I'm 35, but my hands and forearms look much older. My fair skin ages faster than normal in response to sun exposure. (In constrast, the skin on my stomach is smooth.) First noticed my hands looked older than normal when I was nine.
At one point, I was 80 lbs heavier than now, but I lost the weight slowly and have kept it off for 4 years. If I pinch an inch of skin towards my underarm, the tops of my arms look somewhat normal. Any ideas for treatment? Even when it's 100 degrees out, I wear long sleeves.
