I get impetigo on my upper and lower lips on and off for a few years now. As soon as I feel it coming on I take Keflex oral antibiotics and start using my mupirocin cream 2%. It’s usually gone in 5 days to a week. So the big question is why am I getting this!? Well finally after seeing a few different urgent care doctors and a few dermatologists only one suggested I may have staph bacteria up inside my nose and I should try sanitizing my nostrils and putting the mupirocin cream up there daily. So I purchased a small bottle of Nozin nasal sanitizer and have been using that daily in hopes to kill any staph that may be harboring in my nose causing the impetigo on my lips every few months. Worth a try for all of you suffering from this as well. I just started it so can’t tell you if it works or not but I thought I’d share. It makes sense if you think about it, we blow our nose but it’s never “cleaned” or sanitized so I’m hoping this will keep me from getting nasty impetigo on my lips again fingers crossed
