Osmosis video - Psoriasis

Psoriasis is an autoimmune disorder that affects the skin, which leads to the excessive proliferation of keratinocytes that don't mature correctly. It is characterized by thick, scaly, and silvery patches on the skin, known as plaques. These plaques are often itchy and painful, and they can crack and bleed. Psoriasis typically appears on the scalp, elbows, knees, and lower back, but it can also affect the nails, genitals, and mouth. Psoriasis treatment can include topical creams and ointments; immunosuppressive therapies, and UV phototherapy. For some individuals, there can be significant feelings of depression or anxiety, and a need for psychological counseling.
