How to Treat Psoriasis

Psoriasis is a long-lasting skin condition that causes thick, scaly patches. While there is no cure, many treatments can help control symptoms and clear your skin. The right treatment depends on how severe your psoriasis is and which type you have.

Topical Treatments

Creams and ointments applied to the skin are usually the first treatment doctors try. Topical corticosteroids reduce inflammation and slow skin cell growth. They come in different strengths for different body areas. Other topical options include vitamin D creams, retinoids, and coal tar products. These work best for mild to moderate psoriasis. You may see improvement in as little as one week, but full results take several weeks.

Light Therapy

Light therapy, also called phototherapy, uses ultraviolet light to slow skin cell growth. Narrowband UVB therapy is the most common type and works for about 80% of patients with thin plaques. Treatment requires going to a clinic two to three times per week. Some people benefit from brief daily sun exposure of about 10 minutes. Doctors may also use excimer lasers to target specific patches.

Oral Medications

For moderate to severe psoriasis, doctors may prescribe pills that work throughout your body. Methotrexate slows skin cell production and reduces inflammation. Apremilast targets specific enzymes in your immune system. A newer pill called deucravacitinib was approved recently and offers another option. These medications require regular blood tests to check for side effects.

Biologic Medications

Biologics are injected medications that target specific parts of your immune system. They are very effective for severe psoriasis and psoriatic arthritis. Common biologics include adalimumab, secukinumab, and newer options like bimekizumab. Many people see clearer skin within a few months. Biosimilars, which are affordable versions of these drugs, are now available.

Lifestyle Changes That Help

Along with medical treatment, lifestyle changes can improve your symptoms. Keep your skin moisturized to reduce dryness and scaling. Avoid triggers like stress, smoking, and alcohol. Losing weight if needed may help treatments work better. Talk to your dermatologist about which treatment plan is right for you.
