Your hands will betray your age faster than anything else and there is not a lot you can do to make them look youthful. The best strategy is to avoid doing things that cause people to focus on your hands. Ladies, get a manicure and wear polish, but avoid extremely long nails, eye-popping colors, and gaudy nail art. You can wear rings and bracelets, but do not make your hands the focal point of the ensemble. If anybody gives you a major diamond, have it made into a necklace. You do not need to walk around with any bling or with naked nails (that focuses attention, too), but as you age, you need to go to understated hands.
