At what age did you see your appearance turn for the better?

This one's a bit long:
As a teen, my family was broke, so I had crappy clothes, dry hair, thick eyebrows, and even thicker glasses. My appearance took a turn for the better after I graduated high school because I was able to get a job and bought things to improve my appearance(new glasses, better clothes, better hair care products, purple hair color, etc). Unfortunately, I was also able to afford to eat good food as well, so I ate myself into an unattractive, overweight state. I stopped overeating and my appearance has now took a turn for the better once again. It's not a pretty appearance, but it's better than what I used to be. Though I fear it might go back to what it used to be due to the facts that my stomach is a bottomless pit, eating like a normal person leaves me hungry all the time, and I haven't found an appetite suppressor that actually works on me.
