We all pay attention when it seems like a new wrinkle or age spot crops up on our faces, slathering on expensive creams and serums to prevent aging. We use sunscreen prodigiously to make up for all those years when we worshipped the sun, but are we protecting the skin on our bodies that really show people how many candles are on the birthday cake? We're talking about your hands, and they're one of the most neglected areas when it comes to skincare. But the skin on your hands is one of the first places where the signs of aging tend to show up first. That's because the skin on top of your hands is among the thinnest, and it has very little fat and collagen to plump it up and repel wrinkles. Many women neglect their hands as they slather sunscreen on all of the other exposed parts of their bodies, resulting in brown spots - also known as the dreaded "liver spots." If your at-home hand care is limited to moisturizing dish soaps and the occasional pass with some drugstore lotion, then you need to amp up your hand care regimen.
