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 Camphor in the range most people, including many with acne-prone skin, tolerate well.
One thing the number cannot tell you is concentration. Ingredients are listed in descending order, so Camphor near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.

Is Camphor pore-clogging?
It is unlikely to be. At 2/5, Camphor 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.
