What a 2/5 rating means
On the comedogenic scale, a 2 is still within the non-comedogenic range that dermatologists generally consider low-risk. That places Phytantriol in the range most people, including many with acne-prone skin, tolerate well.
This rating is disputed. Credible sources land on different numbers for Phytantriol, so we publish the range (2) 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 Phytantriol near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.

Is Phytantriol pore-clogging?
It is unlikely to be. At 2/5, Phytantriol sits in the range generally treated as non-comedogenic. Concentration still matters: an ingredient near the top of a label makes up far more of the product than one near the end. Comedogenic ratings come mostly from rabbit-ear assays and small human patch tests of the pure ingredient at high concentration, so they are a screening guide, not a prediction for your skin or a medical claim.
