Hello everyone!!
I was thinking to get some BP 2.5% to help clearing my skin, but I saw a few post where people said their PIH marks started to get worse. I have a lot of PIH marks on my cheeks, but I don't get any cysts or anything like that, I have like a lot of small pimples concentrated on my forehead, cheeks (where the PIH is), on my eyebrows (yeah -.-") and chin area. I really want those pimples to go away because my skin hasn't been smooth for 5 years now, but I'm scared that the BP makes my skin worse. I also have some bigger pimples on the upper side of my cheeks. I may say that my PIH marks are really red and dark... 
What do you guys think?
Thank you for answering!
I don't think BP makes red marks darker. That's probably just a psychology thing. What I do know is that once BP clears your acne, red marks might be left behind. The marks themselves aren't caused by BP. They're just due to your body's inflammation response.
I really think you should use it. I've been using it for a few years, and I was recently reminded how awesome it was. I applied makeup to both my face & neck, but I broke out only on my neck (where I don't apply BP).

I've been using the benzoyl peroxide cream for 3 weeks now and it's definitely improved my acne. I've noticed it leaves red marks on my skin but you can remove those by regularly applying a honey and milk mask which soothes the skin. You can track the progress using the SkinStory app, that's what I've done: here's the link: {LINK REMOVED}
