Cosmetics - an introduction.

I don't know any woman who doesn't like using cosmetics. There are plenty of choices on the market and we can easily buy a personal care products all over the world. It seems that nowadays we are go crazy over them, however cosmetics have existed from for ages. What is the point of applying in aplication of cosmetics? Do we really know what is inside of that cute package, and how does it interacts with our skin? What ingredients are good for us and what are harmful? I would like to introduce you to the a main ideas of usage using cosmetics, knowledge about ingredients, raw materials, cosmetic chemistry, skin properties and a generally wide range of cosmetic science topics. Probably most of you know how it works, but I would like to invite you to follow my notes, ask a questions and discuss. I will try to update as much as I can. I count on your attention, and any questions will be a motivation for me. :)
