2. Phototoxicity

Phototoxicity is also a form of photosensitivity. It is also sometimes known as photo-irritation. This is a chemically induced irritation that requires the presence of light. The affected area resembles an exaggerated sunburn.

The chemical involved can enter the skin through topical administration, oral ingestion, or parenteral administration (not through swallowing). The chemical involved will react to light and cause toxicity. This includes many cold-pressed citrus oils such as bergamot and plant juices such as lime and parsley.
