What it is
An herbal extract obtained from the leaves of Cymbopogon nardus, a grass species known for its citronella oil content. It is rich in compounds like citronellal and geraniol, which give it its characteristic scent.
How it works
The extract works primarily as a natural fragrance ingredient. Its antimicrobial components can help reduce surface bacteria on the skin, but the effect is mild. It also provides a refreshing sensation when applied.
Pros
Natural scent
Provides a fresh, citrusy aroma without synthetic fragrances, making it appealing for natural product lovers.
Mild cleansing support
Its gentle antimicrobial action can help reduce surface bacteria, which may benefit oily or acne-prone skin types.
Cons and cautions
Irritation potential
The volatile oils in citronella can cause redness, stinging, or allergic reactions, especially on sensitive or damaged skin.
Limited skin benefits
Beyond fragrance and mild antimicrobial effects, it offers little proven benefit for hydration, anti-aging, or barrier repair.
Best for
- People who enjoy natural, botanical-scented products
- Those with normal to oily skin looking for a mild cleansing boost
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
Usage tips
Safety summary
Generally safe for most skin types when used at low concentrations, but poses a moderate risk of irritation and allergic contact dermatitis for sensitive individuals. Avoid on broken or inflamed skin.
Research notes
Studies confirm the antimicrobial activity of citronella oil, but evidence for skin benefits from the extract alone is limited. Most research focuses on its use as an insect repellent rather than a cosmetic ingredient.
Common label clues
- Typical concentration
- 0.1% to 1% in leave-on products
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets as a fragrance ingredient, with concentration limits in some regions to reduce sensitization risk.
- Common uses
- Facial cleansers, Body lotions, Tonics
- Environmental note
- Citronella grass is widely cultivated and considered a renewable resource, but large-scale farming may impact local ecosystems.
Good to know
- Citronella extract is often confused with lemongrass extract, but they come from different plant species.
- The extract is not the same as citronella oil, which is more concentrated and more likely to cause irritation.
