Rheum Palmatum Root Extract

Rheum palmatum root extract is derived from the rhizome of the rhubarb plant, a traditional ingredient in Asian skincare with a history spanning centuries. The extract is rich in phenolic compounds, which give it antioxidant properties. In cosmetic formulations, it functions as an astringent and skin conditioning agent.The extract works by delivering antioxidants to the skin, helping to neutralise free radicals and support the skin's natural defences against environmental stressors.

The phenolic compounds in rhubarb root extract function as antioxidants, meaning they can donate electrons to unstable free radical molecules and render them harmless. This process helps reduce oxidative stress within the skin, which is implicated in both acute UV damage and long-term skin ageing.Additionally, research indicates the extract may influence melanin production pathways and inflammatory signalling in skin cells exposed to UV radiation, though the full mechanisms in living human skin require further investigation.

Rhubarb root extract is typically found in serums, essences, and sunscreen formulations. Use as directed on the product label. For sunscreen applications, apply generously and reapply every two hours or after swimming. Combine with broad-spectrum SPF during the day for comprehensive UV protection. There is no evidence of irritation at typical cosmetic concentrations, so it can generally be incorporated into both morning and evening routines.

Rhubarb root extract is generally well-tolerated in topical skincare products. No major safety concerns have been identified at cosmetic concentrations, though sensitivity remains possible in individuals with known plant allergies.
