Whether frozen or on the rocks, margaritas can be a refreshing summer cocktail, but they may lead to more than a potential hangover. A dribble of citrus juice on skin that’s exposed to the sun can quickly lead to a nasty burn called phytophotodermatitis — sometimes known as margarita dermatitis. It happens when a photosensitizing compound in limes called furocoumarin — also found in other citrus fruits as well as parsley, dill, celery, and a number of other plants — becomes activated by ultraviolet A (UVA) light, causing a burning rash within hours.

You may develop blisters or red, itchy patches on your skin, with symptoms at their worst within two to three days. Since only the areas of your skin that came in direct contact with lime juice are affected, the rash may appear as drips, streaks, or other irregular patterns. As the blisters heal, your skin may become darker (hyperpigmented) — an effect that can take months to go away. Ask your doctor about using a topical steroid cream and a cold compress to ease the pain.
