Photosensitivity is when a person’s skin is very sensitive to sunlight. This may produce rash on the affected skin part which is also known as photodermatosis. Patient may not associate their skin complaint with exposure to light. It is not always the bright summer sun which is responsible; some people also react to sunlight in winter and very sensitive subjects may even be affected by fluorescent lamps indoors.
