What's the difference between sagging and wrinkles?
With age the skin "stretches" and suffers from the effect of gravity. On top of that, it gets dehydrated.
The result is that the surface of the skin increases, but the face doesn't! There's an excess of skin that nerves and muscles attempt to keep in place and that's the phenomenon of skin sagging.
Wrinkles have multiple causes: exposure to UV rays, damage caused by the environment, dehydration, etc. They're made worse by all the expressions we make such as smiling, squinting and frowning. The constant stretching and unstretching disturbs the collagen fibres. The skin gets marked more easily and wrinkles start to appear.
