There is nothing wrong with enjoying a margarita, but be careful when drinking and sunbathing. “Margarita dermatitis” is scientifically known as phytophotodermatitis which occurs when sun-sensitizing ingredients like psoralens on the skin are exposed to the sun. “Psoralens are natural compounds found in limes, celery, parsley and other vegetables and fruit acids” (Ross, 2013). Psoralens cause the skin to be highly sensitive to the sun by acting like a sun enhancer which can lead to blistering, sun poison, hyperpigmentation and skin cancer.
Phytophotodermatitis can be treated with topical steroids, if it is identified within 24-48 hours. Hyperpigmentation may fade naturally, but it may take weeks to months for the skin to return to even complexion. Be careful when consuming any alcoholic beverage while in the sun because alcohol can cause dehydration in the body. Avoid the use lotions and creams that contain bergamot essential oil or other citrus oils as well as perfumes. All of these ingredients act as sun enhancers and can cause the skin the burn.
