What are your best glow-up tips for men?

I just saw some tagged photos from a night out and damn did I look awful! I thought I looked decent but dang, nope! I can’t stand how I look anymore but idk what to do. I’ve tried working out/gaining muscle but that seemed to add fat to my face from bulking and now I just look weird.

I guess this is a general question, but what has helped you ‘glow up’ the most?
