"Our hands are so much a sign of our age that we should learn to tend to them better in our 20s," said Dr. Linkner. Like the eye area, the skin on your hands is thinner, making it more susceptible to ageing, which is why she says finding a quality moisturiser can help keep them looking great. Check the label to ensure the formula has hydrating ingredients (like hyaluronic acid or ceramides) and no harsh chemicals.
