Could the person asking about Angular Cheilitis check this out?
There were some answers to the question about treatment for Angular Cheilitis, but none contained the perfect, simple remedy that I found, thanks to my dentist. He suggested I try taking a small amount of vitamin B1 (Thiamine) daily. Within just a few days, it disappeared and has stayed away as long as I’m faithful taking the supplement. It only takes 2 days off the B1 for it to begin to return. Hope this helps a little.
