I'm sure that you know that cosmetics are  products used to enhance or alter the appearance or fragrance of the body.
Yes, I know. I actually have a degree in cosmetology.
That's great!. I like the fact that  alot of them are made for applying to the face and hair.
Yeah, it seems that they are also becoming more diverse as far as skin tones, hair color, etc. are concerned.
Maybe, one thing that I have noticed is that  they are most often a  mixtures of chemical compounds; some being derived from natural sources 
I have noticed that, too. It seems that companies are becoming more aware of the dangers of harsh chemicals to the body.
I know you might have noticed that the most often seen cosmetics in the market are pstick, mascara, eye shadow, foundation, rouge, skin cleansers and others 
I have noticed that. I really like the fact that makeup has become an art form, instead of just a mundane part of a daily routine.
These days they cosmetic companies seem to have diversified into the production of  perfume and cologne as well
Yeah, a lot of celebrities have released their own perfumes and fragrances.
