Ingredient review
Cudrania Callus Extract
INCI: CUDRANIA TRICUSPIDATA CALLUS CULTURE EXTRACT
A lab-grown plant antioxidant that may help protect skin from environmental stress, but human studies are still limited.
In plain English
This ingredient is made by growing cells from the Cudrania tricuspidata plant (also known as mandarin melon) in a lab. The cells are harvested and processed to create an extract rich in antioxidants. In skincare, it's used to help defend the skin against damage from pollution and UV exposure, and to calm irritation. Because it's produced in a controlled lab environment, it's more sustainable and consistent than harvesting the whole plant.

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 biotech-derived extract from the callus (undifferentiated plant cells) of Cudrania tricuspidata, a tree native to East Asia. The extract contains flavonoids and phenolic compounds with antioxidant activity.
How it works
The antioxidant compounds in the extract neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It may also help reduce inflammation by calming the skin's immune response to irritants.
Pros
Sustainable sourcing
Because it's grown in a lab from plant cells, it doesn't require harvesting the whole plant, making it an eco-friendly choice.
Gentle antioxidant
It offers antioxidant benefits without the irritation that some stronger antioxidants (like pure vitamin C) can cause, making it suitable for sensitive skin.
Cons and cautions
Limited human research
Most evidence comes from lab studies; there aren't many human trials proving it outperforms well-established antioxidants.
Premium price
The biotech production process is more expensive, which can make products containing this ingredient pricier.
Best for
- People looking for antioxidant protection in a gentle, non-irritating form
- Those interested in sustainable, biotech-derived skincare ingredients
Use caution if
- Anyone with a known allergy to Cudrania tricuspidata or related plants (rare)
Usage tips
Safety summary
Cudrania tricuspidata callus culture extract is considered safe for topical use. It has low irritation and comedogenic potential, making it suitable for most skin types. As with any new ingredient, patch testing is recommended for those with very sensitive skin or plant allergies.
Research notes
Research is primarily in vitro (lab studies) showing antioxidant and anti-inflammatory activity. Human clinical studies are scarce, so the evidence level is emerging. More studies are needed to confirm its efficacy compared to established antioxidants.
Common label clues
