Skin rashes can occur from a variety of factors, including infections, heat, allergens, immune system disorders and medications. One of the most common skin disorders that cause a rash is Atopic Dermatitis, also know as Eczema. Rashes can also be caused by Psoriasis, drug reactions and infections.
At-home interventions, such as avoiding harsher soaps and detergents or other irritants and applying creams or lotions, can lessen symptoms or reduce the risk of flare-ups. Medicated creams or ointments can lessen symptoms.
