Mechanisms of phototoxic and photoallergic reactions

Abstract

Solar radiation represents an important environmental stress for human skin. The biological reactions resulting from this interaction leads to physiological and pathological reactions such as an increased photosensitivity. The present chapter focuses on the mechanisms underlying photosensitivity, especially phototoxic and photoallergic reactions caused by exogenous and endogenous chemicals, especially drugs. © 2011 Springer-Verlag Berlin Heidelberg.
