What should i do to take care of angular cheilitis?

Perleche: Combination of a topical corticosteroid usually works along with an anti-fungal that covers candida. Apply apple cider vinegar (raw unfiltered organic) after the shower, let it dry, then apply cream.

Steroid cream: Angular cheilitis could be a sign of vitamin or mineral deficiency including iron. Consider evaluating your diet and vitamin/mineral intake and consider seeing a dermatologist if it doesn't clear up for a steroid cream or other treatment.
