Advice on reducing face puffiness?

My face feels puffy nearly every day, although I’m average weight for my height (male, 5’6, 138lbs), I exercise and eat low-sodium foods, avoid sugar and carbs, coffee, eat lots vegetables, and stay hydrated, but still feel like there is a layer of fat around my face. I say “nearly every day” because once in a while it goes away and my face feels “tight.” I’ve tried experimenting with food combinations, avoiding food groups etc. but wondering if I’m missing something. I’m in sales so it’s important to look my best, and I don’t feel like I’m reaching my full potential here. Maybe I just need to keep losing weight?
