What Is Phaseolus Lunatus Seed Extract?

Phaseolus lunatus seed extract is derived from lima beans, a legume native to Central and South America. The extract is obtained from the seeds and contains compounds that function as an emollient—a substance that softens and smooths the skin surface by helping to retain moisture.

In skincare formulations, this ingredient is used primarily to improve skin feel and texture. It works by forming a light barrier on the skin that reduces transepidermal water loss, helping to maintain hydration levels without a heavy or occlusive finish.

How It Works

Lima bean seed extract functions as an emollient by forming a thin, protective layer on the skin's surface. This layer helps to seal in existing moisture and prevent water from evaporating into the environment—a process called transepidermal water loss (TEWL).

The plant compounds present in the extract have mild conditioning properties that smooth the skin's outer layer, which can improve both texture and the overall feel of the skin without occluding pores or creating a greasy sensation.

Clinical Evidence & References

Published research on phaseolus lunatus seed extract specifically in skincare is limited. Most evidence supporting its use comes from its known chemical composition and traditional use in cosmetic formulations rather than extensive clinical trials.

The ingredient is generally recognised as safe in cosmetic use, though like all legume-derived ingredients, it may present cross-reactivity risks for individuals with pollen allergies or specific legume sensitivities. More targeted clinical studies would help establish specific efficacy claims for this ingredient.

How to Use

This ingredient is typically used as part of a broader skincare formulation rather than as a standalone treatment. It works well in moisturisers, serums, and conditioning products. As with any new product, patch test first if you have known plant sensitivities or legume allergies.

Safety & Precautions

Generally well-tolerated in cosmetic formulations. However, individuals with pollen allergies or legume sensitivities should exercise caution, as there is potential for cross-reactivity.
