How is the severity of psoriasis measured?

Symptoms and Severity

In addition to scalp, knees, elbows and torso, psoriasis can also develop on the nails, hands, feet, genitals, buttocks, and, rarely, on the face.

The severity of psoriasis is also measured by the impact psoriasis can have on a person’s quality of life. Psoriasis can have a big impact even if it involves a small percentage of BSA.
