Description
As skin ages, collagen and elastin, fibers that keep
the skin firm, weaken. The skin looks loose and lax,
becomes thinner, and loses fat, so that it looks less
plump and smooth. While all these changes are taking
place, gravity is also at work, pulling at the skin
and causing it to sag.
Cause
The sun is the major cause of unwanted changes in the
skin with aging. How wrinkled your skin becomes depends
largely on how much sun you have been exposed to in
your lifetime. Cigarette smoking can also contribute
to wrinkles. Wrinkles also depend on your parents -
the tendency to wrinkle is inherited.
