👉 Psalidister is a type of psoriasis that typically affects the skin in a dry, scaly, and itchy way. It can be caused by various factors such as environmental factors like pollution or exposure to certain chemicals, stress, and infections. Psalidisters are also often associated with psoriasis flare-ups, but they do not always cause them. Treatment options for psalidister may include topical treatments, oral medications, and sometimes even surgery if the condition is severe.
