What it is
Yuzu seed extract is a natural ingredient derived from the seeds of the Citrus junos fruit. It contains flavonoids, vitamin C, and other antioxidant compounds that help neutralize free radicals.
How it works
When applied to the skin, the antioxidants in yuzu seed extract help neutralize unstable molecules called free radicals, which can damage skin cells and accelerate aging. It also supports the skin's natural barrier function, helping to retain moisture and reduce irritation.
Pros
Gentle antioxidant
Yuzu seed extract provides antioxidant benefits without the irritation that some stronger antioxidants can cause, making it suitable for sensitive skin.
Soothing properties
It can help calm redness and irritation, which is especially helpful for those with reactive or easily inflamed skin.
Cons and cautions
Limited research
Compared to well-studied antioxidants like vitamin C or green tea, yuzu seed extract has less published evidence specifically for topical skin benefits.
Potential allergen
As a citrus-derived ingredient, it may trigger allergic reactions in people with citrus allergies, though this is rare.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- People with sensitive or reactive skin who want protection without irritation
Use caution if
