What a 3 means in practice

Three is the tipping point on this scale. It does not usually cause an immediate spot, but it is where a slow build-up inside the pore starts to show up over weeks in a leave-on product.

Two things change what this number is worth. Ingredients are listed in descending order of concentration, so ethoxylated lanolin near the top of a label matters far more than ethoxylated lanolin 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.
