In response, it accelerates the production of skin cells in that specific area, leading to the formation of a new plaque that mirrors the shape of the trauma. This results in heightened redness, swelling, and ultimately, more intense itching, compelling the individual to scratch again and perpetuating the cycle of damage and plaque formation.
Understanding the Psoriasis Itch-Scratch Cycle and Koebner Phenomenon
The Itch-Scratch Cycle: Scratching provides temporary relief but releases more inflammatory chemicals, leading to thicker plaques and more itching. Psoriasis is fundamentally an autoimmune disorder, meaning the root of the issue originates from within the immune system, not from external contact or minor skin trauma.
Why Scratching Creates a Vicious Cycle Scratching psoriasis lesions creates a distinct cycle that worsens symptoms rather than providing relief. Furthermore, the inflammation caused by the trauma sends a signal to the immune system, increasing blood flow and immune cell activity in the area.

However, if a new patch appears precisely where the skin was scratched or injured shortly before, the likelihood of the Koebner phenomenon being the cause is significantly increased. This is not the disease spreading through the bloodstream or air, but rather a localized reaction where the immune system is already primed to react.
