Grapeseed Oil: Evidence, Safety and How It Is Used
Grapeseed oil is a carrier oil, not an essential oil or grape seed extract: what we found for skin, what we did not, and basic safety points to check first.

Safety first. Natural products can cause side effects and interact with medicines. Read essential oil safety before you use anything on this page.
Safety first: little has been tested, so patch test and go slowly. We did not find allergy case reports for grapeseed oil in the abstracts we saw, which is not proof that none exist. Poison Control says allergy to an oil is possible, rash is the most common reaction, and you should stop use and wash it off if a rash appears. [1] If anyone swallows an oil and you are worried, call Poison Help at 1-800-222-1222 or your local emergency number. [1]
Grapeseed oil is a carrier oil, which is a plain plant oil. It is not an essential oil, and it is not grape seed extract. This page keeps apart lab findings, human trials, and the route (skin, or eaten).
What grapeseed oil is
Grapeseed oil is a fatty oil from the seeds of the wine grape, Vitis vinifera, which GBIF lists as an accepted name in the grape family, Vitaceae. [3] A 2023 review says most research looks at its fatty acids, tocopherols (vitamin E compounds) and plant sterols, and that results are hard to compare because oils are made by different extraction methods and studies use different units. [4] In seeds from 12 grape varieties, linoleic acid made up 53.7 to 67.1 percent of the fatty acids and oleic acid 13.8 to 27.3 percent, and amounts differed more between varieties than between ripening stages. [8] That is the seed, not a bottle of oil.Grape seed extract is a different product: a supplement made mainly of proanthocyanidins, studied by mouth for blood pressure and cholesterol. NCCIH's page covers the extract and does not mention grape seed oil. [9] See grape seed extract. Results for the extract do not apply to the oil.
A carrier oil is used to dilute an essential oil before it goes on skin. The National Cancer Institute describes aromatherapy massage as essential oils diluted in a carrier oil. [2] Poison Control says dilution in a carrier oil is the best way to avoid a bad reaction from direct skin contact with a potent essential oil. [1] A carrier does not make an unsuitable essential oil suitable. See carrier oils explained. We found no grapeseed-specific dilution figure. Charts differ between sources: see why dilution charts differ. This is information, not a prescription.
Safety by group
- Skin and allergy: see the warning above. Not described is not proof of none. See patch testing and stopping a reaction and skin reactions, allergy and sensitization.
- Sun: a 2025 scoping review of seed oils named grape oil among oils that absorbed ultraviolet-B light in laboratory tests, and said safety and phototoxicity assessments were insufficient. [7] That is a lab measurement, not a reason to use an oil as sunscreen. We found no source on sun sensitivity of grapeseed oil on skin.
- Freshness: grape seed fatty acids are mostly polyunsaturated. [8] In general such oils oxidize more easily, but we found no source that measured how fast grapeseed oil goes rancid or what a rancid oil does to skin. See storing oils and shelf life.
- Pets (cats, dogs, birds): not described in the sources we read. See essential oils and pets.
- Pregnancy and breastfeeding: not described for the oil. NCCIH says little is known about the extract in pregnancy and breastfeeding. [9] That is the extract, not the oil. See pregnancy and breastfeeding.
- Babies and children: Poison Control says children's thin skin and immature livers may make them more susceptible to toxic effects of oils in general. [1] A trial of a grape-seed-oil-containing gel included children aged 2 to 14 (see below), but it was a mixed product. [5] Ask a clinician. See around babies and children.
- Seizures and breathing: not described for grapeseed oil in the sources we read.
- Swallowing: Poison Control says swallowing some essential oils is poisonous and swallowed oil can be breathed in, causing pneumonia. [1] It does not discuss grapeseed oil. See what poison centers say.
- Medicines: not described for the oil. NCCIH says people taking any medicine should talk with a provider before taking the extract. [9]
What research shows
| Question | What the source found | Strength of evidence | Route, form and who was studied |
|---|---|---|---|
| Atopic dermatitis (eczema) in children | In a randomized, self-controlled trial of 57 children aged 2 to 14, a gel containing grape seed oil plus hyaluronic acid, glycerol, calendula, aloe and a peptide was applied for 10 days. Redness and water loss fell and hydration rose on the treated forearm, compared with the untreated forearm; no adverse effects were reported. [5] | Insufficient evidence for the oil | Mixed product on skin; the oil was one of several ingredients; blinding not stated in the abstract |
| Wrinkles | A 2024 study tested an engineered grapeseed oil emulsion and reports better skin hydration and fewer facial lines after 28 days. The abstract we read does not say how many people took part. [6] | Insufficient evidence | Special emulsion made for the study, not plain oil |
| Sun protection | Grape oil was among oils that absorbed UVB in lab tests; the review says safety evidence is insufficient. [7] | Lab or animal only | Laboratory measurements |
| Antioxidant and other health claims | A review describes the oil's tocopherols and sterols and calls for better extraction methods. [4] | Lab or animal only | Review of compositions |
Limits: Proper evidence not found in the sources we read for plain grapeseed oil improving eczema, wrinkles, acne, hair or wound healing in people. The trials we found used mixed products, were short, and the oil cannot be credited with the results.
How it is used and what the sources say about quality
- Grapeseed oil is used on skin, as a carrier oil in massage blends, and as a food oil. [2][4] Some aromatherapy trials have used it as part of a carrier or comparison; see essential oils for hair growth and scalp.
- A review notes that extraction methods vary, so oils from different makers may not match. [4] See reading an essential oil label and purity and adulteration.
- Store as the label says; see storing oils.

Uses studied and safety checks for Grapeseed Oil
Read the safety checks first. Each card says whether a finding comes from people or only from the lab, which way the oil was used (scent, on skin or swallowed) and how strong the evidence is. A finding for one way of using an oil does not carry over to another.
Check before you use (4)
- Skin allergy and irritation. We did not find allergy or contact dermatitis case reports for grapeseed oil in the Europe PMC abstracts we saw (not proof that none exist). Poison Control says allergy to an oil is possible; stop use and wash off if a rash appears.
- Rancidity and quality. Grape seed fatty acids are mostly polyunsaturated (linoleic acid 53.7 to 67.1 percent in seeds of 12 grape varieties), which in general makes an oil easier to oxidize; amounts varied by variety. We found no source in this round that measures how fast grapeseed oil goes rancid or what a rancid oil does to skin.
- Cats, dogs, pregnancy, babies, seizures, medicines. The sources we read do not describe grapeseed oil for pets, pregnancy or breastfeeding, babies, seizure disorders or medicine interactions. NCCIH says little is known about grape seed extract in pregnancy and breastfeeding; that is the extract, not the oil. Poison Control says children's thin skin and immature livers may make them more vulnerable to oils in general.
- Swallowing and aspiration. Poison Control says swallowing some essential oils is poisonous and swallowed oil can be breathed in, causing pneumonia. It does not discuss grapeseed oil. If anyone swallows an oil in a worrying way, call a poison center (US 1-800-222-1222) or your local emergency number.
Grapeseed oil on skin (small trials of mixed products)
Not enough evidenceIn a randomized trial of 57 children with atopic dermatitis, a gel that contained grape seed oil together with hyaluronic acid, glycerol, calendula, aloe and a peptide was applied for 10 days; skin redness, water loss and hydration measures improved on the treated forearm, with no adverse effects reported. A separate 2024 study tested an engineered grapeseed oil emulsion for wrinkles; the abstract does not say how many people took part.
Supplements: No trial of plain grapeseed oil on skin was found in the sources we read.
What grapeseed oil is (a carrier oil, not an essential oil)
Established roleGrapeseed oil is a fatty oil made from the seeds of the wine grape. A review says grape seed fatty acids are mostly linoleic acid, with some oleic acid, plus tocopherols and plant sterols. It is used on skin and as a carrier oil to dilute essential oils.
Supplements: Fatty oil.
Not the same as grape seed extract
Not enough evidenceGrape seed extract is a supplement made mainly of proanthocyanidins and has been studied by mouth for blood pressure and cholesterol. NCCIH's page covers the extract and does not mention grape seed oil. Results for the extract do not apply to the oil.
Supplements: Different product.
Sun protection claims (lab)
Lab or animal research onlyA scoping review of seed oils named grape oil among oils that absorbed ultraviolet-B light in laboratory tests, and said safety and phototoxicity assessments were insufficient. Oils on their own gave low sun protection factors, and the review gives no grape-specific safety data. It is not a replacement for sunscreen.
Supplements: Lab only; do not treat as sunscreen.
Frequently asked questions
Is grapeseed oil an essential oil?
No. It is a fatty plant oil from grape seeds, used on skin and as a carrier oil. [4][2]
Is it the same as grape seed extract?
No. The extract is a supplement mainly studied by mouth. NCCIH's extract page does not mention the oil. [9]
Does grapeseed oil work for skin?
Plain grapeseed oil has not been shown to treat skin conditions in the sources we read. One trial used a gel with several ingredients including the oil. [5]
Is it safe for cats, dogs, babies or pregnancy?
The sources we read do not describe grapeseed oil for pets or pregnancy. Poison Control says children's thin skin and immature livers may make them more susceptible to toxic effects of oils. [1] Ask a clinician or vet.
Should I swallow it?
No advice to swallow cosmetic oils is given. Poison Control says to call a poison center (US 1-800-222-1222) if an oil has been swallowed and you are worried. [1]
