Dear Wrinkled Julie:
Now skin is a very cool story! Did you know that your skin is made of layers upon layers of skin
cells? New cells are constantly growing from below and pushing older cells slowly to the surface.
As these cells get older, and further from the things they need to stay alive, they begin to die.
As they do, they get dryer and dryer and thinner and thinner. Layers of these skinny dead cells lie
in overlapping stacks on the surface of your skin until they flake off and float down through the
air.
Places like your fingertips and the soles of your feet have an especially thick layer of dead
cells. When you take a bath, these dead cells begin to plump up from the all the water. After a
while, they have so expanded that they no longer lie flat next to each other. And you become
wrinkled like a prune!
When you get out of the tub, and those dead skin cells dry out again, the wrinkles disappear!
Voila. You're young again!
Signed,
Wendell
