What Is Hydrolyzed Rheum Officinale Root Extract?
Hydrolyzed Rheum Officinale Root Extract is derived from rhubarb root, processed into smaller molecular fragments through hydrolysis. This breakdown makes the active compounds more available for absorption into the skin. Rhubarb has been used in traditional skincare practices across East Asia for centuries, valued for its potential protective and conditioning properties.
In modern skincare formulations, this ingredient functions as a skin protectant, working to help maintain skin's resilience and support its barrier function. The extract contains polyphenols and other plant-derived compounds that may help the skin defend itself against environmental stressors.
How It Works
The hydrolyzed form of this extract allows its active compounds to penetrate the skin more effectively than the whole plant material. Once absorbed, polyphenols and other phytochemicals work to neutralise oxidative stress caused by environmental factors such as pollution and UV exposure.
The ingredient also appears to support the skin's own defence systems, helping to reinforce the barrier layer and reduce sensitivity to external irritants. This protective action is thought to occur at a cellular level, though the precise mechanisms in human skin remain an area for further study.
Clinical Evidence & References
Research on Rheum Officinale extracts in skincare is limited, though the plant has a long history of traditional use. Some in vitro and animal studies suggest potential antioxidant and anti-inflammatory activity, but robust clinical trials on this specific hydrolyzed form in human subjects are sparse.
Most evidence for its skin-protective effects comes from the broader category of plant polyphenols and traditional use data rather than dedicated human studies. For now, it is best considered a supportive botanical ingredient rather than one with strong clinical substantiation for specific skin concerns.
How to Use
This ingredient is typically found in serums, essences, and lightweight moisturisers. It works well alongside other antioxidants and barrier-supporting actives such as niacinamide or ceramides. No special application method is required; use it as directed within your chosen formulation, typically in your regular skincare routine.
