Ingredients rated 3–5 that appear after position 15 are usually present below about 1%, so they are shown as "Low amount" and do not trigger the pore-clog alert. Ratings come from the Fulton comedogenic scale (0–5) and published Malassezia research. They are a rough guide: the concentration and the whole formula matter, and everyone's skin is different.
