Rosehip oil: does it really work? What the data says

People looking for this oil have usually already read that it works miracles and want to know whether that is true. The short answer: yes, but for specific things. The strongest evidence concerns the appearance of scars, softness, and an even complexion; for established wrinkles, the result is much more limited than the packaging suggests.

In summary, before the details: rosehip oil has clinical studies supporting its use for post-surgical scars and a pilot study on texture and sun spots. It is an excellent emollient and a good ally for improving skin texture. It is not a retinoid, it does not fill deep lines, and it does not replace sun protection.

What the studies say

The literature on rosehip is less extensive than marketing would have you believe, but it is not empty. It is worth examining to understand what you can really count on.

Scars: the strongest evidence

The most frequently cited study was conducted at the University Hospital of Gran Canaria on 108 patients who had undergone skin surgery. Seventy-six applied pure rosehip oil twice a day, while thirty-two used nothing; the scars were assessed after six and twelve weeks for redness, color changes, and tissue elevation. The treated group showed greater improvement across all the parameters observed.

That is why rosehip so often appears in post-operative recommendations and products for marks left by blemishes. To be precise: we are talking about the appearance of the scar - its color, softness, and perceived elevation - not its removal.

Texture and sun spots: a pilot study

A more recent study followed 27 volunteers between the ages of 30 and 65 who applied three drops of cold-pressed Rosa canina oil to their faces every day for five weeks, with instrumental measurements taken before and after. Wrinkle depth, UV-induced spots, redness, and texture were measured, with improvements in all four parameters.

The sample is small and the period is short: it is encouraging data, not definitive proof. But it points in the same direction as what is observed in practice - the skin looks more even and less dull before it looks more taut.

The honest picture of the amount of research

A 2023 systematic review searched the main biomedical databases for all studies on rosehip oil applied to scars: it found twenty and considered only two methodologically sound. The authors' conclusion is balanced: the mechanism of action is plausible, the safety profile is good, and the available results are positive, but larger studies are needed. This is exactly the right position to take on this ingredient.

Be careful not to confuse oral use with skin application

Several articles on the anti-aging effectiveness of rosehip cite a 2015 study published in Clinical Interventions in Aging: 34 people, eight weeks, improvements in crow's feet, hydration, and elasticity. It is a serious study, but it concerns a powder taken orally, not an oil applied to the face. These are two different things, and attributing the results of a supplement to a cream is the most common shortcut in communication about this ingredient.

What it is and why it works

Rosehip oil is extracted from the seeds of Rosa rubiginosa (and related species such as Rosa canina), wild shrubs widespread in the Andean regions of Chile. It is not obtained from the petals but by cold-pressing the seeds contained in the rose hips, a method that preserves micronutrients that are more fragile when exposed to heat.

The composition clearly explains how it behaves on the skin:

• Linoleic acid, approximately 54%: it is the most abundant component and is also one of the building blocks of skin ceramides. Dry and acne-prone skin often has a reduced amount of it in sebum;
• Linolenic acid, approximately 17% (Omega 3) and oleic acid, approximately 16% (Omega 9): they complete the emollient profile and support the lipid component of the skin barrier;
• Carotenoids — beta-carotene, lycopene, lutein — responsible for the amber color and part of the antioxidant activity;
• Vitamins C and E, which counteract free radicals.

In official cosmetic ingredient databases, the functions recognized for this oil are emollient and skin conditioning. It is a modest description, but also its strong point: it reliably leaves the skin soft and comfortable, which is the foundation of any visible improvement.

It is often said that rosehip oil contains trans-retinoic acid, that is, tretinoin. The actual fact is that traces ranging from 0.01% to 0.1% are found: minimal amounts, and in any case tretinoin is a drug, not a cosmetic ingredient. Rosehip oil's effect on skin renewal does exist, but it should be attributed to its fatty acid and carotenoid profile, not to prescription-retinoid activity. Those seeking that effect will find an honest comparison in the in-depth article on retinol.

Wrinkles, dark spots, scars: what is it really for?

The three most frequently asked questions deserve three distinct answers, because reasonable expectations vary greatly.

For hyperpigmentation, one clarification is useful: rosehip oil works on overall complexion and antioxidant protection, but it is not a melanin inhibitor. For a defined, persistent spot, it works well alongside molecules that act on the mechanism, such as azelaic acid or vitamin C, and above all it does not replace sun protection, without which any work on dark spots is undone every day.

How to use it

A few rules, but they make the difference between an oil that works and one that simply sits on the skin without doing anything.

1. Apply at the end, after serum and moisturizer: since it is lipophilic, it seals in what is underneath, whereas applying it first hinders the absorption of water-soluble active ingredients.
2. A few drops are enough: two or three for the entire face, warmed between the palms and gently patted on. Excess product does not penetrate further; it stays on the surface and feels greasy.
3. Evening is best, especially when using pure oil: the texture is not very compatible with makeup or morning sunscreen.
4. It should be stored away from light. It is rich in polyunsaturated fatty acids, so it can go rancid: oil with a pungent smell has lost much of its value and should be replaced.
5. Consistency is key. In the scar study, results were measured after six and twelve weeks, with two applications per day. Using it sporadically for two weeks is not the same treatment.

Pure oil or dermocosmetic formula

Both approaches are valid and meet different needs. Pure oil is the most direct choice for a localized scar or a very dry area. A complete formula, on the other hand, provides active ingredients that the oil alone does not contain in a single application - humectants such as hyaluronic acid, which draws in water, while the oil locks it in: these are two complementary functions, which is why they often coexist in the same formula.

Contraindications and who may benefit less

It is a well-tolerated ingredient, with a good safety profile also demonstrated in clinical studies. A few precautions are still useful.

• Very oily or acne-prone skin: the high linoleic acid content can be beneficial, but the rich texture may feel heavy. It is better to incorporate it into a balanced formula than to use it undiluted over the entire face.
• Open wounds or active lesions: treat the scar once the wound has closed. For a fresh wound, follow your doctor's advice.
• Allergy to the Rosaceae family: rare, but a patch test on the crook of the elbow before applying it to the face remains the simplest precaution.
• Rancid oil: this is the most common cause of irritation attributed to rosehip oil. It is not the ingredient, but improper storage.

Rosehip in LeLang formulas

In our formulas, we never use the oil on its own: we include it where its lipid profile complements active ingredients that work on other fronts.

Elyx Performance Serum

Here, rosehip oil works with snail mucin and hyaluronic acid. It is the preferred choice for those who want to target uneven skin tone, post-acne marks, and firmness.

5 Complex Night

At night, skin metabolism accelerates. This oil combines rosehip with prickly pear oil and rice bran oil, creating an antioxidant booster that counteracts nighttime dehydration.

On the rosehip oil ingredient page, you will find the complete list of formulas containing it. You can also find LeLang products at partner pharmacies and parapharmacies throughout Italy.

Frequently asked questions

Does rosehip oil really work?

Yes, for specific goals. Clinical studies support its ability to improve the appearance of scars, and a pilot study examined texture, redness, and sun spots; it is a reliable emollient for dry and dehydrated skin. Expectations should be adjusted for deep wrinkles, where it has little effect. The available research is positive but still limited in the number of high-quality studies.

Is it effective against wrinkles?

For fine lines and dehydration lines, yes: well-nourished skin reflects light better, and micro-lines appear less pronounced, with visible improvement in four to six weeks. For deep-set lines already structured in the dermis, its contribution is modest because they depend on collagen loss: peptides and retinoids work better there.

What does rosehip oil do for the face?

It replenishes lipids similar to those found in the skin, reducing water evaporation and restoring softness; it provides carotenoids and vitamins C and E with antioxidant action; and it supports tissue remodeling in marked areas. The perceived result is softer, more even, less dull skin.

Does it help with facial spots?

It helps with the overall evenness of skin tone and provides antioxidant support, while the pilot study mentioned above found a reduction in UV-induced spots. However, for a defined and persistent spot, it is best combined with ingredients that act on melanin and, above all, daily sun protection.

How long does it take to see results?

For comfort and softness, a few days. For skin texture and radiance, four to six weeks. For scars, the studies measured changes at six and twelve weeks with two daily applications: this is the realistic benchmark, and it is also why many trials "do not work" — they are stopped too soon.

Does it have side effects?

In the studies, the tolerability profile was good and reactions were rare. The two situations that cause problems are the use of rancid oil, recognizable by its pungent smell, and the generous application of pure oil to very oily skin, where the texture may feel occlusive. Neither is caused by the ingredient itself.

Can it be used together with hyaluronic acid?

Yes, and it is in fact the most sensible pairing: hyaluronic acid draws in water, while the oil retains it and prevents it from evaporating. The order matters — first apply the hyaluronic acid serum to still slightly damp skin, then the oil or cream containing it.

Can it be used during pregnancy?

For topical use, it is one of the ingredients that continues to be used without particular reservations, and it is one of the most commonly chosen for stretch marks precisely at this stage. The traces of trans-retinoic acid present in the oil are in the order of hundredths of a percentage point and are not comparable to a cosmetic or pharmaceutical retinoid. For oral intake of rosehip-based supplements, however, the reference remains the gynecologist.
