What Is Rosehip Oil?
Rosehip oil is extracted from the seeds of the rosehip fruit — the small, red berry that forms after a rose flower blooms. The variety most prized in skincare, Rosa canina (also known as dog rose), grows wild across Chile, Argentina, and parts of Europe. The seeds are tiny and oil-rich, packed with essential fatty acids, antioxidants, and naturally occurring vitamin A.
Unlike many plant oils, rosehip oil is a dry oil — it absorbs quickly into skin without leaving a greasy residue, making it suitable for all skin types including oily and combination skin.
Why the Extraction Method Matters
This is the single most important factor when choosing a rosehip oil.
Cold-pressed means the oil is extracted mechanically, using pressure and no heat. This preserves the full fatty acid profile, including the linoleic acid, alpha-linolenic acid, and vitamin A compounds that make rosehip oil effective for skin.
Solvent-extracted (often listed as "hexane-extracted") uses chemical solvents to maximise yield. This is cheaper to produce but strips out many of the beneficial compounds. You'll often see these products priced lower — there's a reason for that.
Refined rosehip oil has been heat-treated and deodorised after extraction. It may look cleaner and smell less "earthy" than cold-pressed oil, but the refining process degrades the very ingredients that make rosehip oil beneficial for skin.
What to look for on the label: "cold-pressed," "unrefined," or "virgin." If the label doesn't say, assume it's refined.
What to Look for When Buying Rosehip Oil in the UK
1. Certified Organic
In the UK, look for NATRUE certification. It's one of the most rigorous international certifications for organic and natural cosmetics and indicates that:
• The rosehips were grown without synthetic pesticides or herbicides
• The extraction process meets organic standards
• No synthetic additives, preservatives, or petrochemicals were used
"Natural" without certification is a marketing claim. "Certified organic" is a verified standard.
2. Cold-Pressed and Unrefined
As outlined above — this protects the fatty acid profile and vitamin A content. The oil should have a slightly amber to golden-orange colour and a faint, earthy scent. Clear, odourless rosehip oil has almost certainly been refined.
3. Single-Ingredient or Minimal Formula
Pure rosehip oil should have one ingredient: Rosa canina seed oil (or Rosa rubiginosa seed oil — both are true rosehip). Some products dilute with cheaper carrier oils like sunflower or rice bran oil. Check the full ingredient list.
4. Dark Glass Packaging
Rosehip oil oxidises when exposed to light. It should be packaged in a dark amber or violet glass bottle, not clear plastic or clear glass.
5. Traceability
The best rosehip oil producers can tell you exactly where their rosehips were sourced. Chilean wild-harvested rosehip is considered the gold standard — the unique climate of the Chilean Andes produces a particularly nutrient-dense fruit.
The Science: What Makes Rosehip Oil Work
Rosehip seed oil is one of the richest plant sources of polyunsaturated fatty acids, particularly:
• Linoleic acid (Omega-6): Approximately 44–50% of the oil. Linoleic acid is essential for maintaining the skin's barrier function. Research has consistently shown that skin prone to acne, sensitivity, and premature ageing is often low in linoleic acid. Applying it topically helps restore barrier integrity and reduces transepidermal water loss.
• Alpha-linolenic acid (Omega-3): Approximately 30–35% of the oil. An anti-inflammatory fatty acid that helps calm reactive and sensitive skin.
• Naturally occurring vitamin A (trans-retinoic acid): Rosehip oil contains small amounts of retinoic acid — the active form of vitamin A — without the irritation associated with synthetic retinol. This contributes to its effectiveness for fine lines and uneven skin tone.
• Vitamin C and antioxidants: The rosehip fruit itself is extremely high in vitamin C. While much of this is in the flesh rather than the seed, the oil contains a range of antioxidant compounds including tocopherols (vitamin E) and carotenoids that help protect against oxidative stress.
A study published in Clinical Interventions in Aging found that participants using rosehip oil showed significant improvements in skin moisture, elasticity, and the appearance of fine lines over an eight-week period compared to a control group.
What Rosehip Oil Can (and Can't) Do for Your Skin
What it does well:
• Brightens uneven skin tone and hyperpigmentation. The combination of vitamin A and antioxidants helps fade post-inflammatory marks, sun spots, and discolouration over consistent use.
• Reduces the appearance of scars. Rosehip oil is a long-standing natural option, recommended by some dermatologists and midwives to help with the appearance of post-surgical scars, stretch marks, and acne scarring. The fatty acids support the skin's natural cell renewal process.
• Hydrates without blocking pores. As a dry, non-comedogenic oil, it absorbs fully and supports skin moisture without contributing to congestion.
• Softens fine lines over time. The naturally occurring vitamin A and linoleic acid improve skin texture and firmness with consistent daily use.
• Calms sensitive and reactive skin. Anti-inflammatory omega-3 fatty acids make it well-suited for rosacea-prone and easily irritated skin.
What it can't do:
• Replace a broad-spectrum SPF (always wear sunscreen over your rosehip oil in the morning)
• Work overnight — results from consistent use typically begin to show at 4–8 weeks
• Replace prescribed retinoids for severe acne or advanced skin ageing
How to Use Rosehip Oil
Morning: 3–4 drops pressed gently into clean skin after serum, before SPF. The oil absorbs in under a minute.
Evening: 4–5 drops after serum as the final step in your routine. Night-time use maximises the vitamin A benefit as your skin's regeneration processes are most active during sleep.
Targeted use: For scars and hyperpigmentation, apply directly to the area twice daily with a fingertip.
With other actives: Rosehip oil is generally well-tolerated alongside vitamin C serums and niacinamide. If using a prescription retinoid, use rosehip oil on alternating nights rather than layered on top.
What to Avoid
• Rosehip oil in water-based formulas: If rosehip appears far down an ingredient list in a lotion or cream, the concentration is too low to be effective. You want it as the lead or sole ingredient.
• Fragrance-added rosehip products: Added fragrance in a face oil increases sensitivity risk for no skin benefit.
• Plastic packaging with no UV protection: The oil degrades rapidly. Dark glass is non-negotiable.
• Vague sourcing claims: "Rosehip oil" with no Rosa canina or Rosa rubiginosa INCI name could be a lower-grade variety.

Frequently Asked Questions
Is rosehip oil good for oily skin?
Yes. Rosehip oil is high in linoleic acid, which has been shown to help regulate sebum production in oily skin. Its lightweight, dry-oil texture absorbs completely without leaving residue. Many people with oily skin find it actually improves their skin's balance over time.
Can I use rosehip oil every day?
Yes — rosehip oil is gentle enough for twice-daily use. For best results, use it morning and evening consistently for at least four to six weeks.
Does rosehip oil clog pores?
No. Rosehip oil is considered non-comedogenic. Its high linoleic acid content actually helps reduce the likelihood of congestion compared to oils high in oleic acid like coconut oil.
Can I use rosehip oil if I'm pregnant?
Rosehip oil doesn't contain synthetic retinol — the ingredient behind most pregnancy-related caution around retinol products — which is part of why it's commonly used during pregnancy, including to help support skin elasticity and the appearance of stretch marks on the abdomen, hips, and breasts. It hasn't been specifically studied for pregnancy safety, though, so as with any new skincare product, it's worth checking with your GP or midwife first.
How long does it take for rosehip oil to work?
Most people begin to notice improvements in skin texture and hydration within two to four weeks of consistent use. Visible improvement in hyperpigmentation, scars, and fine lines typically takes six to eight weeks.
What's the difference between rosehip oil and rosehip seed oil?
They're the same thing. "Rosehip seed oil" and "rosehip oil" both refer to the oil extracted from the seeds inside the rosehip fruit. Some brands use one term, some use the other.
