Tocopherol (Vitamin E)
No published rating — we don't invent numbers.
Circulated lists grade plain vitamin E 2–3, but none of those numbers traces to a named publication, so this site does not display one. The common ester form in products, tocopheryl acetate, is graded 0 in the original Fulton 1989 table.
Every rating on this site traces to published comedogenicity literature. When no number does, the honest answer is the one above.
