Psoriasis

Psoriasis is a chronic skin condition caused by an overactive immune system. Symptoms include flaking, inflammation, and thick, white, silvery, or red patches of skin. Topical psoriasis treatments like sprays, foams, and shampoos, as well as more advanced gels and ointments, now treat larger or more sensitive areas. They’re safer and work better than older meds.

Some of the biggest advances have been in this type of drug. Biologics are made from living cells, and they target certain parts of the immune system that play a role in psoriasis. Doctors tend to use a step-by-step approach to treatment. They start by prescribing milder creams and phototherapy. If those don’t work, they move on to meds that affect your whole body.
