Under eye area starting to look a bit lined and saggy - anything I can do?

[Lottapianos]

I'm 37 and my skin is in pretty good nick, but it is dry and dehydrated. I have noticed my under eye area looking drier and a tiny bit saggy and generally 'drier' than usual. I use serum and moisturiser every day but have never used an eye cream as I've read that they are no use. Diet is good, tons of fruit and veg, hardly any caffeine, sleep well, drink plenty of water, take it easy with sugar

Any suggestions? Thanks
