Full Answer

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.

    How long does it take the liver to regenerate?

    A:

    The liver can completely repair damaged areas within 30 days, according to the University of Iowa. The liver is the only organ that can replace damaged tissue with new cells instead of scar tissue. However, when scar tissue does develop in the liver from cirrhosis, for instance, it isn't replaced with new cells. An overdose of Tylenol can kill 50 to 60 percent of liver cells in about three days.
