I have puffy eyes and cold green teabags really do help after a little bit. I usually just set an alarm for 20 minutes, put them on and take a nap- the puffs are gone by the time I wake up. I'm sure the nap itself helps too.
i've heard cold masks, cold spoons, etc. i'm pretty sure you need stem cell lotion that costs a lot because it's all that valuable dead baby or really just surgery. i myself have "hollows" under my eyes so i cake on concealer under them.
