Hydrolyzed Rhubarb Root Extract
INCI: HYDROLYZED RHEUM OFFICINALE ROOT EXTRACT
A gentle, antioxidant-rich plant extract that may help calm skin and fight free radical damage, though research is still early.
In plain English
This is a processed version of rhubarb root extract, meaning the plant's active compounds have been broken down into smaller pieces so your skin can absorb them more easily. It's thought to help protect skin from environmental stress and reduce redness, but it's not a heavy-duty treatment.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A water-soluble extract from the root of Rheum officinale (Chinese rhubarb) that has been hydrolyzed (broken down with water and enzymes) to make its active compounds more bioavailable for skin.
How it works
It provides antioxidant activity by donating electrons to neutralize free radicals, which can otherwise damage skin cells. The hydrolysis process also releases smaller peptides and polyphenols that may help calm irritation and support the skin's natural barrier.
Pros
Gentle antioxidant
Provides free radical protection without the irritation sometimes seen with stronger antioxidants like vitamin C, making it suitable for sensitive skin.
Soothing potential
Early research suggests it may help calm redness and inflammation, which can benefit those with reactive or stressed skin.
Cons and cautions
Limited evidence
Most research is lab-based or on animals; there are few high-quality human studies confirming its benefits in skincare.
Not a standalone treatment
It works best as part of a broader antioxidant or soothing formula, not as a single hero ingredient for major skin concerns.
Best for
- Anyone looking for a gentle, plant-based antioxidant
- Those with sensitive or easily irritated skin seeking a calming ingredient
Use caution if
- Individuals with a known allergy to rhubarb or related plants (Polygonaceae family)
Usage tips
Safety summary
Considered safe for topical use in cosmetics at typical concentrations. Allergic reactions are rare but possible in individuals sensitive to rhubarb or related plants. Avoid if you have a known allergy.
Research notes
In vitro studies show antioxidant and anti-inflammatory activity, but clinical trials on human skin are lacking. More research is needed to confirm efficacy and optimal concentrations.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Approved for cosmetic use in the EU and US as a natural extract; no specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Soothing serums, Anti-aging creams, Calming masks
- Environmental note
- Rhubarb is a cultivated crop, so sourcing is generally sustainable, but check for organic or wild-harvested certifications if concerned about pesticides.
Good to know
- Hydrolysis makes the extract water-soluble, so it works well in gel-based or lightweight formulas.
- The root of Rheum officinale has a long history in traditional Chinese medicine, but cosmetic use is relatively new.
