What it is
An extract derived from the wood of the Eysenhardtia polystachya tree, commonly known as Palo Santo or Kidneywood. It contains flavonoids and other phenolic compounds that give it antioxidant and anti-inflammatory activity.
How it works
The flavonoids in the extract neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It also appears to calm inflammatory pathways, which can reduce visible redness and sensitivity when applied topically.
Pros
Gentle antioxidant
Provides protection from free radicals without the irritation that some stronger antioxidants can cause, making it suitable for sensitive skin.
Soothing potential
May help calm redness and inflammation, which is beneficial for conditions like mild rosacea or post-exfoliation sensitivity.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so its real-world benefits are not fully proven.
Rare allergen risk
As a plant extract, it can cause allergic reactions in a small number of people, especially those with legume allergies.
Best for
- Anyone looking for a natural antioxidant in their routine
- People with sensitive or reactive skin who want gentle soothing ingredients
Use caution if
- Those with known allergies to plants in the Fabaceae family (legumes)
Usage tips
Safety summary
Palo Santo wood extract is considered safe for topical use with a low risk of irritation. As with any botanical, patch testing is recommended for those with sensitive skin or plant allergies.
Research notes
Preliminary studies show antioxidant and anti-inflammatory activity in vitro, but clinical evidence in humans is sparse. More research is needed to confirm its efficacy in skincare.
Common label clues

- 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU, with no specific restrictions beyond standard cosmetic ingredient regulations.
