If you get it on your body it wont cause any serious damage. But dont try to put it on your body on purpose because its not good for it.
If not removed properly, or maintained they WILL damage your existing nails. They can make your nails brittle if you peel them off yourself.i find gel nails, to be not harmful when they are on but...
Acetone, Formaldahyde, Toluene, Dibutyl Phthalate. ETC.
You can usually find nail polish in a place like Rite Aid or Longs in the beauty section.
