It's often hard for parents to distinguish between intertrigo and prickly heat, but our approach to handling them is generally the same: keep the area dry and apply a small amount of talcum powder to the area affected by prickly heat. Diaper dermatitis and prickly heat may appear similar. Diaper dermatitis primarily occurs on the baby's genital area due to the parents' failure to change diapers or nappies in time, leading to contamination of the skin by the baby's excrement, which can cause the appearance of erythema. Typically, the skin's surface will exhibit red patches or rashes. At this point, we shouldn't use talcum powder; instead, we should visit a dermatologist who will prescribe antimicrobial topical treatments. Another condition is atopic dermatitis, which also manifests with the development of a rash but is characterized by genetic predisposition and being primarily an allergic reactive disease. It usually appears on the face and the flexural sides of the limbs. If you notice that your baby develops rashes not just during summer but also in winter, or if the rashes appear sporadically, you should take your child to a dermatologist for an examination to see if it is atopic dermatitis. For managing atopic dermatitis, the routine care typically involves the long-term use of moisturizers instead of talcum powder and avoiding allergens.
