Solar radiation is a consolidated environmental risk factor in the development of non-melanoma skin cancer and is responsible for sunburn and skin aging. By consequence, the use of sunscreen products is considered the best approach for skin protection. Today, sunscreen products are based on conventional formulations, such as creams, milks or gels, which do not protect chemical ultraviolet filters from photodegradation and allow their systemic absorption. In this article, innovative systems, namely clays, cyclodextrins, polymer and lipid microparticles, are discussed as potential sunscreen carriers to be embedded in the aforementioned formulations. Their capability to improve sunscreen performances, to reduce their potential toxicity issues and to overcome formulation problems are examined also.

Abstract
Solar radiation is a consolidated environmental risk factor in the development of non-melanoma skin cancer and is responsible for sunburn and skin aging. By consequence, the use of sunscreen products is considered the best approach for skin protection. Today, sunscreen products are based on conventional formulations, such as creams, milks or gels, which do not protect chemical ultraviolet filters from photodegradation and allow their systemic absorption. In this article, innovative systems, namely clays, cyclodextrins, polymer and lipid microparticles, are discussed as potential sunscreen carriers to be embedded in the aforementioned formulations. Their capability to improve sunscreen performances, to reduce their potential toxicity issues and to overcome formulation problems are examined also.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
