Psoriasis is a chronic, recurring inflammatory skin disease, which is neither infective nor contagious. There over 100 million people affected around the world, 2.5 million in Italy.
The characteristic of psoriasis is the onset of red patches, covered by silvery-white plaques, located in specific areas such as elbows, knees and scalp. The lesions are persistent.
Psoriasis develops when the body’s immune system causes a fast growth of the epidermis, leading to the development of patches. This is caused by a genetic change – which is inherited – associated with other environmental and psychological factors.
