eli5 why skin turns white after using hydrogen peroxide?

193 views

I was mixing hydrogen peroxide with water for my plants, and some of the peroxide dripped on to my hand while I was pouring it into the squirt bottle. I didn’t think anything of it until the skin that the droplet was on turned bright white. I’ve tried to Google this, but I keep getting different answers (and I don’t understand them). Why does this occur?

“When the catalase reacts with hydrogen peroxide, oxygen bubbles are formed, diluting the blood and preventing smooth blood flow. This chemical reaction whitens the skin as blood is absent.”

It’s a capillary embolism. The peroxide creates little oxygen bubbles that stop blood flow in the capillaries in skin temporarily. It makes it look bleached.
