Ingredient review
Round-Leaf Sundew Extract
INCI: Drosera Rotundifolia Extract
A gentle botanical extract with antioxidant and soothing potential, but human skincare research is limited.
In plain English
Round-leaf sundew extract comes from a small carnivorous plant that grows in bogs. In skincare, it's used for its antioxidant and soothing effects, meaning it may help calm irritated skin and protect against environmental damage. However, most of what we know comes from lab studies, not large human trials, so its benefits are promising but not yet proven.

What it is
An extract derived from the leaves and stems of Drosera rotundifolia, a carnivorous plant that traps insects with sticky droplets. It contains compounds like flavonoids, tannins, and naphthoquinones, which are thought to contribute to its biological activity.
How it works
In cosmetic products, the extract is believed to work as an antioxidant, neutralizing free radicals that can damage skin cells. Its naphthoquinones may also have anti-inflammatory effects, potentially reducing redness and irritation when applied topically.
Pros
Gentle on skin
The extract has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Antioxidant support
It contains flavonoids that help protect skin from oxidative stress caused by pollution and UV exposure.
Cons and cautions
Limited research
Most evidence comes from lab studies; there are few well-designed human trials proving its benefits for skin.
Potential allergen
As a botanical extract, it may cause allergic reactions in people sensitive to plant-based ingredients.
Best for
- People with sensitive or easily irritated skin
- Those looking for natural antioxidant ingredients in their routine
Use caution if
