Diaper rash is caused by the combination of a tight and moist environment that affects the skin's barrier function. Urine and feces can also be irritating. When the skin barrier is disrupted, it can also affect the skin's flora. Some individuals develop a fungal infection in the rash. In such cases, the standard measures for diaper rash may not be as effective, and it may be necessary to consult a dermatologist or general practitioner for evaluation.
If the rash is severe or does not improve with the mentioned measures, further intervention may be necessary, including treatment for infection.
