The so-called margarita rash is a skin condition that can occur when a chemical compound found in limes interacts with sunlight.
“Whenever you spill a margarita (or just lime juice) on your hand … and then that skin comes into contact with the sunlight you can develop this type of rash,”
Dr. Andrew Newman of Phoenix-area Affiliated Dermatology told KTAR News 92.3 FM.
The rash could cause scarring, but that’s rare, Newman said.
“The rash that develops is quite itchy at first and then it might get irritated and painful, potentially turn a dark red on your skin,” he said.
It’s not just lime juice that can cause the condition, known medically as phytophotodermatitis. Other citrus fruits and celery also contain the compounds, furanocoumarins, that don’t mix well with sunlight.
“Bartenders commonly get this, (also) people who are picking limes off of a tree in their backyard, or those who are out on spring break and making cocktails for themselves for recreation,” Newman said.
You can avoid the rash by being careful when mixing those drinks and staying out of the sunlight after handling limes.
“If you’ve already developed a rash and you’re needing some relief, you just want to get a little cortisone cream over the counter,” Newman said.
“Use it a couple of times a day and you’ll get some relief.”
If symptoms persist, contact a dermatologist.
