Ingredient review
Jicama Root Extract
INCI: Pachyrhizus erosus root extract
Jicama root extract is a gentle, hydrating ingredient with antioxidant potential, but research on its cosmetic benefits is still limited.
In plain English
Jicama root extract comes from the root of the jicama plant, a crunchy vegetable often eaten in salads. In skincare, it's used mainly for its water-binding ability (it helps your skin hold onto moisture) and for providing some antioxidant protection against environmental stressors. Think of it as a mild, plant-based helper that supports your skin's hydration without causing irritation.

What it is
Jicama root extract is a water-soluble extract derived from the tuberous root of Pachyrhizus erosus, a legume native to Mexico and Central America. It contains natural sugars, inulin (a prebiotic fiber), and vitamin C, which contribute to its moisturizing and antioxidant properties.
How it works
When applied to the skin, jicama root extract acts as a humectant, drawing water from the environment and deeper layers of the skin to the surface, helping to keep the skin plump and hydrated. Its antioxidant compounds, including vitamin C, help neutralize free radicals that can cause premature aging. The inulin content may also support the skin's natural microbiome by acting as a prebiotic.
Pros
Gentle hydration
Jicama root extract provides moisture without clogging pores or feeling heavy, making it suitable for most skin types, including sensitive skin.
Antioxidant support
The natural vitamin C content helps protect skin from oxidative stress caused by pollution and UV exposure, though it is not a substitute for sunscreen.
Cons and cautions
Limited research
Most evidence for jicama root extract's skincare benefits comes from traditional use and basic lab studies, not large-scale human trials, so its efficacy is not fully proven.
Potential allergen
As a legume-derived ingredient, it may cause allergic reactions in people with legume allergies, though such reactions are rare in topical use.
Best for
- People with dry or dehydrated skin looking for a gentle humectant
- Those who prefer plant-based, natural ingredients in their routine
Use caution if
- Individuals with known allergies to legumes (jicama is a legume) should patch test first
Usage tips
Safety summary
Jicama root extract is considered safe for topical use with a low risk of irritation or clogging pores. As with any new ingredient, patch testing is recommended, especially for those with legume allergies.
Research notes
Research on jicama root extract in cosmetics is preliminary. Studies have shown antioxidant and humectant properties in vitro, but human clinical data is scarce. Its traditional use as a food suggests good tolerability.
Common label clues
- Typical concentration
- 0.5% to 5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU, with no specific restrictions beyond standard cosmetic safety requirements.
- Common uses

- Environmental note
- Jicama is a sustainable crop that grows well in tropical regions, and its root is a byproduct of the food industry, making the extract a relatively eco-friendly ingredient.
Good to know
- Jicama root extract is often listed as Pachyrhizus erosus root extract on ingredient labels.
- It is sometimes used in combination with other humectants like glycerin for enhanced moisturizing effects.
