Unlocking Argan Oil’s Beauty Secrets: Chemistry and Therapeutic Marvels


Argan oil is a prized beauty product that has been used for centuries by the Berber women of Morocco. Native to the arid regions of Morocco, argan oil is extracted from the kernels of the argan tree (Argania spinosa). This uniquely North African oil contains an impressive mix of fatty acids, antioxidants, and other skin-nourishing compounds. While argan oil has long been a staple of Moroccan beauty rituals, the rest of the world is just now discovering its remarkable benefits. In this blog post, I will discuss argan oil’s chemistry and uncover the scientific reasons why it works wonders on skin and hair. I’ll also explore its therapeutic properties and growing popularity as a multi-purpose natural remedy. My goal is to provide an in-depth look at this precious oil and help unlock the secrets behind its revered status in natural skin and hair care.

Chemical Composition

The components that give argan oil its prized qualities come down to its unique fatty acid profile and antioxidant content. Let’s take a closer look at argan oil’s key chemical constituents and how they contribute to its therapeutic effects.

Fatty Acids

  • Oleic acid (40-50%): Monounsaturated fatty acid that is a major component of many nourishing plant oils. It helps maintain theskin’s protective acid mantle and keeps moisture locked in.
  • Linoleic acid (30-40%): Essential polyunsaturated omega-6 fatty acid that supports skin health and hydration.
  • Palmitic acid (10-15%): Saturated fatty acid that enhances the skin’s permeability barrier.
  • Stearic acid (3-8%): Saturated fatty acid with emollient properties that soothe and condition skin/hair.

This fatty acid profile makes argan oil highly moisturizing and able to effectively penetrate skin/hair without clogging pores. The high oleic acid content is similar to olive oil, giving argan oil its acclaimed skin reparative abilities.


Argan oil contains four forms of vitamin E (alpha, beta, gamma, and delta tocopherols) that act as powerful antioxidants. Tocopherols neutralize free radicals and environmental stressors to prevent premature skin aging. They also support collagen production for youthful, supple skin.

Phenolic Compounds

Phenolic compounds including catechins, epicatechins, and gallic acid make argan oil a very stable antioxidant. These phytonutrients have anti-inflammatory and antimicrobial properties that keep skin clear and healthy.


Argan oil rivals olive oil in its high squalene content, averaging 7-9%. Squalene is a precursor to healthy sebum production that maintains skin’s acid mantle and elasticity. It locks in moisture and protects against oxidative damage as well.


Plant sterols like beta-sitosterol support the skin’s natural repair mechanisms, reducing dryness, scaling, and itching. They calm inflammation and irritation.

In summary, argan oil’s unique combination of fatty acids, vitamins, polyphenols, squalene, and sterols give it unmatched nourishing, protective, and regenerative powers for skin and hair. This chemical profile explains why argan oil delivers such dramatic results.

Skin Benefits

With its emollient, anti-aging, and regenerative properties, argan oil offers a multitude of impressive skin benefits:

  • Moisturizes and Softens
    Argan oil’s fatty acid content and ability to penetrate skin make it one of the most hydrating natural oils. It restores suppleness and relief to dry, irritated skin.
  • Reduces Appearance of Scarring and Stretch Marks
    Argan oil boosts collagen production and cell regeneration to improve the texture and pigmentation of scars and stretch marks over time.
  • Protects Against UV Damage and Premature Aging
    The high antioxidant levels in argan oil protect against sun damage and neutralize free radicals responsible for sunspots, wrinkles, and dark spots.
  • Fades Stubborn Age Spots and Discoloration
    Regular application of argan oil helps gradually fade existing hyperpigmentation due to its skin-lightening and restorative properties.
  • Soothes Eczema, Dermatitis, and Psoriasis
    Argan oil’s anti-inflammatory activity and skin-repairing fatty acids relieve redness/flakiness of irritated skin conditions.
  • Controls Breakouts and Reduces Blemishes
    Its antibacterial compounds and non-comedogenic nature make argan oil ideal for oily/acne-prone skin without clogging pores.
  • Heals Cracked Heels and Cuticles
    Argan oil penetrates to moisturize severely dry, hardened areas and protects against tearing or fissuring.
  • Improves Stretch Mark Appearance After Childbirth
    When massaged consistently into maturing stretch marks, argan oil helps improve their texture and fade discoloration over time.

As you can see, argan oil handles a wide range of skin challenges with minimal effort. Its nourishing, restorative chemistry and antioxidant protection give radiant, youthful-looking results. No wonder Moroccan women have trusted it for centuries!

Hair Benefits

Not only is argan oil excellent for skin, it also works wonders on hair due to its ability to penetrate the hair shaft. Here are some notable benefits:

  • Hydrates and Softens Hair
    Argan oil deeply moisturizes hair, leaving it silky, shiny and manageable without residue or greasiness.
  • Reduces Frizz and Flyaways
    The oil forms a barrier on hair to seal in moisture and protect against environmental damage that causes frizz.
  • Strengthens and Promotes Growth
    Essential fatty acids in argan oil nourish follicles for thicker, stronger hair that grows faster and to a healthier length.
  • Prevents Split Ends
    Argan oil seals cuticles so hair fibers aren’t compromised from daily abuse like heat styling or brushing.
  • Smooths Cuticle Layers
    Leading to a visibly smoother, sleeker texture by eliminating friction between hair strands.
  • Adds Sumptuous Shine
    Antioxidants protect hair color from fading while the oil’s high vitamin E content leaves hair with a glossy sheen.
  • Repairs Damage From Over-Processing
    Its restorative properties reconstruct broken bonds in over-bleached, color-treated, or heat styled hair.
  • Fades Brassy Undertones
    Argan oil’s natural pigments reduce unwanted tones caused by over-lightening or toners going wrong.

By treating hair with argan oil regularly, you give it staying power against the daily damage we subject it to. Hair stays hydrated, protected and left with a silky quality that shampoos and conditioners alone can’t provide.

Therapeutic Uses

Argan oil’s skin and hair benefits are well-known, but it also boasts promising therapeutic applications thanks to biologically active compounds:

  • Anti-inflammatory and Antibacterial
    Argan oil’s phenolic compounds work to reduce redness and soothe irritation from insect bites, cuts, rashes and minor burns. Its antibacterial properties speed wound/cut healing by preventing infection.
  • Stress-Fighting Antioxidants
    Oil massage eases tension, and argan oil’s high vitamin E and phenolic content protect against cell-damaging oxidation associated with stress. This nourishes the adrenals.
  • Heart Health Promoter
    Studies show argan oil consumption supports cardiovascular health by lowering LDL cholesterol and blood pressure when included in a balanced diet.
  • Anti-Diabetic Properties
    Argan extracts may aid insulin sensitivity and help regulate blood sugar levels based on animal findings hinting at anti-diabetic effects.
  • Enhances Brain Function
    Vitamin E from argan oil is essential for nervous system health. Research also suggests its sterols impact cognitive decline and mood-related disorders like depression.

In the future, argan oil has potential to impact conditions like eczema, psoriasis, acne and skin cancer once more clinical trials are conducted. But already it has proven anti-aging benefits for whole-body wellness when used topically or taken orally in moderation. Its therapeutic powers are becoming more recognized with scientific research.

FAQ 1: Is argan oil good for acne-prone skin?

Argan oil is actually quite suitable for acne-prone skin as it is non-comedogenic, meaning it won’t clog pores. Its antibacterial properties help fight the bacteria that contributes to breakouts. The oil also helps regulate sebum production and reduces inflammation. Start with a small amount and see if your skin tolerates it before applying over large areas. Some people notice their acne clear up significantly with regular argan oil use.

FAQ 2: How do you use argan oil on hair?

For hair, massage a dime-sized amount onto damp or dry strands, focusing on the ends. You can also add a few drops to your conditioner. Leave it on for at least 30 minutes before rinsing hair or allow it to air dry if leaving it in. Use argan oil 2-3 times per week for best results in hydrating hair and strengthening roots. It works well as a heat protector before blow drying or styling as well.

FAQ 3: Can argan oil help diminish stretch marks?

Yes, argan oil has shown promise for improving the appearance of old or new stretch marks due to its high vitamin E, phenol, and fatty acid content. These nourish skin from within and boost collagen production. Massage a small amount directly onto marks once or twice daily, being gentle on new marks. It may take regular application for several months to see results, as stretch marks fade gradually. But argan oil can noticeably soften and fade marks over time with consistency.

FAQ 4: How do you know if argan oil is rancid?

Rancid argan oil will have an unpleasant, acidic or fishy smell instead of a pleasant nutty aroma. It may also be discolored ranging from pale yellow to deep orange or brown. Rancid oil should not be used as it can cause acne breakouts and other skin irritations. Be sure to purchase argan oil from a trusted brand and store it in a cool, dark place, like the refrigerator, to maintain freshness for 1-2 years.

FAQ 5: Can too much argan oil cause breakouts?

It’s possible to overdo it with argan oil if you have very oily or acne-prone skin. Start with a small amount, about the size of a pea, and slowly increase usage as needed. Look for any signs of new breakouts. If pimples appear, scale back to using argan oil 1-2 times per week instead of daily. And always patch test new products in case your skin doesn’t agree with an ingredient. Less is more when it comes to any natural oil, including argan.

FAQ 6: How does argan oil compare to other oils?

While all oils moisturize to some degree, argan oil stands out for its nutrient-dense composition of lipids, antioxidants and beneficial fatty acids. It penetrates pores better than thicker plant oils yet is still deeply hydrating. Oils high in oleic acid like argan and marula are best for dry skin. For problematic skin, tea tree and lavender oils are antibacterial. Hemp seed oil is light and non-greasy. Overall, argan oil is among the most reparative and multi-purpose carrier oils available.


There’s no doubt that argan oil is a highly effective natural skincare and haircare ingredient. Thanks to its rich chemical profile, antioxidant power and ability to nourish from within, it delivers impressively transformative results. Whether you apply argan oil to remedy dryness, minimize signs of aging, or simply pamper skin and locks, you can expect radiant, healthy-looking benefits. As popularity and research around this “liquid gold” from Morocco continues to grow, argan oil’s versatility for beauty, wellness and therapeutic use is sure to astound us further. Its proven record of moisturizing and revitalizing makes it a must-have for any natural beauty lovers cabinet.
