How to Choose a Facial Oil Without Trusting Comedogenic Charts

Choose a facial oil by what it does to your skin barrier and your pores, not by the skin type printed on the bottle. For dry skin, oils with more linoleic acid, such as sunflower seed oil, have better evidence than olive oil. If you're acne-prone, oily or getting itchy bumps, the best choice may be no oil.

You've probably seen the charts that score every oil for clogging pores. Maybe you picked one with a low score and still broke out along your jaw. Or you use the olive oil your mom swore by, and your cheeks still feel tight by lunch.

Is Olive Oil Good for Your Face?

Probably not, at least as a daily moisturizer for dry skin. A trial tested it on 19 adults with and without a history of eczema. Six drops twice a day on one forearm weakened the skin's outer layer within four weeks. It also caused mild redness.

In part of the trial, sunflower seed oil went on the other forearm. It did the opposite. It kept the outer layer intact, caused no redness and improved hydration. The researchers concluded that olive oil for dry skin and infant massage "should therefore be discouraged."

A forearm isn't a face, and 19 people is a small group. But the result fits what is known about the two fatty acids involved.

Why Linoleic Acid Matters More Than the Oil's Name

A 2018 review of plant oils on skin by Tzu-Kai Lin and colleagues explains the split. Linoleic acid helps keep the skin's water barrier intact. Oleic acid "causes barrier disruption and eventually induces dermatitis under continuous topical application."

Olive oil is mostly oleic acid. Sunflower oil has relatively more linoleic acid than olive oil, though the review doesn't give exact percentages. So two "natural, gentle" oils can behave very differently on the same skin.

Even sunflower oil isn't a free pass. In a pilot trial of 115 healthy full-term newborns, both olive and sunflower oil improved hydration over four weeks. Both also showed less improvement in the skin's lipid structure than using no oil at all. The authors advised caution with oils on newborn skin until there's more research.

For a baby, that means checking with a pediatrician before any oil massage. It's newborn skin, not an adult face, but it's a reminder that an oil can raise hydration without improving the barrier's structure. If that's the problem you're chasing, repairing a damaged skin barrier is a better starting point than a new bottle.

Do Comedogenic Ratings Tell You Which Oils Clog Pores?

Only roughly. Those ratings come from testing raw ingredients. A 2006 study in the Journal of the American Academy of Dermatology notes that animal models were originally used for that job.

The researchers then tested finished products on the upper backs of six people prone to clogged pores. Products made with comedogenic ingredients weren't necessarily comedogenic. Six people is tiny. Still, a rating on a raw ingredient doesn't reliably predict what the bottle in your hand will do.

Some warnings are worth keeping anyway. A Cleveland Clinic dermatologist says coconut oil is "highly comedogenic" and generally not recommended for the face. Lin's review lists coconut oil as about half lauric acid, and cites a study where virgin coconut oil helped children with mild to moderate eczema. That's body skin, in children, not an acne-prone adult face.

For acne-prone skin, Cleveland Clinic suggests skipping face oils altogether. If you use one anyway, a Cleveland Clinic dermatologist says products not labeled "noncomedogenic" may clog pores.

Is Facial Oil Good for Acne-Prone Skin?

Usually it's the riskier choice, with one interesting exception. In a month-long placebo-controlled trial in people with mild acne, linoleic acid on the skin shrank microcomedones by almost 25%. Those are the tiny clogs that come before pimples. Placebo sites didn't change.

That's one study, and it tested linoleic acid itself, not a face oil from a store shelf. It doesn't prove that a linoleic-rich oil will clear breakouts. It's an interesting lead, not a shopping list.

If you already break out, the honest default is a light, noncomedogenic moisturizer and no oil. Add one only if your skin stays dry, and only one at a time.

What If It's Fungal Acne?

Then oils can make it more likely. Fungal acne is an infection of the hair follicles with Malassezia, a yeast almost everyone carries. Cleveland Clinic lists "a lot of oil-based moisturizers and sunscreens" among its risk factors, along with hot, humid weather and antibiotics.

The clue is itch. Fungal acne shows up as clusters of small, itchy red bumps, often on the forehead, chin, chest or upper back, while ordinary acne usually doesn't itch. It needs antifungal treatment, which is different from what treats ordinary acne.

A 2023 letter in Skin Appendage Disorders cites a lab study where Malassezia grew in every oil tested, including olive and coconut oil. Each oil supported more growth than a fat-free control. That's a petri dish, not a person, and no clinical studies have tested it.

Still, if you have itchy bumps and use an oil, it's the first thing to stop.

Oils, Shea Butter and Darker Skin

On brown and Black skin, acne is often followed by dark spots, which the AAD calls hyperpigmentation. So an oil that clogs pores costs more than the pimple. The AAD's acne advice for darker skin warns that products with cocoa butter or shea butter can clog your pores.

The same AAD page says there's "absolutely no scientific evidence" that cocoa butter evens out skin tone. Clearing the acne is what prevents new dark spots. Why acne marks last longer on dark skin goes through what fades them.

Hair oil is the other source people miss. The AAD says that if acne appears only on your forehead and temples, your hair oil may be the cause. It suggests a water or glycerin-based product, or keeping oil to the middle of the scalp and the ends.

The 2023 letter suggests Black patients with seborrheic dermatitis keep oils off the scalp and focus on the lower lengths of the hair. Hair oiling for curly and coily hair covers how to do that.

Shea isn't useless. Lin's review describes a cream with shea butter extract that matched a ceramide-precursor product in eczema research. That's a cream for dry, eczema-prone skin, not a pure butter on an acne-prone face.

Which Facial Oil Suits Which Skin?

Sorted by what the research has actually tested, the common oils look like this:

• Sunflower seed oil: kept the skin's outer layer intact and improved hydration when compared side by side with olive oil in a small forearm trial.
• Olive oil: weakened the barrier in that same trial. Skip it on dry or eczema-prone skin.
• Jojoba: Lin's review calls its wax esters "a good repair option" for skin with a damaged barrier.
• Argan: in 60 postmenopausal women, argan oil on the forearm for 60 days improved skin elasticity. It wasn't tested on faces or acne-prone skin.
• Coconut oil: works as a body moisturizer, but skip it on your shoulders, chest and back if you're acne-prone. Not for an acne-prone face.
• Lavender, tea tree and other fragranced oils: a Cleveland Clinic dermatologist says these can irritate or act as allergens, so avoid strongly scented blends.

Cleveland Clinic advises skipping face oils on oily skin, partly because oily skin contributes to seborrheic dermatitis. If your face feels tight but looks shiny, check whether your skin is dry or dehydrated first, because oil won't add water.

How to Try a New Face Oil

Patch test it first. The AAD says to apply it twice daily for seven to 10 days to a quarter-sized spot, such as the bend of your elbow. Wash it off and stop if the skin turns red, itchy or swollen.

That test checks for irritation and allergy. It won't tell you about clogged pores on your face, so introduce one oil at a time and give it several weeks. A few drops is plenty. If you like a richer layer at night, slugging is a different approach with different risks.

When to See a Dermatologist

See a dermatologist if breakouts keep coming after you've cut back on oils, or if itchy bumps don't go away. The same goes for flaky, itchy patches on your face or scalp, and for dryness that a plain moisturizer doesn't fix. On darker skin, the AAD says treating acne early can stop it getting worse, and that more severe acne raises the risk of dark spots.

Frequently Asked Questions

Can I Use Facial Oil If I Have Oily Skin?

You can, but you probably don't need it. Cleveland Clinic advises skipping face oils on oily skin, since oily skin contributes to seborrheic dermatitis. If you want one anyway, choose a noncomedogenic product and watch for new breakouts over several weeks.

Is Tea Tree Oil Safe to Put on Your Face?

It's best avoided in face oils. A Cleveland Clinic dermatologist advises steering clear of strongly fragranced oils like tea tree and lavender because they can irritate skin or act as allergens. If you want to try a product containing it, patch test it first.

Does Facial Oil Cause Fungal Acne?

It can make it more likely. Cleveland Clinic lists heavy use of oil-based moisturizers and sunscreens as a risk factor. If you have small, itchy bumps that don't respond to acne products, stop the oil and see a doctor about antifungal treatment.
