Two options. Further is the filorga hand fillers. It's a glove filled with serum you wear for a little while.
If this is too pricey then skin logic also has a great hand mask available at dischem and edgars and clicks. It's R99 and I wear mine and then pack it away well and reuse it twice more as it has so much serum in it.
Both will plump up your hands, restore moistur to your skin And condition your cuticles.
Try it. You won't regret it.
