What it is
An herbal extract obtained from the leaves of Cymbopogon nardus (citronella grass), often processed with acetone as a solvent. The extract contains volatile oils like citronellal and geraniol, which give it its characteristic scent.
How it works
In a cosmetic product, citronella extract contributes fragrance and may provide a mild astringent effect by temporarily tightening the skin's surface. It does not have proven active skincare benefits like hydration or anti-aging, but it can help refresh oily or combination skin.
Pros
Natural scent
Provides a fresh, lemony aroma without synthetic fragrances, which some users prefer.
Mild astringent
Can help reduce excess oil and give a temporary tightening feel, useful for oily skin types.
Cons and cautions
Irritation risk
Contains volatile oils that can cause redness, stinging, or contact dermatitis in sensitive individuals.
Limited skincare benefit
Beyond fragrance and mild astringency, it offers no proven moisturizing, anti-aging, or antioxidant effects.
Best for
- People with normal to oily skin who enjoy botanical scents
- Those looking for a natural fragrance alternative in skincare
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Anyone with a known allergy to citronella or fragrance components
