Formosana Sweetgum Fruit Extract
INCI: Liquidambar Formosana Fruit Extract
A gentle, antioxidant-rich plant extract that may help calm skin and protect against environmental stress, though research is still emerging.
In plain English
This is an extract from the fruit of the Formosan sweetgum tree, a plant native to parts of Asia. In skincare, it's used as a source of antioxidants—substances that help neutralize unstable molecules called free radicals, which can damage skin cells. It's also thought to have soothing properties, meaning it may help reduce redness or irritation. Because it's a natural extract, its effects can vary depending on how it's processed and formulated.

What it is
A natural fruit extract derived from Liquidambar formosana, a tree in the sweetgum family. The fruit is rich in polyphenols and other bioactive compounds that have antioxidant and anti-inflammatory potential.
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 protect collagen and elastin fibers, and may reduce signs of environmental aging. The anti-inflammatory compounds may also calm irritated skin by reducing the activity of pro-inflammatory enzymes.
Pros
Gentle antioxidant
Provides free-radical protection without common irritation, making it suitable for sensitive skin types.
Soothing potential
May help calm redness and inflammation, offering dual benefits in one ingredient.
Cons and cautions
Limited research
Most evidence comes from lab studies; human skin benefits are not yet well-documented in peer-reviewed trials.
Variable potency
As a natural extract, its active compound levels can fluctuate between batches, affecting consistency.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- Those with sensitive or reactive skin who want soothing ingredients
Use caution if
- People with known allergies to sweetgum or related plants (rare)
