Grapeseed Oil: Comedogenic Rating & Ingredient Analysis
Grapeseed oil is a light, dry-touch facial oil pressed from the seeds left over from winemaking, and it is a favourite for oily and combination skin that wants the conditioning of an oil without a heavy feel. It is high in linoleic acid and carries natural antioxidants including vitamin E and polyphenols, giving it both barrier-supporting and free-radical-fighting value. Its texture is notably light, absorbing quickly and leaving little residue, and its low comedogenic rating makes it one of the more blemish-friendly oils. It is an affordable, unfussy option for people who find richer oils too greasy.

Where this number comes from
No one has published a comedogenic rating for this ingredient. Fulton's 1989 table tested about 250 raw materials and this was not among them, and we found no later study measuring it. The figure shown is our own reasoning from the ingredient's chemistry and how it is used — treat it as an estimate, not a measurement.
Fulton read his own scale as 0-1 not significant, 2-3 borderline, 4-5 positive. The assay is the rabbit ear at 10% dilution, which the paper itself calls extremely sensitive and not fully predictive of human skin. Ratings describe the raw ingredient; concentration and formulation change real-world behaviour.
Caution profile
The four published fields on this page, on one 0–5 scale. Further from the centre means more care is needed — never that the ingredient is worse.
Derived, not measured: pore-clogging is the published comedogenic rating; irritation maps low/moderate/high to 1/3/5; pregnancy maps safe/caution/avoid to 0/3/5; skin-type limits is how many of the seven skin types this entry does NOT list. Every input is printed in words in the quick-facts card above.

What is it?
The oil is predominantly linoleic acid, one of the highest among common cosmetic oils, along with smaller amounts of oleic acid, vitamin E and grape-derived polyphenols with antioxidant activity. The high linoleic content explains both its light texture and its suitability for acne-prone skin, which often has sebum low in linoleic acid. The antioxidant polyphenols add a defensive benefit against environmental stress. Because it is highly polyunsaturated, grapeseed oil oxidises comparatively quickly, so buying smaller bottles, storing them cool and dark, and using them within a few months keeps the oil fresh and effective.
Benefits
Light, fast-absorbing texture
Grapeseed oil feels notably light and dry-touch, sinking in quickly without a greasy film, which makes it appealing for oily and combination skin that dislikes heavy oils.
High in linoleic acid
Its linoleic-rich profile supports the skin barrier and suits acne-prone skin, whose natural sebum is often deficient in this fatty acid.
Antioxidant polyphenols
Along with vitamin E, its grape-derived polyphenols provide antioxidant defence, helping protect the skin surface from free-radical stress caused by sun and pollution.
Low pore-clogging risk
Its low comedogenic rating makes it one of the more blemish-friendly facial oils, so it conditions without the congestion risk of heavier, oleic-dominant options.
How to use
Use grapeseed oil at night as a lightweight final step, pressing a few drops into damp skin, or mix a drop into a gel or lotion moisturiser for oily skin that still wants a touch of nourishment. Its quick absorption suits daytime use under makeup for some people too, though patch testing your routine is wise. Because it oxidises fairly fast, buy smaller quantities and store them cool and away from light. It pairs well with niacinamide for oil-prone skin and with vitamin E to bolster its antioxidant content.
Side effects
Grapeseed oil is gentle and low-risk, so irritation and clogging are both uncommon. Its main practical drawback is a relatively short shelf life: being high in polyunsaturated fats, it can oxidise and turn rancid faster than more saturated oils, at which point it is less beneficial and best discarded. True allergy is rare but possible, so patch test a new bottle.
Who should avoid it
Very few people need to avoid grapeseed oil, and its light feel and low comedogenic rating make it well suited to oily and acne-prone skin. Anyone with a specific grape or seed sensitivity should patch test. Used on the skin during pregnancy it is regarded as safe, so shelf life, not safety, is the thing to keep an eye on.

Frequently asked questions
Is grapeseed oil good for oily skin?
Yes. It is one of the lighter facial oils, absorbing quickly with little residue, and its high linoleic acid and low comedogenic rating make it well suited to oily and combination skin.
Does grapeseed oil clog pores?
It has a low comedogenic rating, so it is unlikely to clog pores for most people, which is why it is often recommended for acne-prone skin over heavier, oleic-heavy oils.
Is grapeseed oil an antioxidant?
It contains natural vitamin E and grape-derived polyphenols that offer antioxidant activity, helping defend the skin surface against free-radical stress, alongside its barrier-supporting linoleic acid.
Does grapeseed oil go off quickly?
It is high in polyunsaturated fats, so it oxidises faster than more saturated oils. Buy smaller bottles, store them cool and dark, and replace the oil if it develops a sharp, rancid smell.
