Treatment: The goal of therapy is to discover and remove the exogenous heat source. Once the heat source is removed, most of these rashes slowly fade away over months. Some of the hyperpigmented areas may persist, however. Use of emollient creams or Kligman’s formulation has been reported. Kligman’s formulation includes a retinoid, a steroid, and a skin-lightening cream. Laser therapy has also been used to decrease the pigmentary disturbance.
