undoing redirect - the present content does define the very narrow concept of allergy (type 1 hypersensitivity) to molecules activated by light
'''Photoallergy''' is a form of [[allergic]] contact [[dermatitis]] in which the [[allergen]] must be activated by [[light]] to sensitize the allergic response, and to cause a [[rash]] or other systemic effects on subsequent exposure. The second and subsequent exposures produce photoallergic skin conditions which are often [[eczema]]tous.
