Phytophotodermatitis, also known as "lime disease" (not to be confused with Lyme disease), "Berloque dermatitis", or "Margarita photodermatitis" is a chemical reaction which makes skin hypersensitive to ultraviolet light. It is frequently mistaken for hereditary conditions such as atopic dermatitis or chemical burns, but it is caused by contact with the photosensitizing compounds found naturally in some plants and vegetables like parsnips, citrus fruits and more. Symptoms include burning, itching, stinging and large blisters that slowly accumulate over time.
