Asalam0alikum.i have black marks at the corners of the lips its look like angular chelitis but there is no pain n bleeding.plz tell me cure.

Multiple: Wa-alaikum-salaam it can be due to lip licking, B12 deficiency, smoking, overexposure to sun or post inflammatory hyperpigmentation. Take some B12 supplements and avoid lip licking.Apply a good lip balm and sunscreens with spf 30 1/2 half an hour before going out in sun. If still the symptoms do not improve then pls get a clinical examination done by a dermatologist.Bacterial and fungal infect.
