skinsafecheck Ingredient Checker

Comedogenic ratings by ingredient family

The same 285 ingredients as the A to Z, sorted into what they actually are. 31 families with 3 or more members are set out below, covering 268 of the ingredients; 39 families have fewer and are folded into their entries rather than given a table of one.

Each family shows the published range across its members, which is a span of numbers other people measured. It is not an average, and it is not a verdict on the family: a rating belongs to an ingredient, and a product is a formula rather than a list. Where the published sources disagree about an ingredient, its own entry carries the range.

Families come from the composition each ingredient is published under, so they overlap. An ingredient whose composition names two will appear under both, and several pairs share most of their members. That is what the source says, and collapsing them here would be inventing a tidier taxonomy than the literature has.

Read where these numbers come from, including what the sourcing does not cover.

Where these ratings come from

  1. Kligman AM, Kwong T. “An improved rabbit ear model for assessing comedogenic substances.” British Journal of Dermatology, June 1979;100(6):699–702. (opens in a new tab) The rabbit-ear assay that produced most of the 0–5 numbers still quoted today.
  2. Fulton JE Jr, Pay SR, Fulton JE 3rd. “Comedogenicity of current therapeutic products, cosmetics, and ingredients in the rabbit ear.” Journal of the American Academy of Dermatology, January 1984;10(1):96–105. (opens in a new tab) The published ingredient-by-ingredient ratings that most comedogenic lists, including this one, trace back to.
  3. Draelos ZD, DiNardo JC. “A re-evaluation of the comedogenicity concept.” Journal of the American Academy of Dermatology, March 2006;54(3):507–512. doi:10.1016/j.jaad.2005.11.1058 (opens in a new tab) Found that animal-model results did not reliably predict what happened on human skin, and that a rating for a single ingredient does not tell you how a finished product will behave.
  4. U.S. Food and Drug Administration, “Cosmetics Labeling Claims”. (opens in a new tab) States that the FDA does not keep a list of approved or accepted cosmetic claims; a label must simply be truthful and not misleading. There is no FDA definition of “non-comedogenic” for a brand to meet.
