What is the defining feature of Psoriasis?

The defining feature of psoriasis is the development of scaly patches on the skin. Psoriasis is a chronic autoimmune condition that causes accelerated skin cell production, leading to the formation of thick, silvery-white scales that can appear on various parts of the body, including the elbows, knees, scalp, and lower back. These scaly patches are often surrounded by red, inflamed skin.

While other skin conditions can involve redness and itching, the hallmark of psoriasis is specifically the accumulation of skin cells resulting in the characteristic scales. This disordered skin renewal process is what differentiates psoriasis from conditions that may present with other symptoms, such as blisters or infections. Understanding this key aspect of psoriasis is essential for identifying and managing the condition effectively in a beauty therapy context.
