I would actually just recommend using a regular thick hand cream like Cerave moisturizing cream or Biossance Omega Repair hand cream (my favorite) on top of the anti aging products you use on your face. I use my vitamin C, Hyaluronic acid, chemical exfoliants, and retinol on the back of my hands and then seal it in with a thick moisturizer. Make sure you are also using at least SPF 30 on your hands daily!
I love Aveda hand relief lotion, it was one of my first recommendations. Not only does it immediately hydrate and soften your hands, it's greaseless, and smells so good. I order it online but there are Aveda Salon Spas Nationwide.
