I’m 22 and a smoker but never had this problem as long as I’ve been smoking. About a little over a month ago I noticed my lips becoming more dry than usual soon later followed black regions and days after that peeling lips. Now today my lips aren’t as dry anymore but now they still have black regions accompanied by redness. Also there was no irritation, no itching, no burning, i didn’t even notice until seeing it in the mirror and its on my lip not around. Any possible diagnosis?
