Red dots on baby’s arms and legs should be considered as eczema in children, which is an immune dysfunctional skin disease, mostly with red dots, papules and pimples. In terms of medication treatment, usually for milder symptoms, only dry skin or damage, you can choose non-irritating emollient moisturizers for topical use, like cod liver oil ointment and Eudragit ointment. The former of these two ointments does not contain hormone-like ingredients and will not produce side effects or drug resistance, while the latter is a hormonal ointment that should not be used for a long time. In addition to medication, children should pay attention to their diet and eat more vitamin-rich foods, such as fresh vegetables and fruits. Parents should also be gentle when washing the affected area to avoid causing local damage to the child.
