To treat diaper rash, after cleansing and ensuring the skin is dry, gently apply enough to cover the entire diaper area, even in areas that may not look red and irritated because irritation may not be visible always. Rub it well using your fingers. To protect your baby’s skin from further irritation, apply Diapex cream at each diaper change to soothe the irritated skin. Protect your baby’s tender skin with the best diaper rash cream.
