Psoriasis is a common skin condition characterized by excessive skin cell development. It’s a chronic skin disease that can come and go over time. The problem usually arises in early adulthood.
If you have psoriasis, your skin cells can multiply as many as 10 times faster than a person without the condition. Your body is unable to shed old cells fast enough to make room for these new skin cells, so they begin to accumulate in stacks that look like patches of rough, scaly skin.
Most men and women with psoriasis only develop patches on a few areas of their body. In rare cases, psoriasis is widespread and covers larger areas. Your skin will go through cycles of healing before the condition worsens and patches return.
Plaque psoriasis is the most common form of the condition, but there are several other types of psoriasis that cause slightly different symptoms.
