I find that the skin around my big toes has become very wrinkled in the past one year. it was perfect before that, as is the rest of my skin on my face and body. is this to do with keratin loss? can it happen overnight like this? even my palms, which were very soft and moist about 10 years ago, overnight lost their softness and moisture and became hard. is this keratin loss too? and is there a remedy?

Two related answers (copied from www.newscientist.com) are:
The tips of fingers and toes are covered by a tough, thick layer of skin which, when soaked for a prolonged period, absorbs water and expands. However, there is no room for this expansion on fingers and toes, so the skin buckles. To those answers I would add that the friction skin on the palms and soles of the feet is bacically the same as the finger and toe tips mentioned.
Your whole body does not become crinkled as the skin has a layer of waterproof keratin on the surface, preventing both water loss and uptake. On the hands and feet, especially at the toes and fingers, this layer of keratin is continually worn away by friction. Water can then penetrate these cells by osmosis and cause them to become turgid.
With enough information about environmental conditions, and with fine quality contemporary images (taken at the time of recovery from the water, for example) a pathologist may be able to make some determination about length of time submerged. Other body factors (including putrefaction, insect infestation on any area exposed to the air, evidence of fish or crab nibbling, etc.) may provide even more clues than wrinkled friction ridge skin.

I've always wondered why your fingers go all wrinkly in the bath - can someone explain it to me? Also, can you tell how long a body has been immersed in water by how many wrinkles (or the size of, or anything else) it has?
