화장, 화장품와 메이크업의 차이가 무엇입니까?
Hello, I'd like to know the differences between "화장", "화장품" and "메이크업"
Thanks!

Question

Answer

화장 = makeup
화장품 = cosmetics

You will come across many nouns ending with "품(品)" which means "article", "ware", "goods"
식품: food
제품: product
상품: merchandise
모조품: imitation
공산품: factory made goods
수제품: hand made goods

Answer

"화장" is same with "메이크업(makeup)". "메이크업" is a naturalized words.
"화장을 하다" or "메이크업을 하다" . It means "wear makeup" 
"화장품" is a cosmetics such as lipstick,r powder, etc.
