A 2017 study published in the American Journal of Clinical Dermatology that involved more than 5,000 patients found that severe psoriasis strikes more men than women. But who actually gets psoriasis often comes down to genes. Psoriasis occurs when the immune system causes certain areas of your skin to produce new cells more rapidly than normal, which leads to thickening and scaling. It's not clear what makes this happen, but scientists believe that most people with psoriasis inherit one or more of certain genes that can affect the immune system in a way to make them prone to psoriasis. But it is not enough to have a genetic connection. Flare-ups often occur when certain triggers start the psoriasis process. The most common is stress. Mental stress causes the body to release chemicals that boost the inflammatory response. Scientists suspect this is the mechanism for stress-induced psoriasis flare-ups.
