It is recommended to apply a moisturizing cream such as GLAXAL BASE or AQUAPHORE at least twice a day on the dry skin under the penis. Avoid hot baths or showers and use mild, unscented soap like Dove or Ivory. If the issue persists or if there are symptoms of a fungal infection, over-the-counter antifungal creams like clotrimazole can be used. If the problem does not improve, it is advisable to consult a doctor for further evaluation. It is important to note that healing may take time, especially in cases of dry skin or fungal infections.
