What Is Brassica Rapa Leaf Extract?
Brassica rapa leaf extract is derived from turnip greens, a cruciferous vegetable rich in polyphenols, vitamins, and minerals. In skincare formulations, it functions as a skin conditioning agent, meaning it helps improve the texture, feel, and appearance of the skin surface.
The extract contains compounds that may help support the skin's natural moisture balance and overall skin health, though it is typically used as a supporting ingredient rather than a primary active.
How It Works
Brassica rapa leaf extract works primarily as a humectant and conditioning agent. The polyphenols and minerals present in the extract help to draw moisture into the outer layers of the skin whilst also creating a protective film that reduces transepidermal water loss.
The antioxidants within the extract may also help neutralise free radicals generated by environmental exposure, though the extent of this benefit in a cosmetic formulation will depend on the concentration used and the stability of the extract.
Clinical Evidence & References
Published clinical research specifically on brassica rapa leaf extract in skincare is limited. Most evidence is derived from the known composition of the ingredient — its polyphenol and mineral content — rather than dedicated human studies of the finished ingredient in cosmetic products.
The ingredient is generally recognised as safe and well-tolerated in skincare formulations. Further research would help clarify its efficacy at typical cosmetic concentrations.
How to Use
Brassica rapa leaf extract is typically used as a supporting ingredient in serums, moisturisers, and essences. It can be used daily as part of your regular skincare routine. Combine it with other conditioning and hydrating ingredients for cumulative benefits to skin texture and comfort.
