The science behind ILUMYA™

ILUMYA™ is a prescription medicine used to treat adults with moderate-to-severe plaque psoriasis who may benefit from taking injections, pills (systemic therapy), or treatment using ultraviolet or UV light (phototherapy).

ILUMYA™ is a biologic, which is a type of treatment for moderate-to-severe plaque psoriasis that may help people who haven’t been able to get their psoriasis symptoms under control—like plaques, redness, and flakes.


  • Are made using natural, living sources, such as human, plant, or animal cells
  • Target a specific part of the immune system rather than all of it
  • Block the molecules that make plaque psoriasis worse

However, ILUMYA™ is a different type of biologic medicine

ILUMYA™ works differently than most other biologics. It blocks the IL-23 molecule to help reduce the redness, flaking, and plaque thickness you see on your skin.
