Skin constantly regenerates and takes approximately 27 days to regrow, while damaged skin growth can vary depending upon the nature and severity of the injury. Scraped skin can take as long as three weeks to grow back, whereas burned skin can take months for regrowth.
The outer layer of the skin is comprised of dead skin cells overlaying the epidermis, which is the topmost, living layer of skin. As skin cells die, they either flake off or are washed away with water.
Damaged skin can have healing growth stimulated through various means, such as stitches for deep or wide cuts that shorten the distance for new skin growth over the wound.
