Ingredient review
Winter Grass Extract
INCI: CYMBOPOGON WINTERIANUS HERB EXTRACT MODIFIED
A gentle plant extract that may help calm skin, but research is limited and it's often used for its mild scent.
In plain English
This is an extract from a type of grass (Cymbopogon winterianus, related to citronella) that has been modified in some way during processing. In skincare, it's added to products like serums and toners to provide a soothing feeling and a light, grassy fragrance. Because it's a natural extract, its exact composition can vary, and there isn't a lot of strong research proving it does much beyond adding a pleasant scent and a touch of antioxidant activity.

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 modified herbal extract from the leaves of Cymbopogon winterianus, a grass species known for its aromatic properties. The 'modified' label indicates it has been processed (e.g., purified or chemically altered) to standardize its properties or reduce potential irritants.
How it works
In a cosmetic product, this extract is believed to work primarily through its natural antioxidant compounds, which can help neutralize free radicals on the skin's surface. It may also provide a mild anti-inflammatory effect, contributing to a temporary soothing sensation. However, its main role in many formulations is as a natural fragrance component.
Pros
Natural origin
Derived from a plant source, which appeals to those seeking more natural skincare ingredients.
Mild and refreshing
Provides a light, grassy scent and a cooling sensation that can feel pleasant in toners or lightweight serums.
Cons and cautions
Limited evidence
There is very little published research specifically on this modified extract's effectiveness for skin health, so its benefits are mostly anecdotal.
Potential allergen
As a plant extract, it can cause allergic reactions in people sensitive to grasses or related plants, and the 'modified' processing doesn't guarantee hypoallergenicity.
Best for
- Those looking for a natural, mild fragrance in their skincare
- People with normal or combination skin who want a light, refreshing feel
Use caution if
- Individuals with known allergies to grasses or citronella
- Those with very sensitive or reactive skin, as natural extracts can sometimes cause irritation
Usage tips
Safety summary
Considered safe for most people when used in low concentrations in cosmetics. However, as with any plant extract, there is a small risk of skin irritation or allergic reaction, particularly for those with grass allergies.
Research notes
Research on this specific modified extract is scarce. Most evidence comes from studies on the whole plant's essential oil, which has shown antioxidant and antimicrobial properties, but these findings do not directly apply to the modified extract used in skincare.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for use in cosmetics by the FDA and EU CosIng database when used as a fragrance or skin-conditioning agent.
- Common uses
- Soothing serums, Refreshing toners, Calming masks
- Environmental note
- Sourced from a renewable plant resource, but processing may involve solvents. Look for sustainably harvested sources if this is a concern.
Good to know
- Cymbopogon winterianus is the same species used to produce citronella oil, though this extract is processed differently.
- The 'modified' designation often means the extract has been treated to remove certain compounds, but the exact method is rarely specified on labels.
