i use a hydrocortisone oinment which has mineral oil and petrolatum as a base. i been using it for over 2 yrs on my face it seriously clogged my pores ALOT! but it has its good and bad. im now going to switch to jojoba and emu oil to see how it is. but i guess if it has a small amount of mineral oil in a product it should be fine. if used right it wouldnt clog your pores.
