Psoriasis is a chronic autoimmune skin condition that causes the rapid growth of skin cells, leading to the formation of thick, red, scaly patches on the skin. The exact cause of psoriasis is not fully understood, but it is believed to be a combination of genetic and environmental factors. Psoriasis can affect any part of the body, but it most commonly appears on the elbows, knees, scalp, and lower back.
Psoriasis can also affect the skin on the face, including the eyelids, eyebrows, and hairline. In some cases, psoriasis can also infect the mucous membranes, such as the inside of the mouth and the genital area. Psoriasis can be triggered or worsened by factors such as stress, infections, certain medications, and changes in weather. Treatment options for psoriasis include topical creams, oral medications, light therapy, and biologic injections. It is important for individuals with psoriasis to work closely with a healthcare provider to develop a treatment plan that works best for their specific condition.
