I got what I thought was a pimple on my lip yesterday, it's on the edge of my top lip, raised, red, and pus-y. Then today I started getting two of what look like blisters, they're just raised and red, on the surface of my lips. I recently got off Accutane, I have celiac disease (my symptoms include dermatitis herpetiformus amen I've been breaking out lately), and I recently started using this gold flake serum that I ordered form some sketchy site from China on my lips, so there are a lot of things that could have caused this and I'd just like to figure it out. I haven't kissed anyone/had sex in almost a year and I don't really share food, makeup brushes, etc. with anyone. I'm 18 years old and I've also had a cold recently (scratchy voice, congestion). So basically what I'm trying to figure out is what caused the lesions, what they are, and if/how I can treat it. So far I've put alcohol on my lips and an acne cream on the one that looks most like a pimple, that was a few hours ago and nothing's changed. I don't know how to/if I can add pictures. Thanks for the help!
