Pidgiepoo-------I guess to each his/her own but your lime idea reminded me of a friend of mine who was "blotched with streaks" for months.......and I do mean months! She thought something had caused it in the water, but soon realized she was dripping lime juice down her legs at the bar she spent the afternoon at (in the sun). I figure no one would believe me so I googled and got this.......see below and YMMV.
[h=1]Watch out for lime juice or you could get 'Mexican beer dermatitis'[/h]Beware of the lime slice, if you're a big fan of Mexican beers or a bartender serving them. That beer and the juice of an accompanying lime could create a potent combination for your skin called "Mexican beer dermatitis."
Dermatologist Dr. Scott Flugman, of Huntington Hospital in New York, reported in the Archives of Dermatology that a substance in lime juice — if left on the skin and exposed to the sun — can cause the skin to discolor as if you've been stung by a jellyfish.
What's worse: The marks can linger for months.
The condition is often seen in bartenders who work outside, as well as boaters and beachgoers who are using limes in their Mexican beers or mixed drinks.
If the lime juice sprays on your skin that's exposed to sunlight, the area will first appear red before turning brown.
But it doesn't look like a tan, said Dr. Philip Shenefelt, an associate
professor of dermatology at the University of South Florida's medical school.
"Initially, it's red like a sunburn and then it turns brown, but it's blotchy and persists for a number of months," he said.
While the condition is probably seen only in the summer months in northern states, dermatologists in states such as Florida and California are more likely to see the condition year round, Shenefelt said.
"It's not uncommon," Shenefelt said. "We see it often in people who have beers with limes or mixed drinks out on boats" where they don't wash off and are exposed to sunlight for hours afterward.
The blotches can appear anywhere on the body — any place someone has touched their skin after having handled limes or lime juice.
The substance in limes that discolors the skin is called psoralen. It's also found in lemons and marigolds, but in lesser concentrations — so it's less likely to stain your skin.
To avoid the telltale spots, immediately wash lime juice off your hands or skin when it's exposed to sunlight, Shenefelt said. And stay out of the sun afterward
