It's all fun and games until your poolside margarita causes a legit chemical burn. Phytophotodermatitis, also called margarita burn and margarita dermatitis, causes painful blisters when UV light and certain vegetables or fruit (limes are a popular offender) come in contact on your skin. And it's not pretty.

According to Good Housekeeping, the photochemical reaction that happens causes "cell death" (um, YIKES) and a variety of other symptoms, including blisters, redness, burning, and pain. And while, yes, citrus fruits are major culprits, celery, wild parsnip, parsley, hogweed, and more contain the furocoumarins that spur the condition.



"It only develops in areas where the chemical touches the skin, explaining odd shapes like streaks or dots where lime juice may have dripped down the skin or splashed," director of cosmetic and clinical research at Mount Sinai Hospital, Dr. Joshua Zeichner, told the outlet. "The initial rash is fiery red, and it often heels with a dark brown black."

Before you freak (because what is summer without margs??) there are ways to prevent it. Namely, avoiding contact by wearing gloves and washing up thoroughly after handling. But if you do develop Phytophotodermatitis, there is treatment. Topical steroidal creams are recommended for moderate blisters, inflammation, and itching, while more severe cases will require an oral corticosteroids or antihistamines.

And while, clearly, it's not fun, as long as you take proper care to avoid scarring you should be fine. "It only rarely causes any permanent changes to the skin," Dr. Zeichner added. But also, I might keep my drinking activities indoors for now.
