Well, I never!!

I loveeee me some tequila and maragaritas are one of my fav drinks...but you gotta be careful of MARGARITA DERMATITIS

Never heard of it?  Me either but it sounds funky.

According to "Shape" magazine, if you get lime (from the marg or whatever) on your skin & it is exposed to the sun...it can result in your skin turning brown/purple and EVEN blister.  Some say it looks like poison ivy.

ARGHHH!!  Foul.  If it's ID'd in the first 24-48 hours, a steroid can treat it.  Otherwise you gotta let it fade on it's own, which can take weeks to months!  Not cute. 

Keep the lime off your skin and on the rocks ;)
