What is hand dermatitis?

Hand dermatitis is the term for irritation, inflammation and a rash of the skin on the hands, often including the fingers.

Drug-Induced Photosensitivity Definition

Drug-induced photosensitivity (light or sun sensitivity) is defined as skin inflammation caused by the combination of sunlight and certain medication. Drug-induced photosensitivity causes redness (erythema) and sunburn-like appearance of the skin. Both drug and light are required to cause drug-induced photosensitivity. It is the ‘photoactivation’ of the chemicals in the skin that causes the rash. The reaction between the light source and the photosensitizing chemical or medication can be divided into two types – phototoxic reaction and photoallergic reaction.
