Ingredient review
Jiaogulan Leaf Extract
INCI: Gynostemma Pentaphyllum Leaf Extract
A gentle plant extract rich in antioxidants that may help calm skin and defend against environmental stress, though human skincare studies are still limited.
In plain English
Jiaogulan leaf extract comes from a vine sometimes called 'Southern Ginseng.' In skincare, it's used for its antioxidant content—substances that help protect skin from damage caused by pollution and UV exposure. Early research suggests it may also help soothe irritation, but most evidence comes from lab or animal studies, not large human trials. It's generally considered safe and non-irritating for most skin types.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A water-soluble extract obtained from the leaves of Gynostemma pentaphyllum, a climbing plant native to parts of Asia. The extract contains gypenosides (plant compounds similar to those in ginseng), flavonoids, and polysaccharides.
How it works
The gypenosides and flavonoids in the extract act as antioxidants, meaning they can neutralize free radicals (unstable molecules that can damage skin cells). This may help reduce oxidative stress from environmental aggressors. Some compounds in the extract also appear to calm inflammatory pathways in skin cells, potentially reducing redness or sensitivity.
Pros
Gentle antioxidant
Provides antioxidant support without common irritation, making it suitable for sensitive skin types.
Soothing potential
Early research indicates it may help calm redness and sensitivity, offering dual benefits in one ingredient.
Cons and cautions
Limited human evidence
Most studies are lab-based or on animals; robust human clinical trials for topical skincare are scarce.
Variable quality
As a natural extract, its potency depends on growing conditions and processing, leading to batch-to-batch inconsistency.
Best for
- Anyone looking for a gentle, plant-based antioxidant
- People with normal to combination skin who want extra environmental protection
Use caution if
- Those with known allergies to plants in the Cucurbitaceae family (e.g., cucumber, melon, squash)
Usage tips
Safety summary
Jiaogulan leaf extract has a low irritation and comedogenic risk based on available data. It is not known to be phototoxic or sensitizing. As with any botanical, patch testing is recommended for those with sensitive skin or plant allergies.
Research notes
Most research on Gynostemma pentaphyllum focuses on oral consumption for wellness. Topical studies are preliminary, showing antioxidant and anti-inflammatory activity in cell and animal models. Human skincare studies are needed to confirm efficacy.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used as a topical ingredient at typical concentrations.

Good to know
- Jiaogulan is sometimes called 'Southern Ginseng' because it contains gypenosides, which are structurally similar to ginseng's active compounds.
- The extract is water-soluble, so it's typically found in water-based formulas like serums and toners.
