text: help! i have always had really dry lips. this happens even after i use chapstick. i think i am allergic to? chapstick. i have had other pollen allergies in the past. or could i be allergic to toothpaste? i kissed my boyfriend and he said his lips got dry too because of me. he used my chapstick once and also got this problem. any dermatologist out there, please help? i have had this problem for a while. first stop kissing your boyfriend to see if it stops.  then go to a doctor.
