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 30 squarely in the judgement-call zone, where your skin type and the product's formula decide the outcome.
This rating is disputed. Credible sources land on different numbers for D&C Red 30, so we publish the range (3) rather than a false single figure. When sources disagree this openly, your own experience carries real weight.
One thing the number cannot tell you is concentration. Ingredients are listed in descending order, so D&C Red 30 near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.

It can be for some people. At 3/5, D&C Red 30 is in the moderate band. How much it matters depends on concentration: near the top of an ingredient list it is a bigger factor than near the end.
