I ordered this a few weeks ago. The first week I used it every night, and nothing changed. No worse, no better. I definitely didn't have purging pores
I've used it several times since then but don't really see the point now, I have stuff I like better like Paula's BHA. I'm also not taking B5 internally, so that may be why. I'll probably send it back. It's not very expensive though, so it's worth a try especially if you're taking B5 supplements.
