Margarita Sunburn

If you’re planning to indulge in outdoor entertaining this summer, you’ll want to know about phytophotodermatitis, also known as the Margarita Sunburn. As innocuous as this popular citrus fruit drink sounds, its consumption can result in surprisingly serious chemical burns and rashes. Limes, lemons and other foods such as figs, celery and grapefruit, contain a compound called psoralen, which when ingested, can result in severe sunburn and skin irritation upon exposure to UV light. Like some topical medications and oral drugs, the psoralen in lemons and limes can make the skin sun-sensitive. However, unlike medications, citrus fruit don’t come with a warning label.

Overindulging in margaritas and subsequent exposure to sunlight may result in a rash or red skin irritation that turns brown over time. Even individuals who are not imbibing can be susceptible to phytophotodermatitis. Bartenders, cooks, kitchen staff and chefs who regularly handle limes and lemons and then expose themselves to sunlight can be left with painful blisters and burns on their hands. The best way to avoid this chemical reaction is to wash hands well after handling foods that may cause a reaction to UV light. Gloves may also be a good idea if the combination of psoralen and sunlight are unavoidable. It goes without saying that the application of a good, broad spectrum sunscreen (like Anthelios sunscreens) is wise as well.

As with any burn, it’s best to treat it immediately. For less severe reactions, drinking fluids, a cool water bath and the application of aloe vera gel or a dedicated sunburn product can help soothe and moisturize the skin. For more serious cases that include blistering, peeling and fever, your best bet is to consult a professional who may prescribe topical antibiotic ointment and pain relievers for any swelling and inflammation.

On a side note, sipping on too many alcoholic margaritas can also impair your judgment of time and when to reapply your sunscreen! Call it a double whammy. It gives “enjoy responsibly” a whole new dimension.
