I like makeup that is applied moderately 
Common cosmetics include a lot, but I just use lipstick and rouge.  Less is more.
Cosmetics are substances or products used to enhance or alter the appearance of the face or fragrance and texture of the body. Many cosmetics are designed for use of applying to the face, hair, and body. 
I'm leery of some, because they can be made from crushed up insects or even RUST!
That is true. Heavy makeup are deceptive to men
Yes, and in cosmetic commercials they give false impressions of what makeup can truly do, so even women are decieved.
That is true. Some people go as far as doing cosmetic surgeries to enhance their already pretty faces    
I'm sure it goes back to first impressions to determine how people are treated.
You are right.
It takes just 1/10 of a second for us to judge others and make that first impression.
