I am 86,and have great looking hands(with a FEW wrinkles!) and my wife and I swear by Evening Primrose Cream,a bog standard one from Boots is fine,don't go mad on the expensive ones!
It won't get rid of the wrinkles completely BUT because it has a great softening effect on the skin, when you move your hands etc,the wrinkles don't "bunch up" and look apparent.
It also "bleaches" out any of those annoyuing liver spots too.
If you stick to one of the cheap Evening Primrose creams and it happens NOT to work for you,then you haven't lost anything.
Give it a try,it can't hurt.
