Every Month, You Shed Your Entire Outer Layer of Skin — and Never Notice
The epidermis is constantly flaking off and renewing itself — your entire outer skin layer turns over roughly once a month.
The outermost layer of skin, the epidermis, is essentially a stack of dead, keratinized cells that are constantly flaking off and being replaced by fresh ones from below.
A full renewal cycle for this layer takes an adult roughly a month — which means the surface of your body you're touching right now physically didn't exist a few weeks ago.
A significant portion of household dust is exactly this — shed skin cells. You're literally leaving pieces of yourself on every surface you pass.
The process speeds up or slows down with age, which is one reason children's skin heals from injuries noticeably faster than older adults' skin does.
