A biologic is a drug made from living organisms or parts of living organisms designed to target a specific part of the immune system. These targeted treatments are one of the newer types of treatments available for skin conditions and can often be very effective at reducing and managing symptoms. They are approved for use in Canada for several skin conditions, including psoriasis, atopic dermatitis, hidradenitis suppurativa, and pemphigus vulgaris.
