Psoriasis treatment Biologics Most medicines are created by combining chemicals. In contrast, "biologics" are made from human or animal proteins. Biologics have been in use for more than 100 years. Vaccines and insulin are considered biologics because they are derived from living sources. Only recently, however, have biologics that are specifically targeted toward psoriasis and psoriatic arthritis begun to emerge as potentially promising new treatment options.
