I am 50 (well, 51 tomorrow) and whereas genetics do come into play I can tell you this:
My skin is now soft, my hair is now soft, my eyes are CLEAR, and I look younger. What I thought was nothing more than the effects of age were the product of alcohol. Sure, I still have some fine lines but they're easily covered.
Just a note, I only drank on Fridays and Saturdays.
