Ingredient review
Acetylated Vetiver Root Extract
INCI: VETIVERIA ZIZANIOIDES ROOT EXTRACT ACETYLATED
A gentle, antioxidant-rich ingredient that may help calm skin and protect against environmental stress.
In plain English
This is a version of vetiver root extract that has been chemically modified (acetylated) to make it more stable and easier to blend into skincare products. Vetiver is a grass known for its earthy scent, and its root extract contains compounds that can help soothe skin and fight free radicals (unstable molecules that can damage skin cells). The acetylation process doesn't change its core benefits but improves how it works in a formula.

What it is
A semi-synthetic derivative of vetiver root extract, created by adding an acetyl group to the natural extract to enhance its stability and compatibility with cosmetic formulations.
How it works
It provides antioxidant activity by neutralizing free radicals, which helps protect skin from environmental aggressors like pollution and UV exposure. It also has mild anti-inflammatory properties that can help calm irritated or sensitive skin.
Pros
Gentle antioxidant
Provides antioxidant protection without the irritation that some stronger antioxidants can cause, making it suitable for sensitive skin.
Soothing properties
May help calm redness and irritation, offering a dual benefit of protection and comfort in one ingredient.
Cons and cautions
Limited research
Most studies focus on unmodified vetiver extract; the acetylated version has less published evidence, so its benefits are inferred rather than proven.
Low concentration used
Typically used at low levels (under 1%), so its effects may be subtle and not as dramatic as higher-concentration antioxidants.
Best for
- People with normal to sensitive skin looking for gentle antioxidant support
- Those seeking soothing ingredients for redness or irritation
Use caution if
- Individuals with known allergies to vetiver or grass-derived ingredients
Usage tips
Safety summary
