Canola oil is not bad for your skin. In fact, its fatty acid profile and natural antioxidants make it a reasonable moisturizing option, and research suggests it may even help calm irritated or inflamed skin. The concern most people have comes from canola oil’s reputation as a heavily processed cooking oil, but when applied topically, the picture is quite different.
What Canola Oil Contains
Canola oil is roughly 65% oleic acid, a monounsaturated fat that absorbs well into the skin and helps soften it. It also contains about 16% linoleic acid, an omega-6 fatty acid that plays a direct role in maintaining the skin’s outer barrier, and around 7.5% alpha-linolenic acid, an omega-3 fat with anti-inflammatory properties. That combination gives canola oil a more balanced fatty acid profile than many plant oils used in skin care.
Beyond the fats, canola oil carries a small but meaningful fraction of compounds that benefit skin: phytosterols, which support wound healing and reduce inflammation, and tocopherols (a form of vitamin E), which act as antioxidants. These make up between 0.5% and 5% of the oil depending on how it’s processed.
How It Affects the Skin Barrier
Your skin’s outermost layer, the stratum corneum, relies on essential fatty acids to stay intact and hold moisture in. When that barrier weakens, water escapes more quickly (a measurement called transepidermal water loss), leading to dryness, flaking, and irritation. Linoleic acid, the omega-6 fat in canola oil, is one of the key building blocks of that barrier. Research on essential fatty acid deficiency shows that replenishing linoleic acid can restore barrier function in skin that has become compromised.
The omega-3 content in canola oil contributes differently. Rather than reinforcing the barrier directly, alpha-linolenic acid and its derivatives compete with inflammatory compounds in the skin, helping to tone down redness and swelling after irritation or sun exposure. A clinical trial comparing omega-3-rich flaxseed oil to an omega-6-rich oil found that both reduced transepidermal water loss, decreased skin roughness and scaling, and dampened the inflammatory response to chemical irritants.
Anti-Inflammatory Effects
One of the more surprising findings about canola oil is how well it performs against inflammation. Research from cosmetic laboratories testing canola oil on atopic dermatitis (eczema-prone skin) found that its soothing and anti-inflammatory properties were comparable to a 1% hydrocortisone cream, a mild steroid commonly used for skin irritation. The same research noted that canola oil-based products helped reduce redness in newborn skin, suggesting it’s gentle enough for even the most sensitive users.
A separate study looking at skin irritated by sodium lauryl sulfate (a harsh detergent used in lab settings to simulate irritation) found that a sterol-enriched fraction from canola oil significantly reduced visible signs of irritation compared to water alone. The phytosterols in canola oil appear to be doing much of this work, given their known anti-inflammatory and wound-healing activity.
Cold-Pressed vs. Refined
If you’re going to use canola oil on your skin, the type matters, at least in theory. Cold-pressed canola oil is extracted by slowly crushing the seeds without heat, which preserves more of the tocopherols, phytosterols, and other beneficial compounds. Refined canola oil, the kind sold for cooking, is typically produced with heat and chemical solvents, which can strip away some of those antioxidants. That said, no study has definitively proven that cold-pressed canola oil performs better on skin than refined versions. If you want to maximize the potential benefits, cold-pressed is the safer bet, but refined canola oil is unlikely to cause harm.
How It Compares to Other Oils
Canola oil sits in an interesting middle ground. Olive oil, the most popular plant oil in skin care, contains more oleic acid (up to 83% in some varieties) and higher levels of polyphenol antioxidants. That makes olive oil a richer emollient, but the high oleic acid concentration can actually be a drawback for people with already-compromised skin barriers. Some research has linked very high oleic acid content to mild barrier disruption in eczema-prone skin.
Canola oil’s lower oleic acid level and higher linoleic acid content may make it a gentler option for sensitive or dry skin. Oils with more linoleic acid tend to absorb without leaving a heavy residue and are less likely to clog pores. For oily or acne-prone skin, this balance could be an advantage over heavier oils like olive or coconut.
Coconut oil, by comparison, is roughly 82% saturated fat and sits on top of the skin rather than absorbing into it. It has antimicrobial properties but can be comedogenic (pore-clogging) for many people. Canola oil’s lighter texture and unsaturated fat profile make it less likely to trigger breakouts.
Potential Downsides
Canola oil is not a perfect skin care ingredient. It oxidizes more quickly than saturated fats, meaning it can go rancid if stored improperly. Rancid oil contains free radicals that can irritate skin and accelerate aging rather than prevent it. If your canola oil smells off or has been sitting open for months, don’t use it on your face.
Some people also react to trace proteins remaining in less-refined canola oil. True allergic reactions to topical canola oil are rare, but if you have a known sensitivity to rapeseed or mustard-family plants, patch test on a small area of your inner arm before applying it broadly. Wait 24 hours and check for redness or itching.
Finally, canola oil lacks some of the specialized compounds found in oils marketed specifically for skin care. It doesn’t contain the high polyphenol levels of extra virgin olive oil, the ceramide-like lipids in sunflower seed oil, or the retinol-like effects of rosehip oil. It works as a basic, affordable moisturizer and mild anti-inflammatory, but it won’t replace a targeted skin care product for specific concerns like hyperpigmentation or deep wrinkles.
