As skin ages, elastic fibers in the
dermis break down, collagen fibers get "stuck" together,
and there's a gradual loss in hyaluronic acid, the ground
substance that gives skin its bulk and feel. The skin becomes
stiffer and less elastic, and when subjected to repeated movement
by the underlying muscles, such as in the forehead, and around
the eyes and lips, wrinkles appear. Exposure to the sun greatly
accelerates this process, and it occurs earliest in patients
with thinner, lighter skin. The principal changes seen in
the aging face include:
- Skin
changes, blotches, discoloration, textural changes
- "Mimetic"
wrinkles caused by movement of muscles
- "Furrows"
caused by loss of elasticity and laxity of underlying muscles
and ligaments.
-
Sagging and jowling caused by loss of underlying fat cushions
and skeletal structures.
There is no single technique that can correct all of these
changes, but a systematic approach to treatment can significantly
and often dramatically improve the aging face.
