How do you stop psoriasis from spreading?

Psoriasis Revolution – it is an abnormal body reaction on external irritants whereby in some parts of the body the upper layer of the skin dies faster than usual. If a normal cycle of division and maturation of the skin cells happens in 3-4 weeks, then during psoriasis this process is occurring within 4-5 days.
