I utilize a compound that passes other molecules through the skin. It takes about 15 to 20 minutes just to reach the muscles and blood vessels below the derma.

I utilize a compound that passes other molecules through the skin. It takes about 15 to 20 minutes just to reach the muscles and blood vessels below the derma. It would then have to travel to the lungs. I would expect at least an hour or probably more if this were occurring. Even then you would have to rub it over a decent area of skin.
