Final answer:
Psoriasis is an autoimmune disease that causes the skin cells to multiply quickly, resulting in thick scales and red patches. It is not caused by the skin cells attacking and killing each other.
Step-by-step explanation:
Psoriasis is a chronic autoimmune disease that affects the skin. It causes the skin cells to multiply quickly, leading to the formation of thick, silvery scales and itchy, dry, and red patches.
The immune system mistakenly attacks the healthy skin cells, leading to inflammation. The exact cause of psoriasis is unknown, but it is believed to involve a combination of genetic, immune system, and environmental factors. It is not caused by skin cells attacking and killing each other.
Treatments for psoriasis include topical creams, oral medications, phototherapy, and biologic drugs. These treatments help to slow down cell growth and reduce inflammation, relieving symptoms and improving the appearance of the skin.
