Psoriasis: Causes, Symptoms, and Affected Areas
Psoriasis is a chronic autoimmune skin condition that accelerates the life cycle of skin cells, causing them to build up rapidly on the surface of the skin. This buildup results in thick, red, scaly patches that may itch, burn, or crack. Psoriasis is not contagious and can vary in severity from small localized spots to full-body involvement.
The exact cause of psoriasis is unknown, but it’s understood to involve a combination of genetic predisposition and immune system dysfunction, where the immune system mistakenly attacks healthy skin cells. Triggers include stress, infections, certain medications, alcohol consumption, injuries to the skin, and cold weather.
Symptoms include raised, inflamed red patches covered with silvery-white scales, dry and cracked skin, itching or soreness, and nail changes (such as pitting or separation from the nail bed). In more severe cases, it may also involve joint pain, known as psoriatic arthritis.
Psoriasis commonly affects the scalp, elbows, knees, lower back, and nails, but it can appear anywhere on the body. Flare-ups often occur in cycles, with periods of remission in between.

Treatment Options
Over-the-Counter Products
Mild psoriasis may be managed with moisturizers, coal tar products, or salicylic acid shampoos and creams that help reduce scaling and dryness.
Prescription Topical Medications
Stronger topical treatments include corticosteroids, vitamin D analogs (like calcipotriene), retinoids, and calcineurin inhibitors for sensitive areas.
Oral Prescription Medications
For moderate to severe cases, oral systemic treatments like methotrexate, cyclosporine, or acitretin may be used to suppress the immune response and control symptoms.
Advanced Therapies
Biologic therapies (e.g., adalimumab, ustekinumab, secukinumab) target specific parts of the immune system and are effective for resistant psoriasis. Other advanced options include phototherapy (UVB or PUVA), and excimer laser treatments for localized plaques.
