Ingredient review
Cajuput Fruit Extract
INCI: MELALEUCA LEUCADENDRON FRUIT EXTRACT
A gentle, antioxidant-rich plant extract that may help protect skin from environmental stress, though research is still emerging.
In plain English
This ingredient comes from the fruit of the cajuput tree, a relative of the tea tree. In skincare, it's used mainly for its antioxidant content, which can help neutralize free radicals (unstable molecules that can damage skin cells). It also has mild soothing properties, making it a nice addition to products for sensitive or stressed skin. However, it's not as well-studied as more common antioxidants like vitamin C or green tea.

What it is
A natural extract derived from the fruit of Melaleuca leucadendron, a tree native to Southeast Asia and Australia. The fruit is rich in polyphenols and flavonoids, which are plant compounds known for their antioxidant activity.
How it works
The polyphenols in the extract donate electrons to neutralize free radicals, preventing them from causing oxidative damage to skin cells. This can help reduce signs of environmental aging and support overall skin health. It may also have mild anti-inflammatory effects, calming redness or irritation.
Pros
Gentle antioxidant
Provides free-radical protection without the irritation that some stronger antioxidants can cause, making it suitable for sensitive skin.
Soothing potential
May help calm redness and inflammation, adding a comforting effect to moisturizers or serums.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so its real-world benefits are less certain than for well-studied antioxidants.
Lower potency
Compared to vitamin C or ferulic acid, this extract has a milder antioxidant capacity, so it's best used as a supporting ingredient rather than a primary active.
Best for
- Anyone looking for a gentle, natural antioxidant
- People with sensitive or reactive skin who want extra protection
Use caution if
- Those with a known allergy to Melaleuca species (tea tree family)
