I have used chapstick my whole life, different brands. Within the last year or so if I use chapstick, the skin around my mouth gets very dry and red. I had recently purchased a all natural chapstick, low and behold around a week later I have the redness around my mouth. Before when I have had this I tried eucerin, vaseline, aquafor with no help, i eventually had to do a medrol dose pak. What is causing me to break out and what can I use on my lips to help dryness?
