I think I may be allergic to things on my lips.
Everytime I apply lipstick, gloss, lip balm - anything (with the exception of Zovirax or the original blistex) I end up with cold sore like blisters the next day. Vaseline lip balm is specifically horrendous - I ended up with about 7 on my lips which was very attractive 
I've replaced my lipsticks (in case I was cross contaminating myself) so it's not that.
Anyone else have this issue? If so, what can I use on my lips to look glam?
