Which of the following is a common symptom of psoriasis?

Psoriasis is an autoimmune condition that primarily affects the skin, causing rapid skin cell production that leads to the build-up of skin cells. This results in the formation of red patches, often covered with silvery-white scales. These patches can be itchy and sometimes painful. The characteristic appearance of red patches is a hallmark symptom of psoriasis, making it the most recognized and prevalent sign of this condition.

In contrast, thinning hair, blistering, and dry eyes are not directly associated with psoriasis. While thinning hair can occur due to various skin conditions or stress, and blistering is typically linked with conditions like dermatitis, dry eyes are often a symptom of different issues not related to skin inflammation. Understanding these distinctions helps to accurately identify psoriasis and differentiate it from other skin disorders.
