What Is Phaseolus Vulgaris Seed Extract?

Phaseolus vulgaris seed extract is derived from the common kidney bean, a legume widely cultivated and valued for its nutritional profile. The extract is obtained through concentration of ethanolic extracts from the bean seeds, capturing the plant's naturally occurring antioxidant compounds.

In skincare formulations, this ingredient functions as a skin conditioning agent. Its primary role centres on delivering antioxidant activity to the skin, which may help counteract oxidative stress and support the skin's natural defences.

How It Works

The extract contains bioactive compounds capable of scavenging free radicals—unstable molecules generated by UV exposure, pollution and normal metabolism. These free radicals can degrade collagen and elastin, accelerating visible signs of ageing. By neutralising them, the extract may reduce oxidative damage to skin cells.

Additionally, preliminary research indicates the extract may help modulate skin proteins associated with collagen breakdown (such as matrix metalloproteinases), potentially slowing the breakdown of skin structure and maintaining firmness.

Clinical Evidence & References

Laboratory studies using cultured human skin cells (keratinocytes) exposed to UVB radiation have shown that Phaseolus vulgaris seed extract demonstrates measurable antioxidant activity and can reduce markers of photodamage. These findings suggest the ingredient has genuine bioactivity relevant to skin ageing.

However, human clinical evidence remains limited. One small double-blind study on eye wrinkle appearance showed promise, but larger, well-controlled trials are needed to establish efficacy in real-world use. The ingredient shows potential, but evidence for visible anti-ageing benefits in human skin is still emerging.

How to Use

This ingredient is typically incorporated into creams and emulsified formulations rather than serums or essences. Apply to clean skin as part of your regular skincare routine. It works well alongside other antioxidants and can be used both morning and evening, though consistency over time is more important than frequency for antioxidant benefits to accumulate.

Safety & Precautions

Phaseolus vulgaris seed extract is generally well-tolerated. As with any plant-derived ingredient, those with known legume sensitivities should patch test first.
