What a 3/5 rating means
On the comedogenic scale, a 3 is the moderate midpoint: tolerated by many, a possible trigger for congestion-prone skin. That puts D&C Red 17 squarely in the judgement-call zone, where your skin type and the product's formula decide the outcome.
One thing the number cannot tell you is concentration. Ingredients are listed in descending order, so D&C Red 17 near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.
