What it is
A botanical extract obtained from the stems of grapevines, rich in polyphenolic compounds such as resveratrol, flavonoids, and tannins. It is a byproduct of winemaking, making it a sustainable ingredient.
How it works
The polyphenols in grape stem extract neutralize free radicals (unstable molecules that can damage skin cells), reducing oxidative stress. It also has mild anti-inflammatory properties, which can help calm redness and irritation. In formulations, it acts as an antioxidant to help preserve the product and protect the skin.
Pros
Gentle antioxidant
Provides a mild, natural way to defend skin against daily pollution and UV stress without irritation, making it suitable for sensitive skin types.
Sustainable sourcing
Made from grape stems, a byproduct of winemaking, this ingredient supports eco-friendly practices by repurposing agricultural waste.
Cons and cautions
Limited research
Most evidence comes from lab studies; there are few human clinical trials confirming its benefits on skin when applied in a cream or serum.
Potential allergen
Though rare, people with grape allergies may experience a reaction, so patch testing is advised if you have known sensitivities.
Best for
- Anyone looking for gentle antioxidant protection
- People with normal to combination skin who want a natural, soothing ingredient
Use caution if
- Individuals with a known allergy to grapes or grape-derived ingredients
Usage tips
Safety summary
Grape stem extract is considered safe for topical use with a low risk of irritation. Allergic reactions are rare but possible in individuals with grape allergies. As with any new ingredient, a patch test is recommended.
Research notes
In vitro studies show grape stem extract has antioxidant and anti-inflammatory activity due to its polyphenol content. However, robust human clinical trials are lacking, so the evidence for skin benefits is considered emerging rather than strong.
