What is Psoriasis?

Psoriasis is an autoimmune disease that causes inflammation in the body. There may be visible signs of the inflammation such as raised plaques (plaques may look different for different skin types) and scales on the skin. The most common form of the disease, plaque psoriasis, appears as raised, red patches covered with an accumulation of white dead skin cells. Psoriasis is not contagious.

Understanding Psoriasis

Psoriasis occurs due to the overactive immune system that speeds up skin cell growth. Normal skin cells completely grow and shed in a month. With psoriasis, skin cells do this in only three or four days. Instead of shedding, the skin cells pile up on the surface of the skin. Some people report that psoriasis plaques itch, burn and sting. Plaques and scales may appear on any part of the body, although they are commonly found on the elbows, knees, and scalp.

Inflammation caused by psoriasis can impact other organs and tissues in the body. People with psoriasis may also experience other health conditions. One in three people with psoriasis may also develop psoriatic arthritis.

Symptoms often start between ages 15 and 25, but can start at any age. Men, women, and children of all skin colors can get psoriasis.

Possible Psoriasis Causes and Triggers

The most common form of the disease, plaque psoriasis, appears as raised, red patches covered with an accumulation of white dead skin cells. Psoriasis is not contagious.


Stress is one of the most common psoriasis triggers. At the same time, a psoriasis flare can cause stress. This may seem like an endless loop. However, relaxation techniques and stress management may help prevent stress from impacting psoriasis.


Skin Injury

Psoriasis can appear in areas of the skin that have been injured or harmed. This is a result of the Koebner phenomenon, which states scratches, sunburns, bug bites and vaccinations can all trigger a psoriasis flare.


Anything that can affect the immune system can trigger psoriasis. That is why you may experience a flare following an ear infection, bronchitis, tonsillitis or a respiratory infection.


The weather may trigger a flare. Cold weather can often cause psoriasis flares due to less sunlight and humidity, heated and drier indoor air, as well as stress and illness. Warm weather can often improve psoriasis because of natural sunlight and higher humidity.

Other Possible Triggers

Although it is less common, some people with psoriasis suspect that allergies, certain foods, alcohol or environmental factors trigger their psoriasis. A great way to learn about your unique set of triggers is to track them over time.

What Can A Dermatologist Do?

Psoriasis is often a lifelong condition. Psoriasis and psoriatic arthritis treatments aren’t one-size-fits-all, and that’s a good thing. It means that you can work with your dermatologist to find the right psoriasis treatment — or combination of psoriasis treatments — for you that reduces or eliminates your symptoms.

To help their patients live well with psoriasis, dermatologists recommend the following:

  • Use psoriasis friendly skin care
  • Find and avoid your psoriasis triggers
  • Treat the psoriasis as needed
  • Tell your dermatologist about symptoms, even if they seem unrelated

Within, you’ll find dermatologists’ insight that can help you diminish psoriasis, reduce flare-ups, and feel better.

Psoriasis Can Affect More Than Your Skin

Studies show that psoriasis increases the risk of developing other medical conditions. Be sure to tell your dermatologist if you have any of these signs or symptoms.
