If a margarita, bloody mary, or lemon drop is your favorite pool side drink, you may want to reconsider your choice to save your skin. The juice of certain fruits (limes, lemons and celery in particular) contains chemicals that react with the sun, and can cause phytophotodermatitis, or sun induced chemical burns when present on your skin. Using lemon juice to lighten your hair, or drinking cocktails with these garnishes can put you at risk. If you notice redness, hyperpigmentation, or blistering, try hydrocortisone cream to reduce irritation, or see your doctor for a skin tone evener. Or, more simply, just avoid fruits and herbs containing these chemicals that are also found in parsley, parsnips and dill. Swap out your margarita for a daiquiri, and be sure to wash your hands/skin with soap and water after handling any garnishes to eliminate any residue on your skin.
