I know there have been similar questions, but nothing has quite answered definitively.
Compared to ingesting something, how much does your skin absorb substances into the bloodstream? And what factors impact on this?
Does the type of substance make a difference? Lets say magnesium, you can ingest it in powder form, or you can rub it on your skin, which would be more effective in delivering nutrients to your cells and why?
I guess while on this topic, what about something like fluoride. I've read somewhere that you absorb more fluoride from having a shower than drinking 2 litres of tap water each day.
If someone could point me in the direction of something conclusive that would be great.

Many medications/treatments are applied by rubbing into the skin and are absorbed by the body. Some that are better utilized by avoiding the stomach (Progesterone and L-Glutathion are 2 off the top of my head.)
Weird experiment???after a shower (so your feet are wet) step into or sprinkle liberally salt crystals on your feet. In a very short time, you will taste the salt in your mouth. Shows how substances can be absorbed through your skin and travel throughout your body. It will make you much more aware of what you put on your body.

It depends on the size and type of the molecule, your skin (thick, thin, mucuous membrane) and probably a host of other factors. I apply hormone gels to the inside of my arms (where the skin is thin) and it works just fine.
I think the great advantage (or disadvantage in case of toxins) is that the stuff does not pass through your liver. I need my liver for the wine I drink, so I prefer the transdermal route, if possible. (Transdermal alcohol would bypass my taste-buds, so this is not an option.)
I do not think that you can get a general answer, like a percentage compared to oral delivery and I also think that individuals react differently.
