What a 0 means in practice
Zero is the bottom of the scale: not expected to block a pore at all.
Two things change what this number is worth. Ingredients are listed in descending order of concentration, so hemp seed oil near the top of a label matters far more than hemp seed oil at the bottom. And the rating describes the raw ingredient on its own. A 2006 review in the Journal of the American Academy of Dermatology found that a rating for a single ingredient does not reliably predict how a finished formula behaves on human skin. The full story of the scale is here.
