Ingredient review
Lime Seed Oil
INCI: Citrus Aurantifolia Seed Oil
A gentle, antioxidant-rich oil that hydrates and soothes skin without clogging pores.
In plain English
Lime seed oil is a natural oil pressed from the seeds of limes. In skincare, it works as an emollient, meaning it softens and smooths the skin by filling in tiny gaps between skin cells. It also contains antioxidants that help protect skin from environmental stressors like pollution. Because it's non-greasy and low on the comedogenic scale, it's a good option for people with oily or acne-prone skin who still want moisture.

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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Lime seed oil is a fixed oil extracted from the seeds of Citrus aurantifolia (lime). It is rich in fatty acids like linoleic acid and contains natural antioxidants such as vitamin E.
How it works
When applied to the skin, lime seed oil forms a thin, breathable barrier that locks in moisture and prevents water loss. Its fatty acids help reinforce the skin's natural lipid barrier, while antioxidants neutralize free radicals that can cause premature aging.
Pros
Lightweight hydration
Unlike heavier oils, lime seed oil absorbs quickly and doesn't leave a sticky or greasy residue, making it ideal for daytime use or under makeup.
Antioxidant protection
The natural antioxidants in lime seed oil help defend skin against free radicals from UV exposure and pollution, which can contribute to fine lines and dullness.
Cons and cautions
Potential allergen
Because it comes from citrus, people with citrus allergies may experience redness or itching. Always patch test before widespread use.
Limited research
While seed oils in general are well-studied, specific studies on lime seed oil are sparse, so some benefits are inferred from similar oils rather than proven directly.
Best for
- People with oily or combination skin looking for a non-comedogenic moisturizer
- Anyone wanting a natural antioxidant boost in their routine
Use caution if
- Individuals with a known allergy to citrus fruits or citrus oils
Usage tips
Safety summary
Lime seed oil is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, though individuals with citrus allergies should exercise caution. Always perform a patch test before first use.
Research notes
Research on lime seed oil specifically is limited, but studies on similar seed oils (e.g., grape seed, sunflower) support its emollient and antioxidant benefits. The fatty acid profile of lime seed oil is comparable to other non-comedogenic oils.
Common label clues
- Typical concentration
- 0.5% to 5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used at typical concentrations.
- Common uses
- Moisturizers, Serums, Lip balms
- Environmental note
- Lime seed oil is a byproduct of lime juice production, making it a relatively sustainable ingredient that reduces waste.
Good to know
- Lime seed oil is different from lime essential oil — it is not phototoxic and does not contain the volatile compounds that can cause sun sensitivity.
- Look for cold-pressed, unrefined versions to retain the most antioxidants.
