I get outbreaks of angular cheilitis occasionally (typically due to stress). It's not very severe - there's no scarring and typically no bleeding. I use coconut oil until it goes away. I read that fillers like juvederm can be used similarly to how marionette lines would be treated to help treat the angular cheilitis. I'm in my late 20's and have full lips as is and marionette lines are not of any concern to me. I wanted to see if anyone has done this treatment or has more information. Thank you!
