True, but confidence is a huge one. If your confident in your own looks so will you look ten times better then someone who's depressed.
Importance for facial attractiveness by Smirnoff
1. Confidence, just by taking a selfie on a low day vs a good day so is it a huge difference, the face just molds to perfection when your really confident in yourself.
2 Weight/bodyfat makes a huge difference on the face attractiveness and shows the features.

3. The jaw, everything most start with a symmetrical/strong jaw. It's point less to go for a nose job if the jaw is lacking, the base structure must get corrected first.
4. Eye shape and "depth", brows that match the eyes.
5. The nose needs to be in harmony with the rest of the face, match the overall structure.
6. Mouth, lips and teeth, a straight white smile. Says it all.
7. Skin texture, acne free.
8. Hair thickens, and a straight hairline on men.
My list is made for "normal" looking people, if you would have an extreme case of something on the list so would that of course be you nr1 priority.
