Why does hydrogen peroxide only bubble-up on abrasions and not your skin?

In brief: Chemical reaction
Peroxide bubbles up when it comes in contact with dead skin, bacteria, and other stuff that's present on skin abrasions.
Unabraded skin doesn't have enough foreign material on it to cause that reaction.
