Comedogenic Oils: How Common Oils Rank on the 0 to 5 Scale

Oils are some of the most confusing ingredients in skincare. One blog calls coconut oil a miracle moisturizer while another blames it for every breakout you have ever had. Jojoba oil sits on “non-comedogenic” lists everywhere, yet its actual rating is a 2 out of 5. No wonder reading an oil’s label feels like guesswork.

This hub is the site’s central reference for oil ingredients and pore clogging: common skincare oils rated on the standard 0 to 5 comedogenic scale, plain-language guidance on what each rating band means for acne-prone skin, and links to in-depth guides for the most searched oils. Ratings follow the site’s own pore-clogging ingredients list so they stay consistent across every page. Silicones such as dimethicone are not oils and are not listed here; they get their own hub.

How the 0 to 5 Rating Scale Works

The comedogenic scale rates how likely a single ingredient is to clog pores, from 0 (will not clog pores) to 5 (highly likely to clog pores). Ratings of 0 to 1 are generally considered low risk, 2 is moderately low, 3 is moderate, and 4 to 5 carry a high risk for acne-prone skin. Our full comedogenic scale guide explains where these numbers come from.

Two caveats matter before you read the table. First, ratings describe the pure ingredient at high concentration, not your finished product: a rating-2 oil near the end of a well-formulated moisturizer behaves very differently from the same oil applied pure. Second, skin responses vary. Treat ratings as a risk signal for comparing ingredients, not a verdict on any single product. Running the full ingredient list through the free Pore-Clogging Ingredient Checker is always more informative than judging one oil alone.

The Complete Comedogenic Oils Rating Table

Every oil below shows its commonly published comedogenic rating and a short note for acne-prone skin; oil names link to the full guide where one exists. Squalane is grouped with face oils here, though chemically it is a hydrogenated hydrocarbon, not a true oil.

What Each Rating Band Means for Your Skin

Rated 0 to 1: the safer bets. Hemp seed, safflower, sunflower, argan, squalane, castor, and rosehip oils sit here. If your skin clogs easily, start here; in common usage, “non-comedogenic” usually means a 0 or 1.

Rated 2: the middle ground. Jojoba, olive, avocado, sweet almond, and hazelnut oils land here. Many acne-prone people use them without trouble, especially inside formulated products rather than pure, but patch testing is sensible and oily skin types should keep amounts small.

Rated 3 to 5: use with caution. Soybean, corn, and cottonseed oils at 3, coconut oil at 4, and wheat germ oil at 5 are the most likely to cause problems on acne-prone faces. They are simply better suited to body care, hair, or very dry, non-reactive skin. Coconut oil in particular is one of the most common breakout triggers in “natural” skincare.

How to Use This Hub When You Shop

A rating table is most useful when you know how to apply it. Work through this checklist whenever an oil shows up in a product you are considering:

1. Check the position in the ingredient list. An oil in the top five matters far more than the same oil near the end.
2. Consider the whole formula. A rating-2 oil in a light serum differs from a thick balm built on rating-4 oils. See how to tell if a product is clogging your pores for the full method.
3. Remember fungal acne is a separate check. Most plant oils can feed Malassezia yeast, the organism behind fungal acne, even when rated low. Squalane is the common exception. If your bumps are small, uniform, and itchy, read what fungal acne is first.
4. Do not forget hair products. Oils in hair oils, pomades, and conditioners migrate to the forehead and hairline. See can hair products cause acne if breakouts cluster there.
5. Patch test new oils. Apply a small amount to the jawline for several days before going full face, and introduce only one new oil at a time.

When you want a moisturizer built around low-rated oils rather than a pure oil, our non-comedogenic moisturizer guide compares finished products instead of single ingredients.
