Psoriasis

Understanding Psoriasis

Psoriasis is a chronic autoimmune condition that speeds up the skin cell cycle and leads to thick, red, scaly plaques that may itch, sting, or feel tight. Plaques can appear anywhere, most often on the elbows, knees, scalp, and lower back, and may also affect the nails. The condition typically cycles through flares and periods of remission, which can affect comfort, confidence, and daily life.

Psoriasis can be associated with other health concerns, including psoriatic arthritis, cardiovascular disease, and metabolic conditions. Not everyone with psoriasis will experience these issues, but they are important to consider during evaluation and long term management.

Psoriasis results from an immune system misfire that signals the skin to produce cells more quickly than normal. Genetics and environment both play a role. Common triggers include skin injury, infections, certain medications, cold or dry weather, stress, smoking, and heavy alcohol use. Identifying and reducing personal triggers helps limit flares and supports better control.

Plaque psoriasis is the most common form. It presents as raised, red plaques with a silvery scale on areas such as the knees, elbows, lower back, and scalp. Plaques can crack, bleed, burn, or itch and may cause nail pitting or separation.

Treatment is individualized based on severity, body areas involved, type of psoriasis, and medical history. Plans often combine therapies to improve control while protecting the skin barrier.

Topical therapies

  • Corticosteroids to reduce inflammation and itching

  • Vitamin D analogs to slow skin cell growth

  • Topical retinoids to normalize turnover

  • Calcineurin inhibitors for sensitive areas such as eyelids or skin folds

  • Keratolytics like salicylic acid to lift scale and enhance penetration of other medicines

Phototherapy

  • Narrowband or broadband UVB to slow abnormal growth

  • PUVA, which combines a light sensitizer with UVA under supervision

Systemic and advanced therapies

  • Traditional systemic medicines such as methotrexate or cyclosporine for moderate to severe disease

  • Oral agents such as apremilast to reduce inflammatory signaling

  • Biologic medicines that target specific immune pathways and have been highly effective for many patients

Lifestyle and supportive care

  • Regular use of emollients and ointments to reduce dryness and scale

  • Stress management and sleep support to limit flare frequency

  • Thoughtful diet and weight management as part of overall health

  • Trigger awareness, gentle skin care, and sun protection
