Quote:

"Some parts of the body have a thicker skin than other parts. Hands or the soles of the feet tend to be thicker. Typically, it is more difficult for these areas to absorb chemicals into the body, whereas the thinner areas are more prone to absorption into the body. Regardless, the skin absorbs chemicals. An example is that people use creams or oils to soften the skin. Some individuals who are alert to chemicals can actually "taste" the chemical which is placed on the skin. It is unpleasant to be alert to the tastes of some compounds on the skin, so we often "shut out" that sense. You can even conduct your own experiment to test the validity of skin absorption by placing garlic in your socks and later sensing the taste in your mouth."
