What it is
A natural extract derived from the non-fruit parts of the lemon tree (Citrus limon), specifically the flowers, leaves, and stems. It contains various plant compounds like flavonoids and polyphenols that act as antioxidants.
How it works
In a cosmetic product, this extract works primarily by donating electrons to neutralize free radicals (unstable molecules that can damage skin cells). It also contributes to the product's overall sensory profile with a light, fresh scent, and may help condition the skin by providing a small amount of natural moisture.
Pros
Gentle antioxidant
Provides antioxidant protection without the acidity or irritation risk of lemon fruit or peel extracts, making it suitable for most skin types.
Natural fragrance alternative
Offers a subtle, fresh scent that can reduce the need for synthetic fragrances, which are a common irritant for sensitive skin.
Cons and cautions
Limited research
Most studies focus on lemon fruit or peel; specific research on the flower/leaf/stem extract is sparse, so its efficacy is less established than other antioxidants.
Potential allergen
While rare, citrus-derived ingredients can cause allergic reactions in sensitive individuals, so patch testing is recommended for new users.
Best for
- Anyone looking for a gentle antioxidant ingredient in their skincare routine
- People who prefer products with natural botanical extracts
Use caution if
- Individuals with a known allergy to citrus plants or specific sensitivity to botanical extracts
