What a good question. This is one of those questions where I'm like "how have I not heard this before?"

I found a few MDs answering the question here, but please note that I am simply sending you to a link that I googled. I do not know for sure and have not done the research myself yet: https://www.realself.com/question/tel-aviv-il-led-light-therapy-apply-benzoyl-peroxide-gel-25-night

Thanks!
