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
An extract from the leaves of lemongrass (Cymbopogon citratus) that has been oxidized, a process that may alter its active compounds and potentially enhance certain properties like stability or antioxidant activity.
How it works
It provides antioxidant benefits by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. The oxidation process may also create new compounds that have soothing or antimicrobial effects, though this is less studied.
Pros
Antioxidant support
Helps neutralize free radicals from environmental stressors, which can support overall skin health and reduce signs of aging.
Gentle on skin
Unlikely to cause irritation or clog pores, making it a safe choice for most skin types, including oily and acne-prone skin.
Cons and cautions
Limited research
Most studies focus on fresh lemongrass extract, not the oxidized version, so the specific benefits and safety are less established.
Potential allergen
As a botanical extract, it may cause allergic reactions in people sensitive to lemongrass or related plants, though this is rare.
Best for
- People looking for natural antioxidant ingredients
- Those with normal to combination skin
Use caution if
- Individuals with known citrus or grass allergies
- Those with highly sensitive skin who react to botanical extracts
Usage tips
Safety summary
Oxidized lemongrass leaf extract is considered safe for topical use in cosmetics at typical concentrations. Allergic reactions are rare but possible, especially for those with plant allergies.
Research notes
Research on lemongrass extract shows antioxidant and antimicrobial activity, but specific studies on the oxidized form are scarce. Most evidence is based on traditional use and in vitro studies.
