Psoriasis treatment aims to reduce inflammation, clear the skin, and manage symptoms. Common options include topical treatments like corticosteroids and vitamin D analogs, which help to slow skin cell growth and reduce redness. For more severe cases, doctors may prescribe systemic medications or biologics that target specific parts of the immune system. In addition to medications, lifestyle changes can also help manage psoriasis. Maintaining a healthy diet, managing stress, and avoiding triggers such as smoking or excessive alcohol can improve symptoms. Light therapy, which involves exposure to ultraviolet light, is another effective treatment for many individuals with psoriasis.
