What happens to someone's skin when they put hydrogen peroxide on their face?

Hydrogen peroxide is: a powerful oxidizer. It bubbles on skin when H2O2 separates into oxygen O and water H2O. If left on the skin for a period of time, the oxygen is absorbed into the dermis and creates small oxygen bubbles in the tiny capillaries at the skin surface and turns the skin white. Short periods of exposure have slight antibacterial properties. But long exposure will dry your skin. Rinse with plain water.
