Timespan of the skin cells

Consequently, too many skin cells accumulate on the skin’s outer layer. Therefore, this is why some types of psoriasis cause the skin to have a reddish, scaly appearance. It normally takes about few weeks for new skin cells to form, however, for people with psoriasis, skin cells form within the timespan of just several days. As a result, the body doesn’t shed the excess cells and psoriasis lesions occur.
