Forming the most visible layer of human skin is what is known as the epidermis, which is comprised on the surface by what scientists refer to as dead stratified squamous, keratinized epithelial cells (usually referred to more simply as the epithelium).
These dead top cells flake off the body over a period of weeks, to be replaced by further cells which are constantly growing underneath and are pushed toward the surface by way of mitosis.
Yes, usually every 25-45 days.

Snakes shed because there skin does not grow with there body, as human skin grows with the body. Snakes shed more when there young and shed less when there older. Rattlesnakes grow a new layer of there rattle every time they shed, so the older the louder.
ALL snakes (and lizards) shed their skin periodically. The general rule is - the younger the reptile - the more frequently they shed. Reptile skin is regenerated all at once - not in tiny flakes like human skin. Thus they have to shed their skin in order to grow.

Humans do shed skin. When skin cells die, it falls off your body it's called Desquamation. Every hour nearly 40,000 skin cells are shed, and it takes one skin cell about a month to complete the desquamation process. In fact, person from 2009 that says humans don't shed, the dust in your home is mostly dead skin cells. Your dead skin literally falls off your body.
humans shed their skin but over a long period of time, 90% of dust inside a house is dead human skin and heir and nails
Skin is our body's fastest growing organ because we shed millions of skin cells every day, prompting new cells to rapidly replace them. This constant turnover and regeneration process helps to keep our skin healthy and functioning properly.
