Well, having a nice fruity cocktail on the beach can be perfect, however, be aware of the fact that if it contains lime juice, rather do not spill it on your skin. Why? You perhaps do not know about this, but phytophotodermatitis is a real medical condition which occurs when you lime juice gets on your skin and then it is exposed to the sun.
What happens then? A very ugly, itching and painful sunburn, just like these ones in the pictures. Well, I guess that drinking margaritas outside during the summer is not so appealing afterall?
