Argan oil has been a culinary staple in Morocco for centuries — not only because of its subtle, nutty flavor but also its wide array of potential health benefits.
This naturally occurring plant oil is derived from the kernels of the fruit of the argan tree.
Although native to Morocco, argan oil is now used across the globe for a variety of culinary, cosmetic and medicinal applications.
This article explains 12 of the most prominent health benefits and uses of argan oil.
1. Contains Essential Nutrients
Argan oil is primarily comprised of fatty acids and a variety of phenolic compounds.
The majority of the fat content of argan oil comes from oleic and linoleic acid (1).
Approximately 29–36% of the fatty acid content of argan oil comes from linoleic acid, or omega-6, making it a good source of this essential nutrient (1).
Oleic acid, though not essential, makes up 43–49% of the fatty acid composition of argan oil and is also a very healthy fat. Found in olive oil as well, oleic acid is renowned for its positive impact on heart health (1, 2).
Additionally, argan oil is a rich source of vitamin E, which is required for healthy skin, hair and eyes. This vitamin also has powerful antioxidant properties (1).
Summary
Argan oil provides a good source of linoleic and oleic fatty acids, two fats known to support good health. It also boasts high levels of vitamin E.
2. Has Antioxidant and Anti-Inflammatory Properties
The various phenolic compounds in argan oil are likely responsible for most of its antioxidant and anti-inflammatory capacities.
Argan oil is rich in vitamin E, or tocopherol, a fat-soluble vitamin that serves as a potent antioxidant to reduce the damaging effects of free radicals (1).
Other compounds present in argan oil, such as CoQ10, melatonin and plant sterols, also play a role in its antioxidant capacity (3, 4, 5).
A recent study revealed a significant reduction in inflammatory markers in mice fed argan oil prior to exposure to a highly inflammatory liver toxin, compared to the control group (6).
Additionally, some research indicates that argan oil can also be applied directly to your skin to reduce inflammation caused by injuries or infections (7).
Although these results are encouraging, more research is needed to understand how argan oil can be used medicinally in humans to reduce inflammation and oxidative stress.
Summary
Multiple compounds in argan oil may help reduce inflammation and oxidative stress, though more research is needed.
3. May Boost Heart Health
Argan oil is a rich source of oleic acid, which is a monounsaturated, omega-9 fat (1).
Oleic acid is also present in several other foods, including avocado and olive oils, and is often credited with heart-protective effects (2, 8).
One small human study noted that argan oil was comparable to olive oil in its capacity to reduce heart disease risk through its impact on antioxidant levels in the blood (9).
In another small human study, a higher intake of argan oil was associated with lower levels of "bad" LDL cholesterol and higher blood levels of antioxidants (10).
In a study on heart disease risk in 40 healthy people, those who consumed 15 grams of argan oil daily for 30 days experienced a 16% and 20% reduction in "bad" LDL and triglyceride levels, respectively (11).
Although these results are promising, larger studies are necessary to better understand how argan oil may support heart health in humans.
Summary
Argan oil's fatty acids and antioxidants may help reduce heart disease risk, though more research is needed.
4. May Have Benefits for Diabetes
Some early animal research indicates argan oil may help prevent diabetes.
Two studies resulted in a significant reduction in both fasting blood sugar and insulin resistance in mice fed a high-sugar diet alongside argan oil (12, 13).
These studies largely attributed these benefits to the antioxidant content of the oil.
However, such results do not necessarily imply that the same effects would be seen in humans. Therefore, human research is needed.
Summary
Some animal studies indicate argan oil may reduce blood sugar and insulin resistance to help prevent diabetes. That said, human studies are lacking.
5. May Have Anticancer Effects
Argan oil may slow the growth and reproduction of certain cancer cells.
One test-tube study applied polyphenolic compounds from argan oil to prostate cancer cells. The extract inhibited cancer cell growth by 50% compared to the control group (14).
In another test-tube study, a pharmaceutical-grade mixture of argan oil and vitamin E increased the rate of cell death on breast and colon cancer cell samples (15).
Although this preliminary research is intriguing, more research is needed to determine whether argan oil could be used to treat cancer in humans.
Summary
Some test-tube studies revealed potential cancer-fighting effects of argan oil, though more studies are needed.
6. May Reduce Signs of Skin Aging
Argan oil has quickly become a popular ingredient for many skin care products.
Some research suggests that dietary intake of argan oil may help slow the aging process by reducing inflammation and oxidative stress (16).
It may also support repair and maintenance of healthy skin when applied directly to your skin, thus reducing visual signs of aging (7).
Some human studies show argan oil — both ingested and administered directly — to be effective for increasing skin elasticity and hydration in postmenopausal women (17, 18).
Ultimately, more human research is needed.
Summary
A few small studies indicate that argan oil may be effective at reducing signs of aging, either when ingested or applied directly to your skin.
7. May Treat Some Skin Conditions
Argan oil has been a popular home remedy for treating inflammatory skin conditions for decades — especially in North Africa, where argan trees originate.
Although there's limited scientific evidence supporting argan oil's ability to treat specific skin infections, it is still frequently used for this purpose.
However, current research indicates that argan oil does contain several antioxidant and anti-inflammatory compounds, which may be why it seems to treat skin tissue (7).
Keep in mind that more research is needed.
Summary
While argan oil has been traditionally used to treat skin infections, there is limited evidence to support this. That said, anti-inflammatory compounds may benefit skin tissue.
8. May Promote Wound Healing
Argan oil may accelerate the wound healing process.
One animal study revealed a significant increase in wound healing in rats given argan oil on their second-degree burns twice daily for 14 days (19).
Although this data doesn't prove anything with certainty, it does indicate a possible role for argan oil in wound healing and tissue repair.
That said, human research is needed.
Summary
In one animal study, argan oil applied to burn wounds accelerated healing. However, human research is needed.
9. May Moisturize Skin and Hair
The oleic and linoleic acids that make up the majority of argan oil's fat content are vital nutrients for maintaining healthy skin and hair (1, 20).
Argan oil is often directly administered to skin and hair but may also be effective when ingested.
In one study, both oral and topical applications of argan oil improved the moisture content of the skin in postmenopausal women (18).
Although there isn't any research on the specific use of argan oil for hair health, some studies indicate that other plant oils with a comparable nutritional profile may reduce split ends and other types of hair damage (21).
Summary
Argan oil is popularly used to moisturize skin and hair. Some research indicates the fatty acids in argan oil may support healthy, hydrated skin and reduce hair damage.
10. Often Used to Treat and Prevent Stretch Marks
Argan oil is frequently used to prevent and reduce stretch marks, although no research has been conducted to prove its efficacy.
In fact, there is no strong evidence that any kind of topical treatment is an effective tool for stretch mark reduction (22).
However, research does indicate that argan oil may help reduce inflammation and improve the elasticity of skin — which could be why so many people report success in using it for stretch marks (7, 17).
Summary
Argan oil is often used as a remedy for treating stretch marks, although no scientific data supports this.
11. Sometimes Used to Treat Acne
Some sources claim argan oil to be an effective treatment for acne, although no rigorous scientific research supports this.
That said, argan oil's antioxidant and anti-inflammatory compounds may support reduced redness and irritation of the skin caused by acne (7, 23).
The oil also may contribute to skin hydration, which is important for acne prevention (18).
Whether argan oil is effective in treating your acne likely depends on its cause. If you struggle with dry skin or general irritation, argan oil may provide a solution. However, if your acne is caused by hormones, argan oil will not likely provide significant relief.
Summary
Though some people claim that argan oil is effective for treating acne, no studies support this. However, it may reduce redness and soothe irritation caused by acne.
12. Easy to Add to Your Routine
As argan oil has become increasingly popular, it's easier than ever to add it to your health and beauty routine.
It is widely available in most major grocery stores, drug stores and online retailers.
For Skin
Argan oil is usually used topically in its pure form — but also frequently included in cosmetic products like lotions and skin creams.
While it can be applied directly to your skin, it may be best to start with a very small amount to ensure that you won't have any adverse reactions.
For Hair
You can apply argan oil directly to damp or dry hair to improve moisture, reduce breakage, or reduce frizz.
It is also sometimes included in shampoos or conditioners.
If it's your first time using it, start with a small amount to see how your hair responds. If you have naturally oily roots, apply argan only to the ends of your hair to avoid greasy-looking hair.
For Cooking
If you're interested in using argan oil with food, look for varieties specifically marketed for cooking, or make sure you're buying 100% pure argan oil.
Argan oil marketed for cosmetic purposes may be mixed with other ingredients that you shouldn't ingest.
Traditionally, argan oil is used for dipping bread or drizzling on couscous or vegetables. It can also be lightly heated, but it is not appropriate for high-heat dishes as it can easily burn.
Summary
Because of its recent rise in popularity, argan oil is widely available and easy to use for skin, hair and food.
The Bottom Line
Argan oil has been used for centuries for a variety of culinary, cosmetic and medicinal purposes.
It is rich in essential nutrients, antioxidants and anti-inflammatory compounds.
Early research indicates that argan oil may help prevent chronic illnesses, including heart disease, diabetes and cancer. It may also treat a variety of skin conditions.
While current research cannot definitively state that argan oil is effective for treating any of these conditions, many people report desirable results after using it.
If you're curious about argan oil, it's easy to find and start using today.

Thousands of Superfund sites exist around the U.S., with toxic substances left open, mismanaged and dumped. Despite the high levels of toxicity at these sites, nearly 21 million people live within a mile of one of them, according to the U.S. Environmental Protection Agency (EPA).
Currently, more than 1,300 Superfund sites pose a serious health risk to nearby communities. Based on a new study, residents living close to these sites could also have a shorter life expectancy.
Published in Nature Communications, the study, led by Hanadi S. Rifai, a professor of civil and environmental engineering at the University of Houston, and a team of researchers, found that living in nearby zip codes to Superfund sites resulted in a decreased life expectancy of more than two months, the University of Houston reported.
"We have ample evidence that contaminant releases from anthropogenic sources (e.g., petrochemicals or hazardous waste sites) could increase the mortality rate in fence-line communities," Rifai told the University of Houston. "Results showed a significant difference in life expectancy among census tracts with at least one Superfund site and their neighboring tracts with no sites."
The study pulled data from 65,000 census tracts – defined geographical regions – within the contiguous U.S., The Guardian reported. With this data, researchers found that for communities that are socioeconomically challenged, this life expectancy could decrease by up to a year.
"It was a bit surprising and concerning," Rifai told The Guardian. "We weren't sure [when we started] if the fact that you are socioeconomically challenged would make [the Superfund's effects] worse."
The research team, for example, found that the presence of a Superfund site in a census tract with a median income of less than $52,580 could reduce life expectancy by seven months, the University of Houston reported.
Many of these toxic sites were once used as manufacturing sites during the Second World War. Common toxic substances that are released from the sites into the air and surface water include lead, trichlorethylene, chromium, benzene and arsenic – all of which can lead to health impacts, such as neurological damage among children, The Union of Concerned Scientists wrote in a blog.
"The EPA has claimed substantial recent progress in Superfund site cleanups, but, contrary to EPA leadership's grandiose declarations, the backlog of unfunded Superfund cleanups is the largest it has been in the last 15 years," the Union wrote.
Delayed cleanup could become increasingly dangerous as climate change welcomes more natural hazards, like wildfires and flooding. According to a Government Accountability Office report, for example, climate change could threaten at least 60 percent of Superfund sites in the U.S., AP News reported.
During the summer of 2018, a major wildfire took over the Iron Mountain Superfund site near Redding, CA, ruining wastewater treatment infrastructure that is responsible for capturing 168 million gallons of acid mine drainage every month, NBC News reported.
"There was this feeling of 'My God. We ought to have better tracking of wildfires at Superfund locations,'" Stephen Hoffman, a former senior environmental scientist at the EPA, told NBC News. "Before that, there wasn't a lot of thought about climate change and fire. That has changed."
In the study, researchers also looked at the impacts of floodings on Superfund sites, which could send toxins flowing into communities and waterways.
"When you add in flooding, there will be ancillary or secondary impacts that can potentially be exacerbated by a changing future climate," Rifai told the University of Houston. "The long-term effect of the flooding and repetitive exposure has an effect that can transcend generations."

A weather research station on a bluff overlooking the sea is closing down because of the climate crisis.
The National Weather Service (NWS) station in Chatham, Massachusetts was evacuated March 31 over concerns the entire operation would topple into the ocean.
"We had to say goodbye to the site because of where we are located at the Monomoy Wildlife Refuge, we're adjacent to a bluff that overlooks the ocean," Boston NWS meteorologist Andy Nash told WHDH at the time. "We had to close and cease operations there because that bluff has significantly eroded."
Chatham is located on the elbow of Cape Cod, a land mass extending out into the Atlantic Ocean that has been reshaped and eroded by waves and tides over tens of thousands of years, The Guardian explained. However, sea level rise and extreme weather caused by the climate crisis have sped that change along.
"It's an extremely dynamic environment, which is obviously a problem if you are building permanent infrastructure here," Andrew Ashton, an associate scientist at Cape-Cod based Woods Hole Oceanographic Institution, told The Guardian. "We are putting our foot on the accelerator to make the environment even more dynamic."
This was the case with the Chatham weather station. It used to be protected from the drop into the ocean by about 100 feet of land. However, storm action in 2020 alone washed away as much as six feet of land a day.
"We'd know[n] for a long time there was erosion but the pace of it caught everyone by surprise," Nash told The Guardian. "We felt we had maybe another 10 years but then we started losing a foot of a bluff a week and realized we didn't have years, we had just a few months. We were a couple of storms from a very big problem."
The Chatham station was part of a network of 92 NWS stations that monitor temperature, pressure, humidity, wind speed and direction and other data in the upper atmosphere, The Cape Cod Chronicle explained. The stations send up radiosondes attached to weather balloons twice a day to help with weather research and prediction. The Chatham station, which had been observing this ritual for the past half a century, sent up its last balloon the morning of March 31.
"We're going to miss the observations," Nash told The Cape Cod Chronicle. "It gives us a snapshot, a profile of the atmosphere when the balloons go up."
The station was officially decommissioned April 1, and the two buildings on the site will be demolished sometime this month. The NWS is looking for a new location in southeastern New England. In the meantime, forecasters will rely on data from stations in New York and Maine.
Nash said the leavetaking was bittersweet, but inevitable.
"[M]other nature is evicting us," he told The Cape Cod Chronicle.

- If online deliveries continue with fossil-fuel trucks, emissions will increase by a third.
- So cities in the Netherlands will allow only emission-free delivery vehicles after 2025.
- The government is giving delivery firms cash help to buy or lease electric vehicles.
- The bans will save 1 megaton of CO2 every year by 2030.
Cities in the Netherlands want to make their air cleaner by banning fossil fuel delivery vehicles from urban areas from 2025.
"Now that we are spending more time at home, we are noticing the large number of delivery vans and lorries driving through cities," said Netherlands environment minister Stientje van Veldhoven, announcing plans to ban all but zero-emission deliveries in 14 cities.
"The agreements we are setting down will ensure that it will be a matter of course that within a few years, supermarket shelves will be stocked, waste will be collected, and packages will arrive on time, yet without any exhaust fumes and CO2 emissions," she added.
She expects 30 cities to announce zero emission urban logistics by this summer. City councils must give four years' notice before imposing bans as part of government plans for emission-free road traffic by 2050. The city bans aim to save 1 megaton of CO2 each year by 2030.
Help to Change
To encourage transport organizations to go carbon-free, the government is offering grants of more than US$5,900 to help businesses buy or lease electric vehicles. There will be additional measures to help small businesses make the change.
The Netherlands claims it is the first country in the world to give its cities the freedom to implement zero-emission zones. Amsterdam, Rotterdam and Utrecht already have "milieuzones" where some types of vehicles are banned.
Tilburg, one of the first wave of cities imposing the Dutch ban, will not allow fossil-fuelled vehicles on streets within its outer ring road and plans to roll out a network of city-wide electric vehicle charging stations before the ban comes into effect in 2025.
"Such initiatives are imperative to improve air quality. The transport of the future must be emission-free, sustainable, and clean," said Tilburg city alderman Oscar Dusschooten.
Europe Takes Action
Research by Renault shows that many other European cities are heading in the same direction as the Netherlands, starting with Low Emission Zones of which Germany's "Umweltzone" were pioneers. More than 100 communes in Italy have introduced "Zonas a traffico limitato."
Madrid's "zona de baja emisión" bans diesel vehicles built before 2006 and petrol vehicles from before 2000 from central areas of the city. Barcelona has similar restrictions and the law will require all towns of more than 50,000 inhabitants to follow suit.
Perhaps the most stringent restrictions apply in London's Ultra Low Emission Zone (ULEZ), which charges trucks and large vehicles up to US$137 a day to enter the central area if they do not comply with Euro 6 emissions standards. From October, the ULEZ is being expanded.
Cities are responsible for around 75% of CO2 emissions from global final energy use, according to the green thinktank REN21 - and much of these come from transport. Globally, transport accounts for 24% of world CO2 emissions.
The Rise of Online Shopping
Part of the reason for traffic in urban areas is the increase in delivery vehicles, as online shopping continues to grow. Retailer ecommerce sales are expected to pass $5billion in 2022, according to eMarketer.
The World Economic Forum's report The Future of the Last-Mile Ecosystem, published in January 2020, estimates that e-commerce will increase the number of delivery vehicles on the roads of the world's 100 largest cities by 36% by 2030.
If all those vehicles burn fossil fuels, the report says emissions will increase by 32%. But switching to all-electric delivery vehicles would cut emissions by 30% from current levels as well as reducing costs by 25%, the report says.
Other solutions explored in the report include introducing goods trams to handle deliveries alongside their passenger-carrying counterparts and increased use of parcel lockers to reduce the number of doorstep deliveries.

A bill that would have banned fracking in California died in committee Tuesday.
The bill, SB467, would have prohibited fracking and other controversial forms of oil extraction. It would also have banned oil and gas production within 2,500 feet of a home, school, hospital or other residential facility. The bill originally set the fracking ban for 2027, but amended it to 2035, The AP reported.
"Obviously I'm very disappointed," State Sen. Scott Wiener (D-San Francisco), one of the bill's two introducers, told the Los Angeles Times. "California really has not done what it needs to do in terms of addressing the oil problem. We have communities that are suffering right now, and the Legislature has repeatedly failed to act."
The bill was introduced after California Gov. Gavin Newsom said he would sign a fracking ban if it passed the legislature, though his administration has continued to issue permits in the meantime, Forbes reported. Newsom has also spoken in favor of a buffer zone between oil and gas extraction and places where people live and learn, according to the Los Angeles Times. The latter is a major environmental justice issue, as fossil fuel production is more likely to be located near Black and Latinx communities.
Urban lawmakers who want California to lead on the climate crisis supported the bill, while inland lawmakers in oil-rich areas concerned about jobs opposed it. The oil and gas industry and trade unions also opposed the bill.
This opposition meant the bill failed to get the five votes it needed to move beyond the Senate's Natural Resources and Water Committee. Only four senators approved it, while Democrat Sen. Susan Eggman of Stockton joined two Republicans to oppose it, and two other Democrats abstained.
Eggman argued that the bill would have forced California to rely on oil extracted in other states.
"We're still going to use it, but we're going to use it from places that produce it less safely," Eggman told The AP. She also said that she supported the transition away from fossil fuels, but thought the bill jumped the gun. "I don't think we're quite there yet, and this bill assumes that we are," she added.
Historically, California has been a major U.S. oil producer. Its output peaked in 1986 at 1.1 million barrels a day, just below Texas and Alaska, according to Forbes. However, production has declined since then making it the seventh-most oil-producing state.
Still, California's fossil fuel industry is at odds with state attempts to position itself as a climate leader.
"There is a large stain on California's climate record, and that is oil," Wiener said Tuesday, according to The AP.
Wiener and Democrat co-introducer Sen. Monique Limón from Santa Barbara vowed to keep fighting.
"While we saw this effort defeated today, this issue isn't going away," they wrote in a joint statement. "We'll continue to fight for aggressive climate action, against harmful drilling, and for the health of our communities."

World's 5% 'Polluter Elite' Responsible for 37% of Global Emissions Growth, Study Concludes
By Brett Wilkins
As world leaders prepare for this November's United Nations Climate Conference in Scotland, a new report from the Cambridge Sustainability Commission reveals that the world's wealthiest 5% were responsible for well over a third of all global emissions growth between 1990 and 2015.
The report, Changing Our Ways: Behavior Change and the Climate Crisis, found that nearly half the growth in absolute global emissions was caused by the world's richest 10%, with the most affluent 5% alone contributing 37%.
"In the year when the UK hosts COP26, and while the government continues to reward some of Britain's biggest polluters through tax credits, the commission report shows why this is precisely the wrong way to meet the UK's climate targets," the report's introduction states.
The authors of the report urge United Kingdom policymakers to focus on this so-called "polluter elite" in an effort to persuade wealthy people to adopt more sustainable behavior, while providing "affordable, available low-carbon alternatives to poorer households."
The report found that the "polluter elite" must make "dramatic" lifestyle changes in order to meet the UK's goal — based on the Paris climate agreement's preferential objective — of limiting global heating to 1.5°C, compared with pre-industrial levels.
In addition to highlighting previous recommendations — including reducing meat consumption, reducing food waste, and switching to electric vehicles and solar power — the report recommends that policymakers take the following steps:
- Implement frequent flyer levies;
- Enact bans on selling and promoting SUVs and other high polluting vehicles;
- Reverse the UK's recent move to cut green grants for homes and electric cars; and
- Build just transitions by supporting electric public transport and community energy schemes.
"We have got to cut over-consumption and the best place to start is over-consumption among the polluting elites who contribute by far more than their share of carbon emissions," Peter Newell, a Sussex University professor and lead author of the report, told the BBC.
"These are people who fly most, drive the biggest cars most, and live in the biggest homes which they can easily afford to heat, so they tend not to worry if they're well insulated or not," said Newell. "They're also the sort of people who could really afford good insulation and solar panels if they wanted to."
Newell said that wealthy people "simply must fly less and drive less. Even if they own an electric SUV, that's still a drain on the energy system and all the emissions created making the vehicle in the first place."
"Rich people who fly a lot may think they can offset their emissions by tree-planting schemes or projects to capture carbon from the air," Newell added. "But these schemes are highly contentious and they're not proven over time."
The report concludes that "we are all on a journey and the final destination is as yet unclear. There are many contradictory road maps about where we might want to get to and how, based on different theories of value and premised on diverse values."
"Promisingly, we have brought about positive change before, and there are at least some positive signs that there is an appetite to do what is necessary to live differently but well on the planet we call home," it states.
The new report follows a September 2020 Oxfam International study that revealed the wealthiest 1% of the world's population is responsible for emitting more than twice as much carbon dioxide as the poorest 50% of humanity combined.
