Phytophotodermatitis is a reaction that occurs after exposure to plants and ultraviolet radiation.

What does it look like?

Phytophotodermatitis appears as red vesicles and even blisters that leave profound postinflammatory hyperpigmentation in bizarre shapes where the skin touched the offending plant. Linear lesions and swirls are quite common. Common triggers are lemon, lime, hogweed and fig.

How is it treated?

No treatment is necessary.  Over time, the hyperpigmentation will fade.
