Why do black people get fewer wrinkles than all other races?

it's to do with the layer of collagen beneath the skin which keeps the skin plumped up. with black people it is much thicker the lighter or fairer skinned a person is, the thinner the layer of collagen. take red heads for example they appear to age much more quickly ie: more wrinkles than someone with darker skin. which is why cosmetic surgeons use collagen fillers to plump up lines.
