Ingredient review
Spatholobus Bark Extract
INCI: SPATHOLOBUS PARVIFLORUS BARK EXTRACT
A gentle plant extract with antioxidant potential, but research is still early and benefits are not yet proven in human skin.
In plain English
Spatholobus bark extract comes from the bark of a tropical vine. In skincare, it's added for its antioxidant content—meaning it may help protect skin from damage caused by pollution and UV exposure. It also has a history of use in traditional medicine for soothing inflammation, which is why it's sometimes included in calming products. However, most of what we know comes from lab studies, not large human trials, so treat it as a nice bonus ingredient rather than a hero active.

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
An extract derived from the bark of Spatholobus parviflorus, a woody vine native to parts of Asia. The bark is dried, ground, and then soaked in a solvent (like water or alcohol) to pull out beneficial compounds such as flavonoids and phenolic acids.
How it works
The flavonoids and other polyphenols in the extract act as antioxidants, meaning they can neutralize free radicals (unstable molecules that can damage skin cells and accelerate aging). Some compounds may also reduce the activity of inflammatory messengers, potentially calming redness or irritation.
Pros
Gentle antioxidant
The extract contains flavonoids that can help protect skin from daily environmental damage without causing irritation for most people.
Traditional use supports safety
Long history of oral use in herbal medicine suggests low toxicity, and cosmetic concentrations are even lower, making it a low-risk addition.
Cons and cautions
Weak evidence in skincare
Most studies are lab-based or on animals; there are no large, peer-reviewed human trials proving it visibly improves skin health or appearance.
Rare allergy risk
As a plant extract, it contains multiple compounds that could trigger contact dermatitis in very sensitive individuals, especially those with legume allergies.
Best for
- Anyone looking for extra antioxidant support in their routine
- People with normal to dry skin who want a gentle, plant-based ingredient
Use caution if
- Those with known allergies to plants in the Fabaceae (legume) family should patch-test first
Usage tips
Safety summary
Spatholobus bark extract is considered safe for topical use at cosmetic concentrations. Irritation and allergy are rare. As with any new botanical, patch-testing is recommended for those with sensitive skin or plant allergies.
Research notes
Research is limited to in vitro (lab) studies showing antioxidant and anti-inflammatory activity. No robust clinical trials on human skin exist yet, so evidence is preliminary.
Common label clues
- Typical concentration
- Typically used at 0.1–2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used at typical concentrations. Not specifically regulated as a drug ingredient.
- Common uses
- Serums, Moisturizers, Face masks
- Environmental note
- Spatholobus parviflorus is a wild-harvested vine in some regions; sustainable sourcing practices are important to avoid overharvesting.
Good to know
- The plant is also known as 'blood vine' in traditional Chinese medicine, where it's used for circulatory health.
- Because it's a natural extract, its composition can vary between batches, which is why it's rarely the star ingredient in a formula.
