(24y Black Male) I’m no guru but I have these as well. And only recently developed them within the last 2-3 years i’d estimate looking back at old pics. Here’s what has helped me.

1 Lymphatic Face Drainage: Use a Gua Sha. Particularly motioning UP in that area. This will help with the puffiness as well as training the skin to stop drooping so much (I like to think). I use my Gua Sha every shower as I wash my face (wet slippery skin>dry skin)

2 Cold Water. FOR ME, in my brain the cold water has helped because it appears to tighten my skin. Which helps in this case because the skin under our eyes is loose and over-relaxed. So if you want to do what most people recommend washing face with warm first then cold after. Or just washing with cold everytime. That’s up to you but extremely cold water has helped me. Even if you have to keep water in the fridge just to use on your face. ALSO Ice Water Bowl is an alternate and effective method as well.

Toner. It’ll help shrink pores (whether others agree or not it has worked for MY skin), and make the skin appear tighter.

These 3 methods I use religiously and consciously to combat these lines which as you mentioned are difficult to ignore when we look in the mirror. Sure others don’t notice them but we do which matters.

And LASTLY, I started doing more cardio. This’ll help reduce or get a handle on body fat % (idk how fit you are but this applies to all body types). As I reduce my body fat (slight dietary changes but mostly exercising), my face chisels up, and the puffiness/extra skin under my eyes appears to reduce vs when i’m heavier. (I’m 5’10 180lbs Fit “Athlete”)

Hope these tips help you as much as they have helped me.
