What is psoriasis?
Psoriasis is a non-infectious, inflammatory skin disease that affects 1-3% of the population. It is characterized by the presence of erythematous-papular foci covered with scales. The multifactorial pathogenesis, chronic nature of the lesions and significant resistance to treatment result in difficulties in therapeutic management and unsatisfactory treatment effects. The main goal of psoriasis therapy is to inhibit inflammation and normalize abnormal keratosis. As a result of abnormal keratosis, scales are formed on the surface of psoriasis outbreaks.
