Ingredient review
Butea Superba Root Extract
INCI: Butea Superba Root Extract
A plant root extract with traditional use and early research suggesting antioxidant benefits, but clinical skincare evidence is still limited.
In plain English
Butea superba root extract comes from a vine native to Thailand. In skincare, it's added for its antioxidant content, which may help protect skin from environmental stress. Some early studies also suggest it might support skin firmness, but most of the evidence comes from lab or animal research, not large human trials. It's generally considered gentle and safe for most skin types.

What it is
A natural extract obtained from the roots of Butea superba, a climbing plant in the pea family. The extract contains flavonoids and other polyphenolic compounds that give it antioxidant activity.
How it works
The flavonoids in the extract can neutralize free radicals, potentially reducing oxidative damage to skin cells. Some compounds in the root may also influence enzymes related to collagen breakdown, though this effect is not yet well-documented in human skin.
Pros
Antioxidant potential
Contains flavonoids that can help neutralize free radicals, which may reduce environmental stress on skin over time.
Gentle on skin
Reported irritation and comedogenic risks are low, making it suitable for sensitive and acne-prone skin types when properly formulated.
Cons and cautions
Limited clinical evidence
Most research is in lab or animal models; large, well-controlled human studies on topical use are lacking, so benefits are not fully proven.
Variable quality
As a natural extract, the concentration of active compounds can vary by harvest, processing, and supplier, leading to inconsistent results between products.
Best for
- Anyone looking for additional antioxidant support in their routine
- People interested in plant-based, traditional ingredients
Use caution if
- Those with known allergies to plants in the Fabaceae (pea) family
- Anyone seeking ingredients with strong clinical evidence for anti-aging
Usage tips
Safety summary
Butea superba root extract is considered safe for topical cosmetic use with low irritation and comedogenic potential. However, due to limited human data, it should be viewed as a supportive rather than primary active ingredient.
Research notes
Early research shows antioxidant and potential anti-collagenase activity in vitro and in animal models. Human clinical studies on topical application for skin firmness or anti-aging are scarce, so the evidence level is emerging.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used as a topical ingredient at typical concentrations. Not approved for medical or therapeutic claims.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Butea superba is a wild-harvested plant in some regions; sustainable sourcing practices are important to avoid overharvesting and protect native ecosystems.
Good to know
- Butea superba is sometimes called 'Red Kwao Krua' and is used in traditional Thai medicine, but it should not be confused with 'White Kwao Krua' (Pueraria mirifica), which has different properties.
- The extract is often used at low concentrations (under 2%) in skincare, so it is rarely the sole active ingredient in a formula.
