Early evidence · 3 studies
Rash/Contact Dermatitis
The only relevant clinical evidence involves Vitis vinifera (grape) as one of several active ingredients in a combination medical device (Atopiclair/MAS063D) for atopic dermatitis: one small RCT (n=30) showed significant improvement in itch, EASI score, and affected body area, and a 2018 evidence-based review including a meta-analysis of 4 RCTs confirmed the combination product's efficacy. No studies tested grapeseed oil alone, and the condition studied was atopic dermatitis rather than contact dermatitis specifically.
Evidence for grapeseed in acne is indirect and limited: one small single-blind RCT in healthy male volunteers showed a 2% grape seed extract emulsion significantly reduced skin sebum (a contributor to acne) but did not enroll acne patients or measure acne outcomes, and a separate in vitro study found Vitis vinifera leaf extract (not seed oil) inhibited Cutibacterium (Propionibacterium) acnes growth and biofilms. No clinical trials of grapeseed oil in acne patients were identified.
One small single-blind RCT found that a 2% grape seed extract emulsion significantly reduced cheek skin melanin versus placebo over 8 weeks, and an in vitro study showed Vitis vinifera leaf extract competitively inhibits tyrosinase (IC50 3.84 mg/mL), the key enzyme in melanin production. Critically, neither study tested grapeseed oil itself—the depigmenting polyphenols identified are concentrated in extracts and largely absent from the pressed oil—so direct clinical evidence for grapeseed oil in hyperpigmentation is lacking.
Only one small open-label RCT (n=40) includes grapeseed (Vitis vinifera) seed oil, and only as one of seven ingredients in a nutraceutical adjunct to etanercept; the significant findings were improvements in HDL cholesterol and triglycerides (metabolic syndrome parameters), not psoriasis skin outcomes. No study isolates grapeseed oil's effect on psoriasis lesions, so there is no direct clinical evidence supporting grapeseed oil for treating psoriasis.
The provided results contain no human clinical trials of grapeseed oil for burns or wound healing. The only tangentially relevant study (PMID 37462414) is a preclinical in vivo animal study of Vitis vinifera leaf extract (a different plant part, not seed oil) in a liposomal gel showing wound closure and anti-MRSA effects; the other visible result (PMID 40498644) concerns wound responses in grapevine plant grafting and is irrelevant to human therapeutics.
No direct clinical trials of grapeseed oil for dry skin were found in the retrieved results. The only tangentially relevant evidence is a 2018 evidence-based review whose meta-analysis of 4 RCTs supported a multi-ingredient moisturizer (glycyrrhetinic acid, hyaluronic acid, shea butter, telmesteine, and Vitis vinifera) for atopic dermatitis—efficacy cannot be attributed to the grape-derived component alone; other retrieved results concerned grape viticulture chemistry and plant stem cells, not skin outcomes.
The only retrieved study is a small (N=16) open-label, vehicle-controlled trial of MAS063DP, a multi-ingredient hydrolipidic dressing containing Vitis vinifera (grape) extract alongside glycyrrhetinic acid, telmesteine, and vitamins C and E, tested in partial-thickness wound patients rather than eczema patients. It showed improved skin barrier recovery versus petrolatum, but no study directly evaluates grapeseed oil alone for eczema, so evidence for this pair is indirect and very limited.
The only verifiable retrieved article is a 2022 narrative review on plant-derived phenolic acids (with Vitis vinifera listed as one of several sources) that reports anti-inflammatory and anti-arthritic potential based on preclinical in vitro and animal studies. No clinical trials, RCTs, or systematic reviews specifically evaluating grapeseed oil for joint inflammation were identified in the provided results.
