Can skin layers rejuvenate themselves?
They do when the skin is young. At younger ages, our skin possesses a higher number and density of collagen fibers, which keep the skin tight and firm-looking. However as we grow old, their number decreases and the skin can no longer use them as before - and thus becomes wrinkled and sagging. However, there are many anti aging skin products today that promote skin rejuvenation by stimulating collagen growth. So in a way, it's done by the skin too, except that the skin needs ome outside help to start the process.

What is the functional relationship between melanin melanocytes and tanning of the skin?
Melanocytes make the pigment melanin in response to sunlight. The pigment is protective. The pigment in the skin appears as "a tan". More sun = more tan. Sunlight can cause cancer of the skin. A person with a darker skin is more protected. People who live in areas with a lot of sun have adapted to that sun by having darker skin. Of course, when they move to other areas, they pass on the gene for darker skin even if it isn't necessary.
My understanding of this process is that a snake will shed it's skin when it grows to the point the skin stretches beyond it's limits and is replaced by a new skin that accompanies the new size of the reptile. The frequency of the shedding process is directly linked to the feeding amount done by the snakes owner. Snakes are typically feed every 7 to 10 days but can be feed more to provide "power feeding" and therefore causing the snake to grow more rapidly. Keeping the snakes enclosure humid will help the skinning process as will placing a rough rock or item within the enclosure for the reptile to rub against. Usually the first indication of a snake that is about to shed is what is called eye caps appearing. The eyes will get a dull film look to them and does hamper the snakes vision. Snakes are more apt to strike an owner (on purpose or even accidently) during the eye cap phase due to his inability to properly see and it's nervousness resulting there of.
It varies ! Young snakes will shed more frequently than older ones, as they do most of their growing in the first five years. As they get older, they don't grow as fast so they don't need to shed as often.
