It is a chronic inflammatory skin condition that occurs when the rate of natural renewal of skin cells increases rapidly, resulting in dry, itchy and sometimes painful patches. It usually appears on the elbows, knuckles and scalp; However, it can appear on any part of the body.
The disease affects 8 million people in the United States and usually occurs between 15 and 25, according to the National Psoriasis Foundation. Barr tells us that we do not fully know what causes it, but it is related to the immune system, genetics and environmental factors.
"It is believed to be related to a problem of the immune system with T cells, specifically T regulatory cells, as well as other white blood cells, called neutrophils. While T cells normally travel through the body to defend against foreign substances, such as viruses or bacteria, if you have psoriasis, the T cells attack healthy skin cells to heal a wound or fight an infection, "says Barr. This triggers increased production of healthy cells, resulting in injuries. "Dilated blood vessels in areas affected by psoriasis also create heat and redness," she says.
That is why it is vital to address inflammation in your treatment, as noted above.
