Where did you get those raisins on your fingers?
, the outer layer of the human integument
, is covered with a protective
oil, called sebum
. Sebum is secreted by the sebaceous
glands in the skin and acts as a lubricant
, giving the skin a somewhat solvent-resistent
quality. Sebaceous glands are not found in the epidermis of the palm
s or the feet
. When your fingers have been in a wet environment
for an amount of time sufficient for the sebum to be washed away
, the outer layer of skin begins to absorb water
. This extra moisture waterlogs the epithelial layer of the skin, causing some places to become protuberant
, making wrinkles that somewhat resemble 'raisins
' on your fingers. Your fingers are not, in fact, shriveled. Don't worry... they won't stay that way.
