Nutritional yeast cured my angular cheilitis within a few days. It's high in B vitamins.
Angular Cheilitis is very painful and I get it every winter. It can be very difficult to treat but here is what I do.
Listerine - Yellow one
Wetnaps - individual regular scent
Lotrimin for Athletes Foot
Clean both sides of mouth with the Wetnap. Dab dry with a clean paper towel.
Dab on Listerine or Hydrogen Peroxide and wait for one minute.
Dab on Lotrimin with two Qtips both sides and wait for one minute.
Dab on Carmex or Aquaphor on the lips with a Qtip. Do not eat or drink anything for at least ten minutes.
AC is a fungus and extremely hard to treat but one must be diligent and do this at least three or four times a day.
After doing the above for five days it has finally cleared up and I can now open my mouth. I do want to add THROW OUT all lipsticks and makeup until this is cleared up. Also, after brushing teeth use the alcohol to dab the bristle end of the toothbrush.
Hope this has helped.
Remedy for treating cheilitis.
My 7 year old had terrible angular and over cheilitis. It extended at least a centimetre from the lip line towards her chin and beyond each side of her mouth. It started nearly three weeks before this treatment before getting as bad as it did. It was like a peeling, scaly, crusting rash. I had thought it was just chapped lips so gave her Carmax or Vaseline before trying neosporin but it continued getting much worse. After researching and realizing it must be cheilitis, I bought tubes if lanolin (in the baby/nursing section - used for nursing mothers nipples) and a tube canestan ( yeast infection cream). I applied the lanolin liberally during day and dabbed canestan mixed in with lanolin at night and by day three she was so happy that she could open her mouth wide and it looked significantly healed. Now she regularly uses lanolin to protect, prevent and heal.
