Did you ever notice how "bubbly" the soaps are from the big box stores, drugs stores, etc.? This is not at all natural and only occurs because there are foaming agents added. Soap also has a bad reputation because these kind of "soaps". Did you know that most commercial soaps actually remove the glycerin in the soap and in its place put in a detergent?! This, of course, makes skin very dry and they sell the glycerin back to the consumer in the form of a lotion to ease the dryness. Take a look at the name of the products as well. REAL soap is called soap, but a bar cannot be called soap if the glycerin is removed, so it is instead called a "beauty bar" or "bath bar".
REAL soap is not really bubbly, but rather it has a wonderfully, silky, creamy lather that feels good on your skin both while you're using it and afterwards, as it will leave your hands soft, not dried out.
It's like that old saying: "once you've tried it, you'll never go back!".
