Ingredient review
Lime Flower Extract
INCI: Citrus Aurantifolia Flower Extract
A gentle botanical extract that adds a light citrus scent and a touch of antioxidant support, but research on its direct skin benefits is limited.
In plain English
Lime flower extract is made from the blossoms of the lime tree. It's used in skincare mainly for its pleasant, light citrus fragrance and as a source of natural antioxidants that can help protect skin from environmental stress. Because it's a flower extract, it's generally mild, but like any plant ingredient, it can cause sensitivity in some people.

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
An extract derived from the flowers of the lime tree (Citrus aurantifolia), typically obtained through steam distillation or solvent extraction. It contains volatile aromatic compounds and flavonoids.
How it works
In a cosmetic product, lime flower extract primarily contributes a fresh citrus scent. The flavonoids present may offer mild antioxidant activity, helping to neutralize free radicals on the skin's surface, though the effect is subtle at typical use levels.
Pros
Natural fragrance
Provides a fresh, natural citrus scent without synthetic perfumes, which can be appealing for clean beauty formulations.
Mild antioxidant
Contains flavonoids that may help protect skin from minor environmental damage, though the effect is subtle.
Cons and cautions
Limited evidence
There is very little published research specifically on lime flower extract's effects on skin, so its benefits are mostly theoretical.
Potential allergen
As a citrus-derived ingredient, it may cause contact dermatitis or allergic reactions in people with citrus sensitivities.
Best for
- People who enjoy natural citrus-scented products
- Those looking for a mild botanical with antioxidant potential
Use caution if
- Individuals with known citrus allergies
- Those with highly reactive or sensitized skin
Usage tips
Safety summary
Generally recognized as safe for cosmetic use at low concentrations. The main risk is allergic reaction in citrus-sensitive individuals. Avoid contact with eyes and broken skin.
Research notes
Research on lime flower extract specifically is sparse. Most evidence is extrapolated from studies on other citrus flower extracts, which show antioxidant and anti-inflammatory potential in vitro. Human studies are lacking.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the US and EU as a fragrance ingredient and botanical extract, with no specific restrictions at typical use levels.
- Common uses
- Facial toners, Serums, Moisturizers, Fragranced products
- Environmental note
- Lime trees are widely cultivated, but sourcing from sustainable farms helps reduce environmental impact. The extraction process may use solvents, so look for CO2-extracted or steam-distilled versions if purity is a concern.
Good to know
- Lime flower extract is different from lime fruit extract or lime oil — it comes from the blossoms, not the fruit or peel.
- It is often used in small amounts primarily for scent, so its skin benefits are secondary to its fragrance role.
