Psoriasis is a chronic autoimmune condition in which the immune system speeds up skin cell turnover dramatically, causing cells to build up on the surface faster than the body can shed them. That buildup shows up as the raised, scaly patches most people associate with the condition, though psoriasis can also affect the scalp, nails, and joints (in the case of psoriatic arthritis). It tends to run in cycles of flares and remission, and triggers — stress, certain infections, weather, specific medications — vary quite a bit from person to person.
When professional advice matters
See a dermatologist for new or worsening skin patches, joint pain or swelling that could indicate psoriatic arthritis, or flares that aren’t responding to your current routine. A formal diagnosis matters because psoriasis can resemble other skin conditions, and treatment approaches differ.
Everyday wellness questions
Tracking flare triggers — stress, weather changes, skincare products, illness — over time can reveal patterns that are hard to spot in the moment. Photos of affected areas over weeks or months are also genuinely useful for a dermatologist assessing progression.

Common questions
No — it’s an autoimmune condition, not an infection, and it cannot be spread through skin contact.
Roughly a third of people with psoriasis go on to develop psoriatic arthritis, where the same immune process that affects the skin also affects the joints. New joint pain or stiffness in someone with psoriasis is worth mentioning to a doctor.
Some people report that certain foods worsen or improve flares, and there’s ongoing research into inflammation and diet generally, though responses vary a lot by individual and there’s no single diet proven to work for everyone.
