I started smoking about 2 years ago and never had any lip related issues. As of last month (April 2016) I started getting this lower black/blue ish lower lip. You can only see it when I talk because it mainly on the inner side of my lower lip. My upper lip is starting to get it as well. My lips are pretty dry too. I drink alot of water, use extra virgin olive oil, vaselina and chapstick nothing helps. I think its getting worse. PLEASE help! I dont want to have dirty blackish lips.
