What Is Rheum Rhabarbarum Extract?

Rheum rhabarbarum extract is derived from rhubarb root and rhizome, a plant with a long history in traditional medicine systems. In skincare, it functions primarily as a skin conditioning agent, helping to maintain skin texture and feel.

The extract contains compounds including anthraquinones and polyphenols, which contribute to its traditional uses. In cosmetic formulations, it is typically used in modest concentrations to support overall skin health and comfort.

How It Works

Rheum rhabarbarum extract works primarily through its polyphenolic and anthraquinone content. These compounds are thought to have mild antioxidant and astringent properties, which may help tone and support skin integrity.

The extract's conditioning effect comes from its ability to help the skin retain moisture and maintain a smooth, resilient feel, rather than through dramatic transformation.

Clinical Evidence & References

Evidence for rheum rhabarbarum extract in skincare is limited and largely traditional. Most published research explores the plant's use in oral medicine rather than topical application, so specific clinical data on skin benefits is sparse.

The antioxidant and antimicrobial properties of rhubarb compounds have been documented in laboratory settings, but translating these findings to real-world skincare outcomes requires further research. It is best viewed as a supporting ingredient rather than a primary active.

How to Use

Rheum rhabarbarum extract is typically found in toners, essences, serums and moisturisers at modest concentrations. It works well in layered routines and can be used daily as part of a broader skincare regimen. Since it is a gentle conditioning agent, it pairs well with other actives and is unlikely to cause interaction concerns.

Safety & Precautions

Rheum rhabarbarum extract is generally well-tolerated and regarded as safe for topical use in cosmetics. Those with known sensitivity to plants in the Polygonaceae family should exercise caution.
