Score terms in plain English
Irritation risk

What it is
A cold-pressed vegetable oil extracted from the seeds of the Cacay tree (Fevillea trilobata), native to Colombia and other parts of South America. It contains high levels of linoleic acid (an omega-6 fatty acid) and vitamin E, along with smaller amounts of other antioxidants.
How it works
When applied to the skin, the oil's fatty acids help replenish the skin's natural lipid barrier, reducing water loss and keeping skin soft. Vitamin E acts as an antioxidant, helping to neutralize free radicals that can damage skin cells. Its lightweight texture allows it to spread easily without leaving a heavy film.
Pros
Lightweight feel
Absorbs quickly without leaving a greasy residue, making it comfortable for daytime use under makeup or sunscreen.
Barrier support
High linoleic acid content helps strengthen the skin's moisture barrier, which can reduce dryness and sensitivity over time.
Cons and cautions
Higher cost
Cacay oil is less common and more expensive than staple oils like jojoba or grapeseed, which may not fit every budget.
Limited research
While the individual components (linoleic acid, vitamin E) are well-studied, specific clinical studies on this oil are scarce.
Best for
- People with dry or dehydrated skin looking for a lightweight oil
- Those who want a non-comedogenic oil for daily moisturizing
Use caution if
- Individuals with a known allergy to nuts or seeds from the Cucurbitaceae family (pumpkin, squash, etc.) should patch test first
Usage tips
Safety summary
Generally considered safe for topical use. Patch test recommended for those with seed allergies. Avoid contact with eyes.
Research notes
Linoleic acid and vitamin E are well-documented for skin barrier support and antioxidant activity. Direct studies on Fevillea Trilobata Seed Oil are limited, but its composition suggests similar benefits to other high-linoleic oils.
