Vitamin A Palmitate
Vitamin A palmitate is rated 2 to 3 on our list, a range whose top puts it in the moderate band, and the number is traced: Fulton 1989 graded it 1 to 3, varying with the supplier.
Like every rating here, it is for the raw ingredient tested alone, and a label does not print how much of it a product holds.
Is vitamin A palmitate comedogenic?

What a 2–3 means in practice
Three is the middle of the scale. Fulton 1989 counted 2 to 3 as borderline in the rabbit-ear test: some plugging of the follicles, short of a clear positive. Whether it matters depends on how high it sits on the label and whether the product stays on your skin.
Two things change what this number is worth. Ingredients are listed in descending order of concentration, so vitamin a palmitate near the top of a label matters far more than vitamin a palmitate at the bottom. And the rating describes the raw ingredient on its own. A 2006 review in the Journal of the American Academy of Dermatology found that a rating for a single ingredient does not reliably predict how a finished formula behaves on human skin. The full story of the scale is here.

|---|---|---|
| Fulton 1989 | Grade 1 to 3, varying with the supplier | Tested as Vitamin A palmitate |
Our list's figure is within what these papers report.
Fungal acne
Vitamin A Palmitate matches rule 2, ester of a C12 to C24 fatty acid , on the fungal acne checker. An ester of palmitic acid, C16. The rule comes from lab studies of what Malassezia yeast can feed on, and it is not a verdict on any product.
