Ingredient review
Hydrogenated Saussurea Lappa Extract
INCI: SAUSSUREA LAPPA EXTRACT HYDROGENATED
A gentle, antioxidant-rich botanical extract that may help calm skin, but research is limited and hydrogenation alters its natural composition.
In plain English
This is a processed version of an extract from the costus root, a plant used in traditional medicine. The hydrogenation step changes some of its natural compounds, which can reduce potential irritation and improve stability in skincare products. It's thought to help soothe skin and fight free radicals, but we don't have a lot of modern research on how well it works in cosmetics.

Quick decision guide
Useful, but context matters
Hydrogenated Saussurea Lappa Extract is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Hydrogenated Saussurea Lappa Extract.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A hydrogenated (chemically modified) extract from the root of Saussurea lappa, a plant native to the Himalayas. Hydrogenation adds hydrogen atoms to the extract, which can make it more stable and less likely to cause skin reactions.
How it works
The extract contains compounds like sesquiterpene lactones and flavonoids that have antioxidant and anti-inflammatory properties. Hydrogenation may reduce the reactivity of certain compounds, potentially lowering the risk of skin irritation while still providing soothing benefits.
Pros
Gentle on skin
Hydrogenation reduces the potential for irritation, making it suitable for sensitive skin types.
Antioxidant support
Contains flavonoids that can help neutralize free radicals, supporting overall skin health.
Cons and cautions
Limited research
There are very few modern studies on hydrogenated Saussurea lappa extract in skincare, so its benefits are not well-established.
Processing trade-offs
Hydrogenation may alter or reduce the potency of some naturally occurring active compounds.
Best for
- People with sensitive or easily irritated skin
- Those looking for gentle antioxidant support
Use caution if
- Anyone with a known allergy to costus root or related plants (Asteraceae family)
Usage tips
Safety summary
Hydrogenated Saussurea lappa extract is considered safe for topical use in cosmetics at low concentrations. The hydrogenation process reduces the risk of skin sensitization associated with the raw extract. However, individuals with allergies to plants in the Asteraceae family (e.g., ragweed, daisies) should exercise caution.
Research notes
Most evidence for the anti-inflammatory and antioxidant properties of Saussurea lappa comes from traditional use and laboratory studies. Direct clinical research on the hydrogenated form in skincare is scarce, so its efficacy is not strongly supported by modern science.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used at typical concentrations, though specific restrictions may apply to the non-hydrogenated form due to potential allergens.
- Common uses
- Soothing serums, Calming moisturizers, Anti-aging formulations
- Environmental note
- Saussurea lappa is listed as a vulnerable species in some regions due to overharvesting; look for sustainably sourced or cultivated extracts.
Good to know
- Saussurea lappa is also known as costus root and has a long history in Ayurvedic and traditional Chinese medicine.
- Hydrogenation is a common process used to stabilize oils and extracts, similar to how vegetable oils are turned into margarine.
