Ingredient review
Green Bean Callus Extract
INCI: Phaseolus Vulgaris (Kidney Bean) Callus Extract
A gentle, plant-derived antioxidant that may help calm skin and protect against environmental stress, though research is still early.
In plain English
This ingredient is made from the callus cells of the common kidney bean (Phaseolus vulgaris). Callus cells are undifferentiated plant cells grown in a lab from a small sample of the plant. They are rich in protective compounds like flavonoids and peptides. In skincare, this extract is thought to help neutralize free radicals (unstable molecules that can damage skin) and provide a mild soothing effect. Because it comes from a food plant and is produced in a controlled lab setting, it is considered a sustainable and gentle option for antioxidant skincare.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A cosmetic ingredient produced by cultivating undifferentiated plant cells (callus) from the kidney bean in a sterile lab environment. The resulting extract contains a concentrated blend of the plant's natural protective metabolites, including flavonoids, phenolic acids, and small peptides.
How it works
The extract delivers antioxidant compounds that can neutralize free radicals generated by UV exposure and pollution. It may also support the skin's natural repair processes by providing building blocks (like amino acids) and signaling molecules that encourage a calm, balanced complexion.
Pros
Gentle antioxidant
Provides free-radical protection without the irritation sometimes seen with stronger antioxidants, making it suitable for sensitive or reactive skin.
Sustainable sourcing
Produced from lab-cultured plant cells rather than whole plants, reducing agricultural impact and ensuring a consistent, pure extract.
Cons and cautions
Limited research
Most evidence comes from lab or early-stage studies; there are few published human trials confirming its benefits for aging or pigmentation.
Potential allergen
As a legume-derived ingredient, it may cause a reaction in people with bean or peanut allergies, though this is rare in topical use.
Best for
- Anyone looking for a gentle, plant-based antioxidant suitable for sensitive skin
- Those interested in sustainable, lab-grown skincare ingredients
Use caution if
- Individuals with a known allergy to legumes (beans) should patch test first
Usage tips
Safety summary
Green Bean Callus Extract is considered safe for topical use at typical concentrations. It has a low irritation and comedogenic risk. As with any plant-derived ingredient, patch testing is recommended for those with legume allergies.
Research notes
Research on Phaseolus vulgaris callus extract is in early stages. In vitro studies show antioxidant and anti-inflammatory activity, but well-controlled human trials are lacking. The ingredient is promising but not yet backed by strong clinical evidence.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets as a safe botanical ingredient. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Serums, Moisturizers, Eye Creams
- Environmental note
- Lab-grown callus extracts reduce the need for land, water, and pesticides compared to traditional farming, supporting a lower environmental footprint.
Good to know
- Callus culture technology allows for year-round production without harvesting whole plants, making it a more sustainable choice.
- The extract is typically water-soluble and works well in gel or lightweight lotion formulations.
