A note to people enjoying margaritas outside this summer you may want to be extra careful not to spill anything on your skin.

Really, really careful.

Buzzfeed brought our attention phytophotodermatitis; a chemical reaction that can occur when lime juice mixes with UV rays—something that can certainly happen when drinking outside.

Check out some Instagrams of sad people who learned about this the hard way.

If it gets on your skin, lime juice in the sun can cause burns, although, “The severity obviously depends on the amount of juice from the lime that is on your skin and amount of time that is there. It is best to avoid this at all costs,” says Elisabeth Thieriot, a skincare expert, who founded Replete Skincare.

Most people don’t notice the burns right away. In most cases, you don’t see the burns until a couple of days have gone by. “At times, they last up to several weeks or even months with an unattractive appearance. Something as simple as drinking a margarita can cause this if the drink splashes on your hand and you don’t immediately wipe it off with a wet towel or napkin. Usually topical or oral steroids can reduce the blistering and inflammation to go down. If this happens, please make sure to get it treated - as in some cases hyperpigmentation can occur,” says Thieriot.

What an evil world we live in when margaritas and sunshine, two of our favorite parts of summer, become a potential danger to our health.
