Replaced
your skin replaces itself about every 30 days, everything else is replaced in cycles that take somewhat longer than that
Replaced, I believe.
The skin protects against infection by shedding on average every 35 days and in doing so, also sheds bacteria. The skin also secretes chemicals that can destroy harmful bacteria.
every 28 days
The skin consists of two layers, the inner and thicker dermis, and the outer and thinner epidermis. It takes about 35 days for the epidermis to replace itself. It replaces itself quicker than other parts of the body because it is exposed to the outside world and is constantly being abraded, cut, or scratched.
Yes, usually every 25-45 days.
Skin does not replace itself every 24 hours, it is replaces itself every 28 days, and for older people, it takes much longer of that to happen. However, this is only half the story, the skin is consisted of two layers, the dermis and the epidermis, the dermis is the lower skin layer, while the epidermis is the upper layer of the skin that you see when you look in the mirror. The epidermis is the one that take about 28 days to be replaced by a new layer, while the dermis takes roughly about 15 years to replace only half of it's contents. When you get a wound and your skin forms a scar, this scar is formed in the dermis layer, hence why a scar or a tattoo will stay a lifetime.
Humans shed and regrow outer skin cells about every 27 days.
The skin will slowly reform around your body (get tighter) as the skin cells die and regenerate (skin cells are dying every second of the day, but are being replaced at an even faster rate). Basically, you won't notice it, but the skin will flake off and be replaced by better fitting skin, which sounds gross but as mentioned before happens with everyone, every second of every day. Note that depending on your age, usually 50+, this may not happen, in which case a consultation with a doctor may be necessary, as the skin cells will no longer be replenishing themselves fast enough to reshape the skin.
Your skin cells will soon die and fall off and be replaced by new ones so it'll just come off naturally in a couple of days.
