Polygonum Odoratum Extract

Polygonum odoratum extract is derived from Vietnamese coriander (also known as rau răm), a herbaceous plant used in traditional Asian cuisine and skincare. The extract is obtained from the leaves and stems, which are rich in compounds including flavonoids and phenolic acids.In skincare, it functions as a skin conditioner, helping to soften and smooth the skin surface. It is typically incorporated into formulations at low concentrations and is generally recognised as a mild, plant-derived ingredient suitable for topical use.

The extract contains bioactive compounds, particularly flavonoids, which are thought to work through multiple pathways. These compounds may help improve skin hydration by supporting the skin barrier function and reducing water loss. They may also provide antioxidant activity, helping to neutralise free radicals that can contribute to skin ageing.At a practical level, the extract also functions as a humectant and emollient, helping to draw moisture into the skin and seal it in, which contributes to its skin-conditioning effect.

As a skin-conditioning ingredient, Polygonum odoratum extract is typically incorporated into serums, moisturisers, toners, and treatment products. It is generally well-tolerated and can be used as part of a daily skincare routine. Apply to clean skin and follow with other products as needed. Since it is usually present at low concentrations, it works best as part of a broader skincare strategy rather than as a standalone treatment.

Polygonum odoratum extract is generally well-tolerated and considered safe for topical use. Those with known sensitivity to plants in the Polygonaceae family should patch-test first.
