Eager to enjoy a refreshing poolside cocktail this summer? It’s important to be aware of the potential harm that a lime wedge can cause to your skin.
This seemingly innocent lime or margarita burn is actually a serious skin reaction caused by lime or other citrus juice coming into contact with bare skin while exposed to sunlight.
To ensure your safety during your next outdoor happy hour, here’s what you need to know:
Understanding Margarita Burn
According to Dr. Samer Jaber, a board-certified dermatologist at Washington Square Dermatology in New York, a lime or margarita burn is a skin reaction known as phytophotodermatitis. This reaction occurs when furanocoumarins, compounds found in plants, make the skin more susceptible to UVA light.
The result is a red, itchy, and blistering rash in the areas where lime juice has touched the skin. The rash may appear irregular in shape or as streak marks from the dripped juice.
In addition to citrus fruits, celery, parsnip, and even a plant called giant hogweed can also cause this reaction.
Who is Prone to Lime Juice Burns?
Although anyone can experience phytophotodermatitis, individuals with light or red hair or those who easily get sunburned may have a more severe reaction. The intensity of the rash also depends on the amount and duration of exposure to lime juice and the sun.
If the exposure is limited, the rash may be mild and last for days to weeks. However, prolonged exposure may lead to severe, painful, and blistering burns that require medical attention. The Centers for Disease Control and Prevention explains that the reaction can leave behind linear, brown hyperpigmented patches that take weeks or months to fade.
Some patients may experience long-lasting hyperpigmentation for years.
Treating Phytophotodermatitis
If you have phytophotodermatitis, treating it is similar to treating a sunburn. Dr. Jaber suggests using anti-inflammatory medications like Ibuprofen for pain relief, healing ointments like Aquaphor or Vaseline to promote skin healing, over-the-counter hydrocortisone ointment, and avoiding sun exposure. For severe cases, consulting a dermatologist for proper medical management is advised.
Fortunately, phytophotodermatitis can be easily prevented. Dr. Jaber recommends washing your hands with soap and water if you come into contact with citrus juice, using a high UVA protection sunscreen, and seeking shade when outdoors. Gardeners can protect their skin by wearing gloves.
