Ingredient review
Peanut Rice Callus Extract
INCI: R-PEANUT RICE CALLUS EXTRACT
A plant cell culture extract that may offer antioxidant and soothing benefits, but research is still emerging.
In plain English
This ingredient is made by growing peanut and rice cells in a lab, then extracting the beneficial compounds. It's used in skincare for its potential to calm irritation and fight free radicals, which are unstable molecules that can damage skin. Because it's produced in a controlled environment, it's consistent and sustainable, but there isn't a lot of human research yet to confirm its effects.

What it is
A cosmetic ingredient derived from the callus (undifferentiated plant cells) of peanut and rice plants, cultivated in a laboratory setting. It contains a mix of natural compounds like polyphenols and amino acids from both plants.
How it works
The extract is thought to work by providing antioxidants that neutralize free radicals, and by delivering soothing compounds that may help calm redness or sensitivity. The exact mechanisms are not fully understood, but it's similar to other plant cell culture extracts used in high-end skincare.
Pros
Sustainable production
Lab-grown plant cells don't require harvesting whole plants, making this a more eco-friendly option.
Gentle on skin
With low irritation and comedogenic risk, it's suitable for most skin types, including sensitive skin.
Cons and cautions
Limited research
There are very few peer-reviewed studies on this specific extract, so its benefits are not well-established.
Potential allergen concern
Even though it's highly processed, individuals with peanut allergy should be cautious and patch test before use.
Best for
