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.

IngredientCommon comedogenic ratingNotes for acne-prone skin
Argan Oil0/5Commonly rated 0; rich in vitamin E and widely considered non-comedogenic.
Hemp Seed Oil0/5One of the lowest-rated oils; light, dry feel that suits oily skin.

Safflower Oil0/5Light texture; commonly fine for oily and combination skin.
Sunflower Oil0/5Light and widely used in non-comedogenic formulas. Read the full guide.
Squalane0-1/5A hydrogenated hydrocarbon, not a true oil; stable, light, and well tolerated.
Black Currant Seed Oil1/5Light; rarely an issue at the low concentrations used in formulas.
Camellia Oil1/5Lightweight traditional face oil; low risk for most skin types.
Castor Oil1/5Thick; most often used diluted in cleansing oil blends.
Grapeseed Oil1/5Light, dry feeling linoleic rich oil. Buy small fresh bottles, it can go rancid. Read the full guide.
Pomegranate Seed Oil1/5Light; fine for most skin types in small amounts.
Pumpkin Seed Oil1/5Light; low risk in typical cosmetic formulas.
Rosehip Seed Oil1/5Popular for marks and texture; oxidizes quickly, so buy small fresh bottles. Read the full guide.
Sea Buckthorn Oil1/5Potent color; used in drops, not as a base oil.
Watermelon Seed Oil1/5Very light; a common pick for oily skin types.
Almond Oil (Sweet)2/5Moderate; better for dry, non-reactive skin. Read the full guide.
Apricot Kernel Oil2/5Similar profile to sweet almond; patch test before facial use.
Avocado Oil2/5Rich; suits dry skin more than oily, breakout-prone skin.
Borage Oil2/5Rich; use sparingly on the face.
Evening Primrose Oil2/5Moderate; keep amounts small on acne-prone skin.
Hazelnut Oil2/5Light for a rating-2 oil; many oily types tolerate it.
Jojoba Oil2/5A liquid wax ester that mimics skin’s own sebum; widely tolerated.
Olive Oil2/5Heavy; fine for body use, cautious use on the face.
Peanut Oil2/5Moderate; also a concern for nut allergies.
Sandalwood Seed Oil2/5Moderate; uncommon in mainstream formulas.
Sesame Oil2/5Moderate; popular in body massage oils.
Tamanu Oil2/5Thick and green; test carefully on acne-prone skin.
Corn Oil3/5Moderate risk; skip on the face if you break out easily.
Cotton Seed Oil3/5Moderate risk; check its position in the ingredient list.
Karanja Oil3/5Moderate risk; uncommon in facial formulas.

Coconut Oil (Unrefined)4/5High risk on the face; body and hair use for most acne-prone people.
Wheat Germ Oil5/5Highest rating; avoid on acne-prone facial skin.

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.

Frequently Asked Questions

What is the most comedogenic oil?
Wheat germ oil, rated 5 out of 5, tops the published scale, followed by coconut oil at 4. A rating describes the pure ingredient at high concentration, though: a small amount of a higher-rated oil low in a good formula is less risky than a large amount applied pure.
Which oils are considered non-comedogenic?
In common usage, oils rated 0 or 1 are described as non-comedogenic. That includes hemp seed, safflower, sunflower, argan, and mineral oils at 0, plus squalane, castor, and rosehip oils at 0 to 1. Strictly speaking, only a 0 means “will not clog pores,” so 1-rated oils are better described as very low risk.
Is coconut oil really bad for acne-prone skin?
On the face, usually yes for acne-prone skin: coconut oil is commonly rated 4 out of 5 and is one of the most frequently reported breakout triggers in natural skincare. Many people use it on the body or hair without issues. If you love it, keep it below the jawline and check that your facial products do not list it near the top.
Why do comedogenic ratings differ between websites?
Published ratings come from different sources, test methods, and oil grades; cold-pressed and refined versions of the same oil can behave differently. The original scale was also built on lab testing rather than real human faces. This hub follows one consistent source, the site’s own pore-clogging ingredients list, so every page here agrees with every other. When sites disagree, treat the number as an approximate risk signal rather than an exact measurement.
Can I use face oils if I have fungal acne?
Most plant oils are not ideal for fungal acne because Malassezia yeast feeds on many of their fatty acids, even when the comedogenic rating is low. Squalane is the widely recommended exception. Confirm what you are dealing with using our fungal acne guide first.
