For the treatment of prickly heat, you should improve your baby’s living environment, keep your baby’s skin dry and clean, and use medication to treat it. Prickly heat is a disease that occurs in a hot and stuffy environment. If a child has a lot of prickly heat on the forehead, parents should help the child to ventilate the room by opening the windows, lowering the indoor temperature and humidity, helping the baby to keep the skin dry and clean, and avoiding the baby from scratching the affected area with his hands. In addition, topical medications can be used to treat the problem, such as glycerite lotion and prickly heat powder; if the baby scratches the prickly heat, resulting in localized epidermal breakage and infection, then mupirocin ointment can be applied to the affected area. During the treatment period, it is advisable to eat a light diet and avoid sweating a lot. If your child has a lot of prickly heat on the forehead, please follow the doctor’s instructions for treatment.
