Phototoxic
; photoallergic
When a photosensitizer is activated by UV radiation, energy is transferred to the surrounding tissue after it has been absorbed. The cell damage triggered by this is called phototoxic dermatitis.
A photosensitizer can be plants (e.g. meadow grass dermatitis), perfume (Berloque dermatitis) or systemic drugs (e.g. in PUVA).
In the area of UV-exposed localisations, erythema and possibly also blisters occur. Post-inflammatory hyperpigmentation may occur
