For health, beauty and ecological reasons, as well as for the protection of our skin, bodies, and environment, both in the production and use of soap, there is no question that handcrafted soaps are superior to commercially produced soaps.
In fact, the sad truth is that most commercially produced soap is not really even "soap" but rather a chemicalized detergent bar. My personal opinion is that these anti-bacterial and anti-microbial aspects of commercially produced soap are a danger to every individual who uses them on his or her skin and a danger to the public at large for increased outbreaks of "superbugs".
Your body's natural defense to bacteria is your skin, which is the bodies largest organ. Your skin produces exterior oil cells which protect it by trapping dirt, bacteria, particles and so on. However, once the oil traps the substance, it cannot be removed by water alone since; 1) oil and water do not mix, 2) if your oil was easily removed, it would compromise your body's natural defenses.
That's where soap comes in. Without getting into too much detail and to keep this simple, as you use soap, the soap foam attaches and binds to the dirt, bacteria, and so on, so when you rinse off the carries it all away from your body.
This is how handcrafted soap gives a natural and fresh clean feel to the skin. Once you try it you won't go back to commercial soap again.
