How to treat or cure psoriasis

Psoriasis cannot be cured at present, but it can be controlled very well. Treatment depends on how severe it is and where it is.

Step 1: see a dermatologist

A skin specialist confirms the diagnosis and checks the joints, nails and general health.

Step 2: skin care for everyone

• Moisturise at least once or twice daily, especially after bathing
• Use lukewarm water and mild soap-free cleansers
• Avoid scratching and picking, which can trigger new patches
• Protect skin from injury and sunburn, but short sensible sun exposure can help

Step 3: creams and ointments (mild to moderate disease)

• Topical steroids, used as directed and for limited periods
• Vitamin D analogues such as calcipotriol
• Coal tar, salicylic acid and calcineurin inhibitors for some sites

Step 4: light therapy

Narrowband UVB phototherapy, in a clinic, helps many people with widespread disease.

Step 5: tablets and injections (moderate to severe disease)

• Methotrexate, ciclosporin, acitretin or apremilast
• Biologic medicines that target specific immune signals, for severe disease or psoriatic arthritis
