What Is Pachyrhizus Erosus Seed Extract?
Pachyrhizus Erosus Seed Extract comes from the seeds of Pachyrhizus erosus, a climbing vine in the bean family better known as jicama or yam bean. While most people know jicama for its crisp edible root, the seeds have long held a place in traditional beauty rituals across parts of Central America and Asia where the plant grows. The seeds are rich in proteins, starches and natural sugars, plus small amounts of minerals and flavonoids, all of which can help soften and smooth skin when used topically.
To create the extract, dried seeds are cleaned, ground and soaked in a food grade solvent such as water or a mix of water and glycerin. The liquid pulls out the skin friendly compounds and is then filtered and gently heated to remove excess solvent, leaving a concentrated plant extract. Cosmetic chemists may further refine or standardize the extract so each batch performs the same in a formula.
You will most often spot Pachyrhizus Erosus Seed Extract in hydrating sheet masks, soothing creams, lightweight gel moisturizers and after sun products. Brands include it in anti aging serums too because its natural sugars can form a light film on the skin that helps lock in moisture giving a plumper appearance.

Who Can Use Pachyrhizus Erosus Seed Extract
Pachyrhizus Erosus Seed Extract is generally suitable for all skin types. Its light, water-binding sugars make it a welcome addition for dry or mature skin seeking extra hydration while its non-oily texture works well for combination and oily complexions that dislike heavy creams. Sensitive skin usually tolerates it because the extract is mild and free of common irritants, though anyone with a known legume allergy should approach with caution since jicama belongs to the bean family.
The ingredient is plant derived with no animal by-products involved in harvesting or processing so it is appropriate for vegans and vegetarians.
No published data suggests problems for women who are pregnant or breastfeeding when the extract is used topically at cosmetic levels. This is not medical advice and expectant or nursing mothers should run any skincare product past a qualified healthcare professional to be safe.
Pachyrhizus Erosus Seed Extract is not known to increase photosensitivity. Standard daytime sun protection habits remain sufficient when using products that include it.

Comedogenic Rating
Rating: 0–1. Pachyrhizus Erosus Seed Extract is a water-soluble plant extract that contains mostly sugars, proteins and trace minerals rather than heavy oils or waxes that can clog pores. Because it sits lightly on the skin and is typically used at low percentages, it is considered non-comedogenic to very low comedogenic.
Suitable for acne-prone and breakout-prone skin as it hydrates without adding pore-blocking residue.
No studies link the extract to increased sebum production or blackhead formation. Formulas that combine it with richer oils or butters could change the overall pore-clogging potential, so always consider the full ingredient list.

It is still a niche ingredient rather than a mainstream superstar, but its presence is growing in sheet masks, lightweight gels and calming moisturizers thanks to its plant-based appeal and adaptable texture.
Topical use is regarded as safe for all skin types with only rare allergy concerns tied to legumes. Even so, skin is unique, so perform a quick patch test whenever you add a new product that features this extract.
