Few carrier oils have earned the kind of sustained, global attention that rosehip oil has. It sits at the intersection of two powerful consumer trends — the demand for natural, plant-derived skincare and the appetite for evidence-backed formulation ingredients. For DIY formulators and small skincare businesses, it is one of the most commercially important carrier oils to understand deeply, because it appears in product categories ranging from face serums and night oils to eye creams, scar formulations, and blended facial moisturisers.
This guide is written for formulators. It goes beyond the surface-level "benefits" content that dominates consumer skincare blogs and instead gives you the technical information you need to use rosehip oil correctly: its full fatty acid profile with verified data, comedogenic rating, usage rates by product type, shelf life management, formulation compatibility, three complete recipes, and a direct comparison with its closest functional alternatives.
All rosehip oil referenced in this guide is available in cosmetic grade from The Skin Science Company, with fast 2–3 day dispatch across Australia.
What Is Rosehip Oil?
Rosehip oil — also called rosehip seed oil — is extracted from the seeds of the fruit (hip) of the rose plant, most commonly Rosa canina (dog rose) and Rosa rubiginosa (wild rose). It is produced primarily by cold-pressing the dried seeds, though solvent-extracted and CO₂-extracted versions also exist. Cold-pressed is the standard for cosmetic formulation.
It is important to note that rosehip oil is not the same as rose essential oil (which is steam-distilled from rose petals and is an entirely different ingredient). Rosehip oil has no significant fragrance and is valued entirely for its fatty acid and micronutrient profile, not its scent.
Fatty Acid Profile: The Data That Matters
Rosehip oil's cosmetic properties are almost entirely explained by its fatty acid composition. The following table presents the typical fatty acid profile based on published analytical data.
| Fatty Acid | Type | Typical % in Rosehip Oil | Significance for Skin |
|---|---|---|---|
| Linoleic Acid (C18:2, omega-6) | Polyunsaturated (PUFA) | 44–50% | Supports skin barrier function; associated with sebum regulation; dominant fatty acid |
| Alpha-Linolenic Acid (C18:3, omega-3) | Polyunsaturated (PUFA) | 20–35% | Anti-inflammatory properties; supports skin barrier; essential fatty acid |
| Oleic Acid (C18:1, omega-9) | Monounsaturated (MUFA) | 13–20% | Skin penetration enhancer; contributes to nourishment and softness |
| Palmitic Acid (C16:0) | Saturated | 3–5% | Emollient; contributes to skin barrier |
| Stearic Acid (C18:0) | Saturated | 1–3% | Emollient; contributes to skin barrier |
| Palmitoleic Acid (C16:1) | Monounsaturated | 0.5–2% | Found naturally in sebum; skin-compatible |
Key insight for formulators: Rosehip oil is dominated by polyunsaturated fatty acids (PUFAs), which account for approximately 65–85% of its total fatty acid content. This is what makes it so effective for skin — and also what makes it prone to oxidation. High PUFA content means high instability. This is not a flaw; it is a trade-off that every formulator needs to understand and manage.
Additional Bioactives: Beyond Fatty Acids
Rosehip oil contains several bioactive compounds beyond its fatty acid profile that contribute to its cosmetic properties.
Carotenoids — including beta-carotene and lycopene — give cold-pressed rosehip oil its characteristic deep orange-red colour. These are precursors to vitamin A and are associated with antioxidant activity in the skin.
Tocopherols (Vitamin E) — present at approximately 30–50 mg/100 g in cold-pressed rosehip oil. These contribute to the oil's antioxidant activity and provide some natural protection against oxidation, though not enough to significantly extend shelf life without additional antioxidant support.
Trans-retinoic acid — a small amount of naturally occurring retinoic acid has been detected in some rosehip oil samples, though the concentrations are extremely low and variable. This should not be conflated with pharmaceutical-grade retinoids. Rosehip oil is not a substitute for retinol or tretinoin in a formulation context, and no therapeutic claims should be made on this basis.

Which Skin Types Benefit Most?
Rosehip oil's high linoleic acid content makes it particularly well-suited to skin types that tend to be deficient in linoleic acid — a pattern that has been observed in research on acne-prone and oily skin. This is counterintuitive for many consumers who assume that oily skin should avoid oils, but a linoleic-rich oil like rosehip can be an excellent choice for oily, congestion-prone skin precisely because it does not add to the oleic acid load that can contribute to comedone formation.
For dry and mature skin, rosehip oil is valued for its combination of linoleic and alpha-linolenic acids, which support the skin's lipid barrier, and its carotenoid content, which provides antioxidant support. It is commonly incorporated into formulations targeting uneven skin tone, post-inflammatory hyperpigmentation, and the visible signs of skin ageing — all within a cosmetic-use context.
| Skin Type / Concern | Suitability | Notes |
|---|---|---|
| Oily / acne-prone | Excellent | High linoleic acid; comedogenic rating of 1; lightweight skin feel |
| Dry / dehydrated | Excellent | Supports lipid barrier; blend with richer oils (e.g. avocado, marula) for very dry skin |
| Mature / ageing | Excellent | Carotenoids, tocopherols, and essential fatty acids support skin appearance |
| Sensitive / reactive | Good (patch test recommended) | Generally well-tolerated; some individuals may react to the earthy scent compounds in unrefined oil |
| Normal / combination | Excellent | Versatile; suitable as a daily facial oil or serum base |
| Post-procedure / compromised barrier | Good (use refined) | Refined rosehip preferred to minimise potential irritation from natural scent compounds |
Shelf Life and Oxidation Management
This is the most commonly misunderstood aspect of working with rosehip oil, and it is where many formulators — particularly beginners — run into problems. Rosehip oil oxidises relatively quickly compared to more stable carrier oils like jojoba or argan. An oxidised oil will smell rancid (sharp, crayon-like, or paint-like), darken in colour, and may cause skin irritation. It should never be used in a formulation once it has oxidised.
Practical shelf life management for formulators:
First, always add Vitamin E Oil at 0.5–1% to any formulation containing rosehip oil. Vitamin E (tocopherol) is a fat-soluble antioxidant that donates electrons to free radicals, interrupting the oxidation chain reaction and significantly extending the usable life of high-PUFA oils.
Second, store rosehip oil — and any formulation containing it — in dark, airtight containers away from heat and light. Amber glass bottles are ideal for finished products. Avoid clear packaging.
Third, if you are formulating a product with a high rosehip oil percentage (above 30%), consider adding a rosemary antioxidant extract (ROE) at 0.02–0.1% as a secondary antioxidant alongside vitamin E.
Fourth, when adding rosehip oil to an emulsified product (lotion or cream), add it in the cool-down phase rather than the heated oil phase. This preserves more of its heat-sensitive bioactives and reduces the oxidative stress from prolonged heat exposure.
Rosehip Oil vs. Its Closest Alternatives
Formulators frequently ask how rosehip compares to other high-PUFA facial oils. The following table provides a direct comparison with the most relevant alternatives available from The Skin Science Company.
| Oil | Linoleic % | Oleic % | Comedogenic Rating | Shelf Life | Key Differentiator | SSC Product |
|---|---|---|---|---|---|---|
| Rosehip Oil | 44–50% | 13–20% | 1 | 6–12 months | High carotenoids; iconic facial oil; versatile | Rosehip Oil |
| Bakuchi Oil | ~52% | ~18% | 1 | 12–18 months | Contains bakuchiol — a plant-derived retinol alternative; more stable than rosehip | Bakuchi Oil |
| Pomegranate Seed Oil | ~3% | ~6% | 1 | 12–18 months | Unique punicic acid (omega-5 ) content; antioxidant-rich; more stable than rosehip | Pomegranate Seed Oil |
| Raspberry Seed Oil | ~54% | ~12% | 0–1 | 6–12 months | Very high linoleic acid; natural UV-absorbing properties (not a sunscreen substitute ) | Raspberry Seed Oil |
| Sea Buckthorn Oil | ~35% | ~25% | 1 | 12–24 months | Extremely high carotenoid content; intense orange colour; use at low % (0.5–2% ) | Sea Buckthorn Oil |
| Argan Oil | ~35% | ~45% | 0 | 24–36 months | More oleic-dominant; more stable; better for dry skin; longer shelf life | Argan Oil |

Frequently Asked Questions
These FAQs are structured for Google's FAQ rich result feature. The JSON-LD schema at the top of this post registers them with search engines.
What is the comedogenic rating of rosehip oil?
Rosehip oil has a comedogenic rating of 1, meaning it is considered non-comedogenic and suitable for most skin types including oily and acne-prone skin.
What percentage of rosehip oil should I use in a face serum?
For a face serum, rosehip oil is typically used at 50–100% as a standalone oil serum, or at 20–50% as part of a blended face oil. In emulsified creams and lotions, 2–10% is typical.
Does rosehip oil go rancid quickly?
Yes. Rosehip oil has a relatively short shelf life of 6–12 months due to its high polyunsaturated fatty acid content. Always store in a dark, cool place and add 0.5–1% Vitamin E oil to extend shelf life.
What is the difference between cold-pressed and refined rosehip oil?
Cold-pressed rosehip oil retains its natural deep orange-red colour, characteristic earthy scent, and higher levels of carotenoids and tocopherols. Refined rosehip oil is lighter in colour and scent, making it preferable in formulations where a neutral base is needed.
Can I use rosehip oil on oily or acne-prone skin?
Yes. Rosehip oil's high linoleic acid content (44–50%) makes it particularly well-suited to oily and acne-prone skin. Research suggests that acne-prone skin tends to be deficient in linoleic acid, and topical application of linoleic-rich oils may help support skin balance.
