I would like to know if olive oil clog pores, has its own natural sun block and if kitchen grade is okay to use on your skin?
Unfiltered oil has microscopic particles of olive which tend to add flavor and nutrients. These particles are not large enough to "clog pores." Filtering extends shelf life. Cheap kitchen brands of olive oil are often the most heavily filtered and would be fine but extra virgin has more antioxidants so would be preferable.
