Now it's time to put an end to this bathing session. This is usually
the moment where you discover your strange fingertips. They are
now all wrinkled and they feel odd. Obviously something has happened.
This marvel of nature named skin is very complex. Its purposes
are multiple. As the first link between the body and the external
world it has to ensure :
- chemical and bacterial protection
- thermal regulation
- absorption of shocks and vibrations
- protection against the sun
- and very important : allow feeling.
| Skin structure is made of 3 layers, epidermis, dermis
and hypodermis. |
 |
| Back to the weird fingers. After more than 30 minutes
in the tub, the epidermis has absorbed a lot of water. But
the dermis, which is deeper, has not absorbed as much. |
 |
| 
The epidermis has swelled. If this inflation were uniform
(the same everywhere), the finger would just be fatter.
|
But the skin is not uniform. It is tensed in the direction
of the length of the finger. Therefore, the epidermis inflates
following that direction. And if you look closer, your toes
wrinkle as well. |
