Ingredient review
Hydrolyzed Sundew Leaf
INCI: HYDROLYZED DROSERA ROTUNDIFOLIA LEAF
A gentle, plant-derived ingredient that may help calm redness and provide antioxidant support, though research is still emerging.
In plain English
This is a processed extract from the sundew plant, a carnivorous plant that grows in bogs. The leaves are broken down (hydrolyzed) to release compounds that can soothe skin and fight free radicals. It's a mild ingredient, not a strong active, so it works best as a supporting player in calming or antioxidant formulas.

What it is
A hydrolyzed (enzyme-treated) extract of the leaves of Drosera rotundifolia, commonly known as roundleaf sundew. The plant has a history of traditional use for its soothing properties.
How it works
The hydrolysis process breaks down plant proteins and polysaccharides into smaller, more skin-available molecules. These compounds are thought to have antioxidant and anti-inflammatory effects, helping to calm irritation and protect skin from environmental stress.
Pros
Gentle soothing potential
Traditional use and preliminary research suggest it may help calm redness and irritation without causing further sensitivity.
Antioxidant support
Contains compounds that can neutralize free radicals, helping to protect skin from environmental damage like pollution and UV stress.
Cons and cautions
Limited scientific backing
Most evidence comes from traditional use or lab studies; there are few well-controlled human trials confirming its benefits in skincare.
Sustainability concerns
Sundew is a wild-harvested plant in some regions, which can raise ecological concerns if not sourced responsibly.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle antioxidant boost in their routine
Use caution if
- Anyone with a known allergy to sundew or related plants (Droseraceae family)
Usage tips
Safety summary
Hydrolyzed sundew leaf is considered safe for topical use at typical cosmetic concentrations. Allergic reactions are rare but possible in individuals sensitive to the plant family. Avoid if you have a known allergy to sundew or related species.
Research notes
Research on hydrolyzed sundew leaf in skincare is limited. In vitro studies suggest antioxidant and anti-inflammatory activity, but human clinical data are sparse. More studies are needed to confirm its efficacy and optimal use.
Common label clues
- Typical concentration
- Typically used at 0.1–2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US, with no specific restrictions at typical use levels.
- Common uses
- Serums, Moisturizers, Soothing masks
- Environmental note
- Sundew is often wild-harvested from peat bogs, which are sensitive ecosystems. Look for brands that use sustainably cultivated or certified organic sources.
Good to know
- Sundew is a carnivorous plant that traps insects with sticky droplets on its leaves, but the hydrolyzed extract is safe and non-irritating for skin.
- The hydrolysis process makes the plant's active compounds more bioavailable to the skin compared to a simple extract.
