Depends. It takes about a month for an entire new layer of skin to grow back. Your skin has multiple layers though, so if the top layer is destroyed, it will be replaced by the second layer, and so forth.

It will take about 3 to 6 months for fingernails to regenerate or regrow completely. The growth rate will depend on the age of the person.
The neurons in the brain and else where do not normally regenerate. Skin cells do regenerate.
1 month
it has silky skin and can 'regenerate quickly:-)
how long does it take to grow a new layer of skin
The skin cells that you have when you get the tan regenerate to new ones, so obviously the new skin cells will be not tanned and the dead tanned skin comes away. This happens over a period of time, however long it takes your skin cells to regenerate over 2 weeks etc so you would keep your tan for atleast 2 weeks.why did you want a tan in the first place. wow.
Planaria can regenerate within a couple of weeks. The exact time can vary depending on factors such as the size of the planaria, the extent of the injury, and the environmental conditions. Generally, smaller injuries will heal faster.
The Skin
As unfortunate as this may sound, nerves do not heal. Nor do they regenerate. If you've suffered an injury that's caused nerve damage, that damage will not heal or regenerate.
the cheek
The tissues that regenerate well in the body include the skin, liver, bone marrow, and the inner lining of the intestine. These tissues have a high capacity for cell proliferation and replacement, allowing them to heal and regenerate after injury or damage.
