How Olive Oil Cleans Your Skin
Oil attracts dirt. When you rub olive oil on your body, the dirt attaches itself to the oil. When you wipe away the oil, the dirt tags along.
It doesn't take much to turn olive oil into soap. Soap is just oil (or animal lard) mixed with a chemical to make it wash off with water. Of course, you end up washing away all of your skins natural oils too. You are left with skin that is just too clean, because you are no longer protected by natural layer of oils and healthy bacteria.
How Olive Oil Protects Your Skin
Olive Oil contains polyphenol compounds that act as antioxidants to help prevent and repair damage to the skin done by accidental sun exposure. The skin damage is related to the destructive activity of free oxygen related radicals produced by skin cells. Polyphenolic components of olive oil have been compared to traditional antioxidants, such as tocopherols, used by the cosmetic and pharmaceutical industry to prevent skin damage. Results show polyphenols as having the highest activity as radical scavengers. [http://www.oliveoilsource.com]
