear by the treatment say it makes their faces flawless, even in a high-definition world.
