And as that fat disappears or diminishes, that affects the volume of the face and that affects wrinkling.

So that you cannot change.

That's kind of inherent in aging.

But the thing that we can affect, and we're going back again to ultraviolet light, ultraviolet light affects collagen and fibers in the skin called elastic fibers.

These are the fibers that are used to maintain the integrity and shape of the skin.

And ultraviolet light will damage the collagen fibers and elastic fibers in the skin.

you damage elastic fibers, you lose the stretchiness.

If you picture a pair of elastic clothing, you stretch the clothing, you let go and it snaps back.

That's what elastic fibers do.

If you damage them,

The skin doesn't snap back as fast.

It tends to sag and wrinkle more.

Also, the collagen, which maintains the shape of the skin, will be damaged.

The other thing aging and ultraviolet light will do, there are two layers of the skin, the epidermis, the very thin layer on the surface, and the dermis underneath.

The top layer of the skin, the epidermis, will thin.

And as it thins, it tends to wrinkle more and it tends to lose water more easily.

Part of the skin's job is to keep the water in your body.

And that's why as you get older, your skin can get

drier, peel more.

It's one of the reasons why you tend to moisturize more.
