INCI: Oxalis Hedysaroides Extract
A gentle botanical extract with antioxidant potential, but research is limited and benefits are not yet well-established.
In plain English
This is an extract from a plant called Oxalis hedysaroides, sometimes known as fire fern.

What it is
A natural extract derived from the leaves of the Oxalis hedysaroides plant, a species of wood sorrel native to tropical regions. It contains various plant compounds, including flavonoids and phenolic acids, which are thought to contribute to its antioxidant activity.
How it works
The extract works primarily by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. This antioxidant action helps protect the skin from oxidative stress caused by UV exposure and pollution. Additionally, some compounds in the extract may have mild anti-inflammatory effects, helping to reduce redness and soothe sensitive skin.
Pros
Gentle antioxidant
Provides mild protection against free radicals without common irritation, making it suitable for sensitive skin routines.
Natural origin
Derived from a plant source, appealing to consumers who prefer naturally sourced ingredients in their skincare.
Cons and cautions
Limited research
There are very few peer-reviewed studies on this specific extract, so its benefits and safety profile are not as well-established as more common botanicals.
Uncertain efficacy
Without robust clinical data, it's unclear how much antioxidant or soothing benefit the extract actually provides in a finished product.
Best for
- Anyone looking for a gentle, natural antioxidant ingredient
- People with normal to combination skin who want extra environmental protection
Use caution if
- Individuals with known allergies to Oxalis species or related plants
- Those seeking proven, high-efficacy antioxidant ingredients
Usage tips
Safety summary
