Detailed answer

Psoriasis is an autoimmune condition characterized by the rapid production of skin cells. While the exact cause is unknown, trauma to the skin, such as cuts, burns, or even tattoos, can trigger the development or worsening of psoriasis. This is known as the Koebner phenomenon. The trauma disrupts the skin barrier, leading to inflammation and immune system activation, which can trigger psoriatic lesions to form in the affected area. It is important to take proper care of the skin to minimize the risk of triggering or exacerbating psoriasis.
