  • alone without contributing factors (idiopathic photodermatitis)
  • in combination with an ingested or externally applied medicine
  • in combination with a chemical substance on the skin (e.g. phytophotodermatitis associated with plant contact)
• UV radiation may also trigger certain skin conditions or worsen their symptoms.
