Have you ever met someone you knew from years ago only to ask yourself how come they look so old? I remember one guy that I knew from a former job, who was only in his late twenties, looked decades older. He smoked, drank heavily and used illegal drugs. All of those factors contributed to his aged facial looks.
So the best anti aging products are to simply not use tobacco, alcohol, and recreational drugs. Take care of your body and you will save money on not buying beauty products to repair damaged skin from premature aging.
