Up until recently I had normal teenage skin with no major acne or dryness problems but a few days ago the skin around my mouth started to become dry and flaky. It started with the area in the creases of my nose a week ago and then two days ago the skin around my lips started to become dry and red. The lips themselves aren't chapped just the skin above and on the sides. I have been drinking a lot of water and keeping it well moisturizer. I'm a vegetarian so I wasn't sure if it was from a lack of nutrition. I have read online that it might be caused by making out but I wanted to make sure it wasn't a serious problem.
