Ingredient review
Citrus Leaf Extract
INCI: Citrus Species Leaf Extract
A gentle botanical extract that may help calm skin and fight free radicals, but research is still limited.
In plain English
Citrus leaf extract is made from the leaves of citrus trees like orange or lemon. In skincare, it's used to provide antioxidants that help protect skin from environmental damage, and it may have mild soothing effects. It's generally considered gentle and safe for most skin types, but because it's a plant extract, there's always a small chance of irritation for very sensitive skin.

What it is
Citrus leaf extract is a natural ingredient derived from the leaves of various citrus species (e.g., orange, lemon, grapefruit). It contains flavonoids, polyphenols, and other plant compounds that can benefit the skin.
How it works
The extract works primarily as an antioxidant, meaning it helps neutralize free radicals (unstable molecules that can damage skin cells). It may also have mild anti-inflammatory properties, which can help calm redness or irritation.
Pros
Gentle antioxidant
Provides free radical protection without the irritation potential of some stronger antioxidants, making it suitable for daily use.
Soothing potential
May help calm minor redness or inflammation, which can benefit those with occasional sensitivity.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; human clinical trials on skin are sparse, so effectiveness is not fully proven.
Allergy risk
Citrus-derived ingredients can cause allergic reactions in some people, especially those with citrus allergies, so a patch test is recommended.
Best for
- People looking for gentle antioxidant support
- Those with normal to combination skin who want a natural ingredient
Use caution if
- Individuals with known citrus allergies should patch test first
- Those with extremely reactive or damaged skin may want to avoid until healed
Usage tips
Safety summary
Citrus leaf extract is considered safe for topical use in cosmetics at typical concentrations. As with any plant extract, there is a low risk of irritation or allergy, especially for those with citrus sensitivities. Always patch test a new product.
