Why are my lips going all dry and red? they really hurt too and i dont know why?

I do not have a definite answer but if lick your lip that may cause dryness and redness so do stop and use lip balm to help healing. There are vitamin deficiency like vitamin A or B that could cause lip lesions so make sure to eat a balanced diet and probably add multivatimins. You may also want to check if you are reacting to lipstick if you use one. I hope you get better soon.
