Type "does rosehip oil work for stretch marks" into Google and you'll get thousands of confident yes-answers — almost none of them citing a single study. We went looking for the actual research, because "engineer-vetted" means we check before we claim, not after.
The honest answer is more useful than the marketing one: the best clinical evidence doesn't test rosehip oil alone. It tests rosehip oil as one ingredient in a multi-active cream, on pregnant women, for prevention rather than removal. That's a narrower claim than most product pages make — and it's still a meaningfully positive one.
• The strongest rosehip-oil evidence is a 2013 randomized trial testing a cream containing rosehip oil, Centella asiatica, and vitamin E — not rosehip oil alone.
• In that trial, previously unmarked skin developed new stretch marks in only 5.6% of the treated group versus 35% of the control group.
• Existing marks worsened in 17.8% of the control group but only 6.3% of the treated group over the study period.
• For established, mature (white/silvery) stretch marks, prescription tretinoin and fractional lasers have stronger clinical evidence than any topical oil, rosehip included.
What Causes Stretch Marks in the First Place?
Stretch marks (striae distensae) form when skin is stretched faster than the dermis can rebuild collagen and elastin to keep up — typically during pregnancy, puberty growth spurts, rapid weight change, or muscle gain. The tearing happens in the dermis, the structural layer beneath the surface, which is why stretch marks are a texture and pigment change rather than a surface wound.
New marks usually start red, purple, or dark brown depending on skin tone, because the area is still inflamed and vascularized. Over months to years they fade to a lighter, flatter, silvery-white scar as the blood supply reduces and collagen remodels — which matters for what any topical product, oil included, can realistically do at each stage.
Does Rosehip Oil Actually Help With Stretch Marks?
The most rigorous trial on this exact question is a 2013 randomized, double-blind, placebo-controlled study published in the International Journal of Cosmetic Science. Pregnant women used a cream containing rosehip oil alongside hydroxyprolisilane-C, Centella asiatica triterpenes, and vitamin E — so the result describes that formula, not rosehip oil in isolation.
The findings were genuinely positive on prevention and severity, even though overall incidence wasn't significantly different between groups. Among women with no prior stretch marks, only 5.6% of the treated group developed new ones versus 35% of the control group (P = 0.031). Among women who already had marks, severity worsened in 17.8% of the control group but just 6.3% of the treated group. That's a real, statistically significant effect — on a combination formula, applied consistently, starting before or early in pregnancy.
How Is Rosehip Oil Supposed to Work on Stretch Marks?
Rosehip oil is one of the few plant oils that carries naturally occurring trans-retinoic acid — a form of vitamin A — alongside vitamin C and essential fatty acids. Retinoic acid is the active class dermatologists reach for first when treating stretch marks with prescription tretinoin, because it's linked to collagen synthesis and skin cell turnover. Vitamin C is a cofactor in that same collagen-building process, and the linoleic and alpha-linolenic fatty acids support the skin barrier while the area remodels.
Our own Rosehip Face Oil blends Rosa canina fruit oil with hemp seed oil and squalane specifically so those actives absorb rather than sit on the surface — the same absorption logic that matters whether you're using it on your face or on stretch-mark-prone skin elsewhere on the body. That's a plausible mechanism, not a guarantee: no published trial has isolated rosehip oil's vitamin A/C content and tested it alone against stretch marks specifically.
Does It Work Better on New Marks Than Old Ones?
Logically, yes — and the mechanism explains why. New (red or purple) stretch marks are still inflamed, vascularized, and actively remodeling collagen, which is exactly the window where a retinoic-acid-and-vitamin-C oil has biology to act on. Mature white stretch marks are largely finished scar tissue with a much thinner blood supply, so there's simply less active process left for any topical product to influence.
This is consistent with how the 2013 trial was designed: it measured prevention and early-severity control during pregnancy, not reversal of long-established marks. No study we found tested rosehip oil specifically on old, white striae — treat "it might fade my years-old silvery marks" as the unproven claim it is, not the proven one.
How Do You Use Rosehip Oil for Stretch Marks?
- Cleanse and pat the area damp. Slightly damp skin helps a lightweight oil spread evenly and absorb rather than sit on the surface.
- Apply a few drops directly to the stretch-mark-prone area. Newer, actively-forming marks are the priority — this is where the evidence is strongest.
- Massage in gently until absorbed, using circular motions rather than dragging, twice daily (morning and night is the pattern the clinical trial followed).
- Stay consistent for at least 8-12 weeks before judging results — collagen remodeling is slow, and the trial that found a real effect ran across most of a pregnancy, not a few weeks.

If you want faster or stronger results than any oil can promise, a dermatologist has options with better evidence behind them. A 2022 narrative review of striae treatments found that 0.05% prescription tretinoin cream showed improvements up to 47%, and non-ablative fractional lasers showed 50-75% improvement in striae lesions — both meaningfully ahead of any topical oil studied to date, including rosehip. The same review's overall conclusion is worth repeating honestly: "no fully effective treatment has emerged" for stretch marks, oil, prescription, or laser.
Consult a board-certified dermatologist if your stretch marks are causing you distress, if you want to explore tretinoin or laser options, or if any marked area shows unusual pain, rapid change, or signs of infection — those aren't things a face oil is meant to address. If you're pregnant or breastfeeding, check with your doctor before starting any new topical, including rosehip oil, and patch-test on your inner wrist for 24 hours first.
Frequently Asked Questions
Can rosehip oil remove stretch marks completely?
No. No topical product — oil, cream, or otherwise — has been shown to fully remove stretch marks, especially once they've matured to the white/silvery stage. The best evidence for rosehip-containing formulas is for reducing new-mark severity and slowing progression, not erasing existing marks.
How long before I'd see a difference?
Give it at least 8-12 weeks of consistent, twice-daily use before judging. The clinical trial with a measurable effect ran across most of a pregnancy — collagen remodeling is a slow process, not a two-week one.
Is rosehip oil safe to use on stretch marks during pregnancy?
The main supporting study was conducted in pregnant women, which is reassuring, but you should still check with your doctor before adding any new topical during pregnancy or while breastfeeding, and patch-test on your inner wrist for 24 hours first.
Can I use rosehip oil with other stretch-mark creams or a dermatologist's tretinoin?
Generally yes as a layering step — apply the lighter oil first and let it absorb before a heavier cream. If you're using prescription tretinoin, ask your dermatologist how to sequence it, since retinoids can already be drying and layering actives without guidance can irritate healing skin.
