What Is Bergamot … Ferment Extract?

Citrus fruit ferment extracts are derived from bergamot, grapefruit, orange, or tangerine that have undergone fermentation. This process breaks down the fruit's cell walls and can modify its chemical composition, potentially increasing the bioavailability of beneficial compounds like flavonoids and other polyphenols.

In skincare formulations, these extracts function primarily as antioxidants, helping to neutralise free radicals that can contribute to oxidative stress on the skin.

Benefits for Your Skin

How It Works

Fermented citrus extracts contain polyphenols and flavonoids that act as antioxidants. These compounds donate electrons to free radicals, stabilising them and preventing them from damaging skin cells and collagen.

The fermentation process may enhance the extraction and stability of these beneficial compounds, though the extent to which fermentation improves efficacy compared to non-fermented citrus extracts remains unclear from publicly available research.

Clinical Evidence & References

Research specifically on fermented citrus fruit extracts in skincare is limited. However, citrus-derived polyphenols are recognised in scientific literature for their antioxidant properties in vitro. Whether these benefits translate meaningfully to skin when applied topically depends on several factors, including concentration, formulation stability, and skin penetration.

Fermented versions may offer improved stability or bioavailability compared to standard extracts, but direct comparative studies in human subjects are sparse. These ingredients are generally considered supportive rather than primary actives in a skincare routine.

How to Use

Fermented citrus extracts are typically found in serums, essences, and moisturisers as part of a broader formula. Use according to your product's instructions. These ingredients work well alongside other antioxidants (such as vitamin C or niacinamide) and are compatible with most skincare routines. If introducing a product containing this extract, apply it after cleansing and before heavier creams.

Safety & Precautions

Citrus ferment extracts are generally well-tolerated. However, citrus ingredients can occasionally cause sensitivity or photosensitivity in some individuals; if you have known citrus sensitivity or are prone to reactions, patch-test first.
