The visible signs of aging cannot be fully avoided, but can be
dramatically minimized. As far as the skin is concerned there
are two types of aging — intrinsic and extrinsic. Intrinsic
aging involves the inevitable; as we grow older, our skin
naturally becomes thinner and drier. Diminished amounts of
collagen make the skin less elastic. What used to bounce back
begins to sag. Static, deep wrinkles may begin appearing. The
rate of these events is genetically determined for each person;
the process first becomes noticeable between the ages of 30 and
35.
