Ingredient review
Strychnos Potatorum Seed Oil
INCI: STRYCHNOS POTATORUM SEED OIL
A gentle, plant-based oil that helps soften and condition skin, but research on its benefits is still limited.
In plain English
Strychnos potatorum seed oil comes from the seeds of a tree native to India and Southeast Asia. In skincare, it works as an emollient, meaning it helps soften and smooth the skin by forming a light barrier that reduces water loss. It is generally well-tolerated and unlikely to clog pores, making it a nice option for dry or sensitive skin types. However, there isn't much scientific research yet on its specific benefits compared to more studied oils like jojoba or squalane.

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 fixed oil extracted from the seeds of the Strychnos potatorum tree, also known as the clearing nut tree. The oil is rich in fatty acids like oleic and linoleic acid, which are common in many skincare oils.
How it works
When applied to the skin, the oil spreads easily and fills the gaps between skin cells, helping to restore the skin's natural barrier. This reduces transepidermal water loss (water that evaporates from the skin's surface) and leaves the skin feeling softer and more supple.
Pros
Gentle on skin
This oil has a low irritation and comedogenic risk, making it suitable for sensitive or acne-prone skin types.
Lightweight feel
Unlike heavier oils, it absorbs quickly without leaving a sticky or greasy residue, so it works well under makeup or sunscreen.
Cons and cautions
Limited research
There are very few peer-reviewed studies on this specific oil, so its claimed benefits are mostly based on traditional use and ingredient similarity to other oils.
Potential allergen
As with any botanical oil, there is a small chance of allergic reaction, especially for those with plant allergies.
Best for
- People with dry or normal skin looking for a lightweight moisturizing oil
- Those who prefer plant-based, minimally processed ingredients
Use caution if
- Anyone with a known allergy to Strychnos potatorum or related plants
- Those seeking proven anti-aging or acne-fighting ingredients
