What Is Polygonum Multiflorum Extract?

Polygonum multiflorum extract is derived from the root of Polygonum multiflorum, a plant used in traditional Chinese medicine. The extract is rich in compounds with antioxidant activity, which help neutralise free radicals that accumulate in the skin from environmental stressors like UV exposure.

In skincare formulations, this ingredient functions as a skin conditioner, helping to support the skin's natural defences against oxidative stress and environmental damage.

How It Works

The extract contains compounds that work as antioxidants, meaning they donate electrons to neutralise free radicals before they can damage skin cells and collagen. This helps reduce oxidative stress, a key mechanism in photoaging and skin damage.

Research suggests the extract may also support cellular energy production and protective glutathione pathways, which are part of the skin's own defence system against oxidative damage.

Clinical Evidence & References

In vitro studies show that Polygonum multiflorum extract demonstrates antioxidant capacity and can reduce oxidative stress in human skin cells exposed to hydrogen peroxide. Research using nanovesicles derived from the plant suggests potential benefits in combating UV-induced photoaging by alleviating oxidative stress.

However, most evidence to date comes from laboratory and cell-based studies rather than human clinical trials. Whilst the findings are promising, further research in human subjects would help establish the practical efficacy of this ingredient in skincare products at typical cosmetic concentrations.

How to Use

Polygonum multiflorum extract is typically incorporated into serums, essences and moisturisers at low concentrations. It works well as part of a broader antioxidant regimen, particularly when combined with other protective ingredients like vitamin E or niacinamide. Use daily as part of your regular skincare routine.

Safety & Precautions

Polygonum multiflorum extract is generally well-tolerated in cosmetic formulations. Those with known sensitivity to plants in the Polygonaceae family should patch test first.
