What type of skin condition is psoriasis?

Psoriasis is classified as a chronic autoimmune condition, where the immune system mistakenly attacks healthy skin cells, leading to rapid skin cell production. This results in the characteristic thick, red patches covered with silvery-white scales. Unlike temporary allergic reactions, which may resolve on their own, psoriasis persists over time and often requires ongoing management.

The autoimmune aspect means that it is not caused by infections, such as those caused by bacteria or fungi. Thus, psoriasis is distinct from fungal and bacterial skin infections, which are primarily caused by external pathogens rather than the body's immune processes. Understanding psoriasis as an autoimmune disorder underscores the importance of comprehensive treatment approaches, which may include topical treatments, light therapy, and systemic medications, to manage the condition effectively.
