A New York City woman is issuing a harrowing warning after her hands were left covered in agonizing second-degree burns following a seemingly harmless afternoon making margaritas. Haley Peacock, a Brooklyn-based designer, shared a now-viral TikTok documenting her experience with “margarita burn,” a condition triggered by handling citrus before heading into the sun. Haley Peacock suffered second-degree burns on her hands after making a cocktail last month at an upstate home. By the following day the consequences were undeniable: her hands had become alarmingly red, swollen, and intensely painful. “My whole hand is discolored,” she said, after receiving treatment for the second-degree burns at urgent care.
