Dry skin around lips

I have had this light red rash around my lips for about 3 weeks. It's really embarrassing & people at school notice it. It's really only a light red line on the top & bottom of my lips. Around Christmas I started using Eos and they helped a little, but I haven't been able to get rid of the light shadow of red that's still always there. I don't think it's alergies because this is the first time this has ever happened & it doesn't itch, peal, or burn. It's just there & is extremely hard to get rid of. I'm not sure what this is or how to get rid of it. If someone could PLEASE help me, I'd really appreciate it a lot. None of the treatment solutions have been working, so I think a less common treatment might be the only answer. Thanks for ANY help you can offer.

Hi so I had a similar problem last winter and I tried everything. Finally I did some research and decided it might be due to a dietary deficiency. I stared eating foods rich in vitamins and minerals and I also started taking a multivitamin and the little red dry bit above my lip cleared up. Hope this helps!
