Emu oil scores a 0 to 1 on the comedogenic scale, which ranges from 0 (won’t clog pores) to 5 (highly likely to clog pores). By this measure, it is one of the least pore-clogging oils you can put on your skin. Most people, including those with oily or breakout-prone skin, can use it without expecting new clogged pores or blackheads.
What the Comedogenic Rating Means
The comedogenic scale ranks oils and ingredients from 0 to 5 based on how likely they are to block pores and cause comedones (blackheads and whiteheads). A rating of 0 means the ingredient is considered non-comedogenic. A rating of 1 means there’s a very low probability of clogging. Emu oil lands in this range depending on the source, with some databases listing it at 0 and others at 1.
For context, jojoba oil, often recommended as a safe facial oil, sits at a 2. Argan oil rates a 0. Coconut oil, which is notorious for causing breakouts, scores a 4. Emu oil is comfortably in the same territory as oils widely considered safe for the face.
Why Emu Oil Doesn’t Clog Pores
The main reason comes down to how the oil interacts with skin. Research using infrared imaging has shown that emu oil penetrates roughly 270 micrometers deep into the skin surface, passing through the outer barrier rather than sitting on top of it. Most pore-clogging oils form a film over the skin that traps dead cells and sebum inside follicles. Emu oil does something different: its unsaturated fatty acids actually disrupt the tightly packed structure of keratin, the protein that makes up your outer skin layer. This loosening effect lets the oil absorb into deeper layers instead of pooling in pores.
The fatty acid profile helps explain this behavior. Emu oil is roughly 46% oleic acid, a monounsaturated fat that skin readily absorbs because it closely resembles the fatty acids your skin already produces. It also contains linoleic acid, which is the fatty acid that acne-prone skin tends to be deficient in. People with oily, breakout-prone skin often have lower linoleic acid levels in their sebum, which makes their natural oil thicker and stickier. Applying linoleic acid topically can help normalize sebum consistency.
Effects on Acne-Prone Skin
Beyond simply not clogging pores, emu oil has properties that may actively help skin that’s prone to breakouts. The linoleic acid content has been linked to reduced appearance of acne scars over time. But the more significant finding is emu oil’s anti-inflammatory activity.
A study published in the Journal of Functional Foods found that emu oil reduces inflammation in skin by shifting the behavior of immune cells called macrophages. Specifically, it encourages these cells to switch from a pro-inflammatory state to an anti-inflammatory one. In practical terms, this means emu oil can calm redness and swelling. The study showed it suppressed key inflammatory signals while boosting the production of anti-inflammatory compounds. In wound-healing experiments, emu oil accelerated wound closure, improved new skin formation, and enhanced collagen production.
For someone dealing with acne, this anti-inflammatory effect matters. Much of acne’s visible damage, the redness, swelling, and eventual scarring, comes from inflammation rather than the clogged pore itself. An oil that penetrates well, doesn’t block pores, and actively reduces inflammation is a useful combination.
Quality and Purity Matter
Not all emu oil products are equal, and this is where the comedogenic rating can become misleading. Pure, refined emu oil earns that low score. But many products on the market blend emu oil with other ingredients, fragrances, or carrier oils that may have higher comedogenic ratings. Some lower-quality emu oil is also poorly refined, leaving behind impurities that can irritate skin or contribute to clogged pores.
If you’re using emu oil specifically because of its low comedogenic rating, look for products labeled as fully refined or that carry certification from the American Emu Association. The oil should be a pale, nearly odorless liquid at room temperature. If it has a strong smell or a deep yellow color, it may not be adequately processed.
How to Patch Test
Even with a comedogenic rating near zero, individual skin reactions vary. Some people break out from oils that are technically non-comedogenic, because comedogenic ratings are population averages, not guarantees for every person. Apply a small amount of emu oil to a discreet area of your face, like near your jawline, for five to seven days. If you don’t see new clogged pores or irritation, it’s generally safe to incorporate into your routine more broadly. A few drops go a long way since the oil absorbs quickly and doesn’t need to be layered on heavily.
