Try turmeric 1 teaspoon and a pinch of black pepper in glass of hot water can add ginger, drink it as a tea, this will kill internal bacterial and fungal organisms especially staph, can drink
2wice a day. Take probiotic acidophilus tablets as well. Can take 1 acidophilus tablet by swallowing it, the other break open and can put into small orange drink or any cold drink and drink it swish mouth with it don't take anything hot after taking the acidophilus tablets cos will kill beneficial bacteria. By the way read that peristaltic waves of stomach becomes greatly reduced at night allowing the bacterial/fungal to multiply and overgrow in the gut, I don't know if its related to lips being worse with each increasing day until they exfoliate, since the critters multiply best at night. Am presently taking the turmeric drink at night and the acidophilus tablets for general well being, if its the last thing in your stomach at night you should wake up hopefully with a healthier flora of gut, mouth and lips. Good luck.
