Oil from your skin will not bleach anything, BP will bleach clothing, bed sheets, etc.

I mean, after application and absorption of benzoyl peroxide - it will persist inside the skin. So if later skin will sweat - the mixture of sweat and absorbed benzoyl peroxide will bleach cloth. That's what I've read here on this forum. So my question is: can benzoyl peroxide mix with oil from the skin and thus bleach cloth, the same way as it mixes with sweat and then bleaches?

BP will bleach anything, no matter the mixture.

I'm sorry for misunderstanding and that I did not express myself clearly. I know that BP bleach everything. Finally, I can formulate exact question that bothers me:

Can oil (sebum) pick up benzoyl peroxide and make it liquid after it has dried and soaked into the skin, as well as it does sweat?

I don't have an answer but I'm as frustrated as you are with the fact that these two can't read.

I do believe that it can, yes. But I don't know the details as to how/when/why. In my experience sometimes things get bleached even hours later after I've applied the BP. Other times, I can go weeks doing the regimen and nothing gets bleached. I don't really get how it works.

I remember how bp used to ruin all of my towels, beddings and morning gowns. Even if I wash my face with a cleanser and then dry it with a towel, it would leave white spots. Once I applied it on my back before going to sleep, took a shower in the morning, put on clean clothes and went out for the day. In the evening I saw that my blouse got bleached on the back. So my answer to your question would be - probably yes, sweat can absorb bp and bleach clothes. But this is based on this particular experience.
