What Is Bidens Pilosa Extract?

Bidens pilosa extract comes from a tropical plant traditionally used in various cultures. In skincare formulations, it functions as a humectant—a substance that helps draw moisture into the skin—and is used for general skin conditioning purposes.

The extract contains bioactive compounds that research suggests may have antiviral and antioxidant properties, though its use in cosmetics remains relatively niche, appearing in fewer than 1% of skincare products currently available.

How It Works

As a humectant, Bidens pilosa extract works by attracting water molecules to the skin's surface and upper layers, helping to maintain hydration levels. This mechanism is straightforward and well-established in skincare chemistry.

Beyond hydration, laboratory studies indicate the extract may contain compounds with antioxidant properties that could help protect skin cells from environmental damage, though the extent of this benefit in topical formulations remains unclear.

Clinical Evidence & References

In-vitro research has shown that Bidens pilosa extract exhibits antiviral activity in cell cultures, though these laboratory findings have not yet been extensively translated into clinical skincare studies. Animal studies have suggested potential benefits, but human trials investigating its efficacy in cosmetic products are limited.

The ingredient's use in skincare is primarily supported by its humectant and conditioning properties rather than robust clinical evidence. Further research in human subjects would help establish its practical value in anti-ageing or targeted skincare regimens.

How to Use

Bidens pilosa extract is typically incorporated into serums, hydrating toners, and moisturisers. It works well alongside other humectants such as glycerol or hyaluronic acid, and can be used daily as part of your regular skincare routine. As with any new ingredient, introduce it gradually to monitor your skin's response.

Safety & Precautions

Bidens pilosa extract is generally well-tolerated and appears safe for topical use. As with any botanical ingredient, those with known plant sensitivities should patch-test first.
