Final answer:
The skin disease characterized by red patches and white-silver scales, usually found on certain areas of the body like the scalp and knees, is called psoriasis. It's a chronic condition caused by rapid cell turnover.
Step-by-step explanation:
The skin disease characterized by red patches covered with white-silver scales, typically found on the scalp, elbows, knees, chest, and lower back, is known as psoriasis.
Psoriasis is a chronic condition that causes itchy or sore patches of thick, red skin with silvery scales. Your skin cells grow deep in your skin and slowly rise to the surface. This process is called cell turnover, and it takes about a month. In people with psoriasis, it can happen in just a few days because the cells rise too fast and pile up on the surface.
While psoriasis is generally thought to be a genetic disease that is triggered by environmental factors, there are several different types of psoriasis. This includes plaque psoriasis, inverse psoriasis, and pustular psoriasis. In all kinds, the skin cells grow and multiply faster than they should, leading to buildup.
