Psoriasis vulgaris explained

Plaques often have a clear edge and a dry, scaling surface. They may occur on the elbows, knees, scalp, trunk, or other areas, and their colour can look different on different skin tones. Itching is frequent, but some people mainly notice tightness, soreness, or visible scale. Psoriasis is an inflammatory condition and is not caused by poor hygiene or spread by ordinary contact. A clinician may diagnose it by examining the skin, while unusual or uncertain lesions may need further assessment.

Treatment may include moisturisers, prescription creams, light treatment, or medicines that work throughout the body, depending on the extent and impact of the condition. Apply products consistently as directed and moisturise after bathing to reduce dryness and cracking. Use lukewarm water, avoid harsh scrubbing, and do not pick scale from plaques. Tell a clinician if symptoms affect sleep, work, mood, or movement, because those effects help determine an appropriate treatment plan.

Arrange medical review for a new persistent rash, rapidly worsening plaques, painful cracking, or symptoms that do not settle with your current plan. Seek prompt care for widespread redness with feeling unwell, pus, fever, or severe tenderness. Painful swollen joints, heel pain, or prolonged stiffness also need timely discussion, since psoriasis may affect joints as well as skin.

Ask whether your patches fit psoriasis vulgaris, which treatment is suitable for each body site, how long to try it, and how to manage flares. Discuss scalp care, nail changes, joint symptoms, and which warning signs should lead you to seek earlier review.
