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 Isocetyl Alcohol 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 Isocetyl Alcohol, 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 Isocetyl Alcohol near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.
