Since a year I am suffering from this, around my mouth skin becomes dark after 3 days of it cracks comes at my mouth angles, skin becomes dry, then oozing starts. Then I have consult doctor, used omnacortil 10 mg and calcimax 500, continuous for 1 month, cetaphil moisturizer. Though I have used it I haven't got cured, so shill I stop using those tablets and seek for another doctor r else shill I continue.
