Description
Summary:[Display omitted] Psoriasis is a chronic inflammatory non-contagious disease normally characterized by a multisystemic inflammation with reddish plaques and whitish scales with greater incidence in the knees, feet and hands, elbow, scalp, and sacral areas. The global incidence of psoriasis rounds about 2% of the population and it is established that the pathophysiology of this skin disease is quite complex and still misunderstood. Nowadays, this pathology still has no cure, however, efforts are being made to find more effective and safe treatments as well as trying to decrease the occurrence of crises and complications. Nanotechnology is increasingly becoming an innovating and promising new approach for the study of various dermatological diseases, such as psoriasis. In this case, the interest in the use of nanocarriers arises in order to decrease the side effects associated with conventional therapy, as well as improve its effectiveness. Nanotechnology allows for better solubility and better delivery of the drugs, as well as an increase in their tolerance. Besides psoriasis pathophysiology and its conventional treatments, this manuscript will also be present and discusse nanotechnological strategies for topical application that intend to increase the effectiveness of treatment, as well as its regulatory and toxicological context. Regulatory issues as well as nanotoxicological concerns and long-term safeness, both for the user and for the environment will be discussed.
