Psoriasis rash: how it can look and feel

Psoriasis commonly forms plaques where skin cells build up faster than they shed. The surface may feel thick or rough, and colour can range from pink or red to darker or violet tones depending on skin tone. Common sites include the scalp, elbows, knees, lower back, and body folds, although other areas can be involved. Itch, burning, tightness, cracking, or tenderness may accompany the rash. A rash can have several causes, so a clinician considers its distribution, scale, timing, medicines, and exposures before confirming the diagnosis.

Use prescribed creams, ointments, or other treatments according to the directions and apply them to the rash rather than rubbing aggressively. Moisturise after bathing with a fragrance-free product. Keep nails short, avoid scratching, and protect the area from friction, sunburn, and harsh cleansers. Record possible flare triggers such as illness, stress, skin injury, or a new product, while remembering that a trigger is not always identifiable. Do not stop a prescribed medicine without discussing it.

Arrange care if the rash is new, spreading, painful, or interfering with sleep or daily activities. Seek urgent help for widespread redness, extensive peeling, pus-filled areas, fever, chills, facial swelling, eye symptoms, or a rash after starting a medicine. New joint swelling or stiffness should be reported even if the skin symptoms seem mild.
