Checking a real product?

Single-ingredient ratings are guidance, not a lab test of a finished formula — concentration and the rest of the ingredient list matter (Draelos & DiNardo, 2006). Paste the full list into the comedogenic ingredient checker to screen everything at once, or the fungal-acne checker if Malassezia is your problem.
