Psoriasis is an autoimmune disease that causes the appearance of raised, scaly, and red patches on the skin. Typically seen on the elbows, knees, and scalp, this non-contagious condition affects people of all ages, races, and genders. Clients with psoriasis may experience itching, burning, and stinging, along with a variety of emotional responses, including depression and embarrassment. Despite the fact that psoriasis is incurable, skin care professionals can help clients experience relief. Kristina Valiani says, "Psoriasis is a medical condition that occurs when skin cells grow too quickly. Faulty signals in the immune system cause new skin cells to form in days rather than weeks. The body does not shed these excess skin cells, so the cells pile up on the surface of the skin and cause lesions to form."Want to read more?
