I'm gonna have to go with my initial statement...Is the skin the largest human organ?

Now I will agree that there are a number of factors that come into play when accounting for absorption and permerability of the skin. And yes, cosmetics, as well as topical ointments, salves and such do require a carrier that assists in penetration of the top layers. This is also a factor in where the item is to penetrate, i.e., topical delivery or deeper as for muscle and joint items. Aloe vera is one of the best. It just needs a good preservative to keep it from going old too quickly...longer shelf and usage life.

But as far as the skin absorbing pollutants or undesirable items in water via the shower, lets just use simple logic and consider it a valid point.
Now go rub some garlic on you palms and see how long it takes you to become..."fully fragrant"...;)

Preservative?

Cut piece of frond off of plant, rub on. The preservative (magnesium stearate) is toxic.

It was not the first part that was extreme by the second,

and it absorbs whatever is in your water.

"Whatever" is more than what is warranted.

But thanks for the light it provided.
