Ingredient review
Polyalthia Longifolia Wood Extract
INCI: POLYALTHIA LONGIFOLIA WOOD EXTRACT
A gentle botanical extract with antioxidant potential, but research on its topical benefits is still limited.
In plain English
This is an extract made from the wood of the Polyalthia longifolia tree, also known as the false ashoka or mast tree. In skincare, it's added for its ability to help protect skin from environmental stress and provide mild soothing effects. Because it comes from wood, it contains natural compounds like flavonoids and polyphenols that can act as antioxidants. However, compared to more studied ingredients like green tea or vitamin C, there is less scientific evidence specifically for this extract's benefits on skin.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A natural extract derived from the wood of the Polyalthia longifolia tree, a tropical evergreen native to South Asia. The extract is rich in bioactive compounds such as flavonoids, alkaloids, and phenolic acids.
How it works
The antioxidant compounds in the extract help neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. It may also have mild anti-inflammatory effects, helping to calm irritated skin. In a formulation, it acts as a skin-conditioning agent, contributing to the overall protective and soothing profile of the product.
Pros
Gentle antioxidant support
The extract contains natural antioxidants that can help protect skin from daily environmental damage without causing irritation, making it suitable for sensitive skin types.
Soothing potential
Early research suggests anti-inflammatory properties that may help calm redness or minor irritation, adding a soothing benefit to products.
Cons and cautions
Limited skin-specific research
Most studies on Polyalthia longifolia focus on its antimicrobial or general antioxidant activity, not specifically on how it benefits human skin in cosmetic formulations.
Less potent than established antioxidants
Compared to well-researched antioxidants like vitamin C or ferulic acid, this extract's antioxidant capacity is less documented, so its real-world impact may be modest.
Best for
- Anyone looking for a gentle, natural antioxidant in their routine
- Those with normal to combination skin who want extra environmental protection
Use caution if
- Individuals with known allergies to plants in the Annonaceae family (e.g., custard apple, soursop)
Usage tips
Safety summary
Polyalthia Longifolia Wood Extract is considered safe for topical use in cosmetics at typical concentrations. Allergic reactions are rare, but as with any plant extract, patch testing is recommended for those with sensitive skin or plant allergies.
Research notes
Current evidence is primarily from in vitro (lab) studies showing antioxidant and antimicrobial activity. Human clinical trials on skin benefits are lacking, so the ingredient's efficacy in skincare is supported mainly by traditional use and preliminary research.
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 subject to specific restrictions.

- Environmental note
- The tree is widely cultivated and not considered endangered. Wood extracts are a byproduct of forestry, making this a relatively sustainable ingredient.
Good to know
- Polyalthia longifolia is also known as the 'mast tree' or 'false ashoka' and is commonly planted as an ornamental tree in tropical regions.
- The extract is often used in traditional medicine, but cosmetic applications are still emerging.
