I have dryness every morning I wake up and due to dryness lip cuts at corner of mouth , have tried applying hydrocortisone cream along with antifungal cream , have started b12 supplement too , things have improved but still keep getting back this cuts in 2-3 weeks it has been 5 months since this started , how much time this generally take to cure and not recurr , also does any food play any role in causing this issue like citrus food etc , also is this anything to worried about or its a normal thing
