Ultraviolet light emitted by the sun has the most diverse effects on human skin, which are positive, such as vitamin D3 negative, such as loss of fluid and elasticity, redness, spots and, in the most serious cases, skin cancer (25 per cent of cancers in Brazil, according to INC).

To this end, some experts and the World Health Organization have pointed out that the use of sunscreen is ongoing. However, prolonged exposure can lead to chemical degradation and/or sunscreen penetration into the deepest layers of the skin, reducing their protective effect and possibly inducing the production of toxic species.

The invention provides a formula for increasing the light stability and the light protection ability of rutin and sunscreen while increasing the light protection ability of the product by using the nano-encapsulation technology. The innovation is to promote RUV protection by producing solid lipid nanoparticles (NLS) of products added with antioxidant active substances and ROS scavengers. They greatly increase the retention time of substances that are locally applied to the skin.
