Plaque Psoriasis: What It Is and How to Manage It
Plaque psoriasis is the most common form of psoriasis. You’ll usually see red, raised patches with silvery scales, often on elbows, knees, scalp, or lower back. It can itch, sting, or crack, and flare-ups come and go. This page collects clear, practical info to help you recognize symptoms, understand treatments, and manage everyday life.
How Doctors Diagnose and What Causes Flares
Diagnosis usually comes from a skin exam and a short medical history. No single test proves psoriasis, but your doctor may order blood tests to rule out other conditions. Causes combine genes and your immune system—your body overreacts and speeds up skin cell growth. Common triggers are stress, infections (like strep throat), certain meds, smoking, alcohol, and skin injuries. Knowing your triggers helps prevent flares.
Common Treatments
There’s no cure, but many treatments control symptoms. Topical treatments—creams and ointments—are the first line for mild to moderate plaque psoriasis. They include corticosteroids, vitamin D analogs, and coal tar. If creams don’t help, your doctor might suggest phototherapy—controlled UV light sessions that slow skin cell growth.
For moderate to severe cases, oral or injected systemic drugs help. Traditional options like methotrexate or cyclosporine suppress the immune response. In recent years, biologic drugs have changed the game by targeting specific immune molecules (like TNF, IL-17, or IL-23). Biologics can be very effective, but they need monitoring for infections and other side effects.
Ask your provider about pros and cons of each option. Treatment choice depends on how much skin is affected, symptoms, other health issues, and your lifestyle.
Practical Self-care Tips
Small daily habits make a big difference. Keep skin moisturized—look for thick emollients and apply right after bathing. Use gentle, fragrance-free soaps and lukewarm water. When itching spikes, cold compresses can help more than hot showers. If stress triggers your flares, try short relaxation practices, regular sleep, and gentle exercise.
Be careful with over-the-counter products: some can irritate. If you smoke or drink a lot, cutting back can reduce flare intensity and improve treatment response. Also, protect injured skin—cuts or sunburns may trigger new plaques.
When should you see a doctor? If lesions cover a lot of skin, are painful, or affect quality of life (sleep, work, relationships), see a dermatologist. Psoriasis can also involve joints—if you have joint pain or stiffness, ask about psoriatic arthritis.
