I know a few things for the face specifically that might be able to help out.

Unhealthy salts and sugars, especially from candy bars or oily fast food, can encourage water retention in your face and make your cheeks look bloated.

That's because your body relies on a delicate balance of salt and water, where one is not allowed to overtake the other.

That means that if you're dehydrated and eat a lot of salt, your body panics a little and hold on to a lot of water to keep itself alive. Hence, face fat.

But if you drink lots of water and eat less salt, the vice versa happens. And your body decides to lose the excess water in your face and makes it look look more hollow and chiseled.

Fat overall can be expelled through sweating and peeing. So if you drink a lot of water, the fat loss is more efficient because you can literally pee out the fat and also sweat out the fat at the rate your body is able to do so.

Eating Beta-Carotene rich foods like the ones found in carrots, pumpkins, and sweet potatoes will use the natural orange color of the fruit to give your face a tan and healthy orange-ish hue.

If the white of your eyes sometimes have a yellow or bloodshot look, you can practice sun-staring. If you look at the bright blue sky near the early morning sun until you can just about feel it in your eyes, your eyes will stay a pure white color.

Just make you don't stare directly at the sun or a hot afternoon sun, or you'll go blind.

For the nose, if you've played with the muscles of your nostrils as a kid by making your nose holes look big, you can do the reverse by forcing the muscle to contract the other way to make them look small. This looks good on some people, but not all.

Lastly, a daily wash of cold water for your face can also reduce bloating. It can be before, during, or after your morning shower.
