The sun protection factor of a sunscreen is a laboratory measure of the effectiveness of sunscreen - the higher the SPF, the more protection a sunscreen offers against UV-B (the ultraviolet radiation that causes sunburn). Biodegradable simply means to be consumed by microorganisms and return to compounds found in nature. Natural sun screen is used from ingredients forum in the earth such as plants.
