What Are the Different Types of Photosensitization Reactions?
There are two main types of photosensitization reactions: phototoxic and photoallergic. Phototoxic reactions occur when a photosensitizing agent directly damages skin cells upon UV exposure, resulting in symptoms similar to a sunburn, such as redness and blistering. Photoallergic reactions involve an immunological response, where the skin develops an allergic reaction to the photosensitizing agent, often leading to eczema-like symptoms.
