Wow! That sucks.
Could it be possible that you picked up some kind of infection from your friends makeup? Maybe it is something tenacious, that just won't go away, and is now being aggrivated by products. Whatever the cause...I feel for you.
I have developed an allergy of sorts to makeup around that time of the month. If ANY makeup goes near my mouth, it gets super itchy, and then I have red marks around my lips. The only makeup I can wear when this happens is mineral makeup. During this time, the only products I can use are Cetaphil (cleanser), essential oils to moisten my skin, and mineral makeup.
I hope you can get a handle on this problem of yours. It sounds so uncomfortable for you!
