I put my benzoyl peroxide in the fridge and have been using it chilled lately. I like it a lot. We know that ice/cold reduces inflammation, so it certainly can’t hurt. I am uncertain, but I have a feeling it doesn’t help too much either. My skin warms up the BP in only a matter of seconds really. Regardless, I think I’ll continue using the BP this way. It’s been hot around here lately and a nice cool application of BP feels good. I almost look forward to it. I’d love to get more comments on this method if you’ve tried it.
