toenail

while its not really made of skin like the other definitions said, its actually made of keratin, which also makes up your hair and (of course) your fingernails. also, as a side note, keratin is also what makes up rhinoceros horns

teacher: hey, kids, did you know that your toenails are made of magical candy?
gullible child: really?
teacher: no!
