Certain photodermatoses such as photocontact allergies are triggered by photosensitizing substances while others are a result of systemic diseases such as metabolic disorders. Sunburn is not, however, a photodermatosis. It can occur in any person who is exposed for too long to high UV radiation and is primarily caused by the UV-B spectrum. On the other hand, a person with a photodermatosis is hypersensitive predominantly to UV-A radiation.

As well as avoiding UV light as a preventative, treatments available include ointments for local application and tablets. Therapeutic radiation with light can also be an option.
