Psoriasis is a common skin condition that affects millions of people worldwide. It is a chronic condition that can occur at any age, although it typically first appears between the ages of 15 and 35. While psoriasis is relatively common, it is not necessarily “normal” in the sense that it is not a natural part of the body’s functioning. Psoriasis is believed to be caused by an overactive immune system, and while there are treatments available that can help manage the symptoms of psoriasis, there is no known cure. If you are experiencing symptoms of psoriasis, it is important to see a healthcare provider for an accurate diagnosis and treatment plan.
