What prompts the rapid skin cell growth in Psoriasis?

The rapid skin cell growth in psoriasis is primarily prompted by faulty signals in the immune system. In psoriasis, the immune system mistakenly attacks healthy skin cells, leading to an overproduction of skin cells in a shorter amount of time. This accelerated turnover causes the characteristic red, scaly patches associated with the condition.

While environmental factors and genetic predisposition can play roles in the onset and severity of psoriasis, they do not directly cause the rapid cell turnover. Environmental factors may act as triggers, and genetic predisposition indicates a susceptibility, but the underlying mechanism driving the rapid growth of skin cells is rooted in immune system dysfunction. Thus, it is this miscommunication and dysfunction within the immune system that fundamentally leads to the characteristics of psoriasis.
