Hi, Im just curious on the effects of hydrogen peroxide on human skin.
I know that its good for cuts and everything, but why does my skin go
white if i put some peroxide on it? is the stinging sensation a sign
that its working?
It sounds like you're using food grade 35% hydrogen peroxide. You
should not use this full strength internally or externally. The 3%
solution is what you want to use or dillute what you have down.
Good luck and have a good day.

Actually this is 3% hydrogen peroxide I bought At the drug store. It
has been sitting my a bowl for about a week now. The room it was
sitting is quite dark and fairly dry.
Im guessing here, but what i tihnk is the water (H2O) molecules
evaporated, and the heavier (H2O2) peroxide molecules stayed in the
bowl. Is this at all possible?
Mind you, I put it on a clean piece of skin which I washed with water
and soap. I rinsed thoroughly to make sure the soap was washed off. So
im not sure what its reacting to, clean skin?
I would like to find out why its doing this, is this natural for
peroxide to do? even 35% ones?

The whitening is due to the formation of gas bubbles in the epidermal
layer of the skin. Highly concentrated hydrogen peroxide can cause
blistering if left on skin surfaces for any length of time.

interesting. So i guess the extra oxygen molecule is breaking off
because its reacting to something. would dead skin be the culprit in
this case??
The blistering goes away after a certain amount of time, right?

Bacteria, I suppose.

I guess it depends on the length and concentration of exposure.

Im not exactly sure that bacteria has anything to do with it. I wash my
hands with soap 3 times before i let my hand sit in the peroxide. Would
dead skin be a culprit? Also, if its reacting to the dead skins cells,
is it possible it could take out any bacteria with the dead cells?

I doubt bacteria can be completely removed, but I don't know the
answers to your questions. Try a web search.

Why are you doing this? Although H2O2 is a pretty good disinfectant, it
kills live cells, too. What else it may be doing to your skin if you are
doing it often, I don't really know, but I doubt the risk outweighs any
benefits. We sometimes use H2O2, (3.5% further diluted with sterile 5%
saline) to irrigate particularly dirty wounds before suture repair, but we
don't recommend repeated use.
