I'm worried about my looks.

1. Why don't you put on cosmetics on your face?
2.Why don't you eat sereals and brown rice?
3. Why don't you do a plastic surgery?
4. Why don't you make double eyelids?
5. Why don't you have a double eyelid surgery?
6. Why don't you try to lose weight?
7. Why don't you eat less in the evening?
8. Why don't you remove fat from your body by exercising?
9. Why don't you focus on studying? You have a good personality.
10. Appearance is not everything. Why don't you find the way to earn money?
===================
Would you correct unnatural sentences, please? Thank you.

1. Why don't you use cosmetics on your face? or Why don't you put cosmetics on your face? The use of the word "on" twice is redundant.
2. cereals is misspelled.
3. "a" is unnecessary. "Why don't you do plastic surgery?"
4. I don't know what that means.
5. Again, "a...surgery" is awkward. The "a" is not needed. Surgery is already singular, you don't need to specify "a" or "one".
6, 7, 8, & 9 need no improvement.
10. "Why don't you find A way to make money?" "the way" implies that there is only one way to make money, when we know there are many ways.
