The immediate effect of concentrated oxygen on the skin appears to be beneficial. In the Utube demo there seems to be a nebulizing effect as well, ie moisture/water making it all look good.
However a little later the benzoyl peroxide concentration generated is part of the bad news. I hear that skin does not have an aerobic metabolism and therefore any benefits that increased oxygen levels have on the skin are short-term and the long-term effects are not good.
I would stay away from all this superficial, gimmicky stuff that probably has more bad effects on the healing properties after a few days.
