Rosehip oil and argan oil are two of the most popular facial oils in natural skincare, and both have genuine evidence behind them. But they have quite different fatty acid profiles, different textures, and different strengths. Choosing between them is not a matter of which is “better” in the abstract but which one suits your skin type and primary concern.
Rosehip oil: the high-linoleic option
Rosehip seed oil (Rosa canina or Rosa rubiginosa seed oil) is pressed from the seeds of rose hips, the fruit that remains after the petals drop. It is a deep golden-red oil with a characteristic earthy, slightly nutty scent.
The fatty acid profile is dominated by linoleic acid (35-45%) and alpha-linolenic acid (30-35%), making it one of the most polyunsaturated of the commonly used facial oils. Oleic acid makes up a smaller portion, around 15%.
The high linoleic acid content is the strongest argument for rosehip oil for acne-prone and combination skin. Research consistently shows that sebum from acne-prone skin is relatively deficient in linoleic acid compared to oleic acid. Topical linoleic acid application can help address this imbalance, and studies (including Letawe et al., 1998) have shown reduction in comedone size with topical linoleic acid.
Rosehip oil also contains natural carotenoids and a significant amount of trans-retinoic acid (vitamin A acid), though the concentration is low (approximately 0.003-0.3%). This retinoid precursor content likely contributes to rosehip oil’s evidence for improving skin texture, fine lines, and scars over time. A randomised controlled study published in the Journal of Cosmetic Dermatology in 2015 found significant improvements in fine lines, skin brightness, and overall appearance with rosehip oil applied twice daily for eight weeks.
The limitation of rosehip oil is its instability. The high polyunsaturated fatty acid content makes it prone to oxidation, especially linolenic acid with its three double bonds. Oxidised rosehip oil has lost its beneficial activity and may irritate skin. Store in the refrigerator after opening and discard if it develops a rancid smell or darkens noticeably. Raspberry Seed Oil has a comparable high-polyunsaturated profile with additional natural antioxidants that provide slightly better stability alongside similar skin benefits for oily and combination skin.
Argan oil: the balanced, stable option
Argan oil (Argania spinosa kernel oil) comes from the kernels of the argan tree, native to Morocco. It has a golden colour, a slightly nutty scent, and a more stable composition than rosehip.
The fatty acid profile is approximately 42-49% oleic acid, 30-35% linoleic acid, and smaller amounts of other fatty acids. It is more balanced between oleic and linoleic than rosehip oil, without the high alpha-linolenic content that makes rosehip prone to rapid oxidation.
Argan oil is also distinctively rich in tocopherols (vitamin E), with some of the highest tocopherol content of any cosmetic oil. This provides significant antioxidant protection both within the oil (improving stability) and on the skin when applied. The sterols in argan oil (schottenol and spinasterol, unusual sterols not found in other plant oils) have demonstrated anti-inflammatory and skin moisture-supporting effects in research.
The oleic acid-dominant profile makes argan better suited to dry and mature skin than to oily or acne-prone skin. It provides excellent emollient effect, softening and conditioning the skin surface, and the higher oleic acid content creates a slightly richer feel on skin than rosehip. For winter skin care or for mature skin with reduced sebum production, argan provides the richer conditioning that rosehip cannot.
HOIA’s Organic Argan Oil is used both as a facial oil and a hair treatment, reflecting argan’s versatility as both a skin emollient and a hair cuticle conditioner. Its stability at room temperature makes it more practical for everyday use than the refrigerator-dependent rosehip.
Side by side comparison
Oily and acne-prone skin: rosehip oil (or raspberry seed oil) is the better choice, due to high linoleic acid that addresses sebum imbalance and lighter texture. Argan is borderline; it is less likely to congest than very high-oleic oils but is not as targeted for this skin type.
Dry and mature skin: argan oil is the better choice, with richer emollient properties, vitamin E for antioxidant protection, and better moisture retention for skin with reduced sebum production.
Combination skin: either can work. Rosehip on oilier zones, argan on drier zones, or alternating them seasonally (lighter rosehip in summer, richer argan in winter) is a practical approach.
Sensitive skin: both are generally well-tolerated, but rosehip’s trans-retinoic acid content can occasionally cause sensitivity in people who react to retinoids. Argan is less likely to cause any irritation.
Hyperpigmentation and skin texture: rosehip has stronger evidence for these specific concerns through its linoleic acid and natural retinoid content. Argan contributes through antioxidant protection rather than direct pigmentation or texture mechanisms.
The choice is a practical one based on your skin type and concern. Both are genuinely useful oils with real evidence behind them.
