Time to quit

While some doctors disagree on whether smoking causes acne or not, there is evidence to suggest it does. Researchers at the San Gallicano Dermatological Institute in Rome identified non-inflammatory acne (NIA) to be common among frequent smokers. They also found that smokers who had experienced acne in their teen years were four times more likely to have acne as an adult than non-smokers who also had acne in their teens. So if you're breaking out and still lighting up, reconsider your deadly habit.
