Why does weight loss from gastric bypass surgery make people look older?

Why does weight loss from gastric bypass surgery make people look older? I have a friend from high school who had the surgery and since she had it 8 months ago her face is more wrinkled and she looks much older than before she lost 100 pounds. I noticed that Star Jones looks so much older now than she did before her weight loss. She doesn%26#039;t look good at all. I will say that Al Roker looks no different in the face to me. Maybe it%26#039;s just women.

because people lose atipose tissue (fat) when they get older, and they wrinkle up. All that excess skin is there, it can only shrink so much...
