Skin cells can multiply up to 10 times more quickly than usual when someone has the skin condition psoriasis. As a result, the skin develops into red spots that are rough and coated with white scales. In the lowest layer of skin, your body regenerates new skin cells.

Normally, the entire process takes three to four weeks.
