Ingredient review
Pleuropterus multiflorus Callus Extract
INCI: PLEUROPTERUS MULTIFLORUS CALLUS CULTURE EXTRACT
A gentle, lab-grown plant extract that may help protect skin from environmental stress and support a more even tone, though research is still early.
In plain English
This ingredient comes from a plant called Pleuropterus multiflorus (also known as Fo-Ti or He Shou Wu in traditional Chinese medicine). Instead of harvesting the whole plant, scientists grow its cells in a lab to create a consistent, sustainable extract. In skincare, it acts as an antioxidant, meaning it helps neutralize unstable molecules called free radicals that can damage skin cells. It may also have soothing properties, making it a candidate for sensitive or stressed skin. However, most of the evidence comes from lab studies or traditional use, not large human trials, so its benefits are promising but not fully proven.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

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 Pleuropterus multiflorus, a plant traditionally used in Chinese medicine. The callus culture method ensures a pure, sustainable supply without harvesting wild plants.
How it works
The extract contains compounds like stilbenes and flavonoids that can scavenge free radicals, reducing oxidative stress on the skin. This may help prevent premature aging and calm irritation. It also appears to support the skin's natural repair processes by promoting collagen production in lab studies.
Pros
Sustainable sourcing
Lab-grown callus culture avoids harvesting wild plants, making it an eco-friendly choice.
Gentle on skin
Low irritation and comedogenic risk, suitable for sensitive skin types.
Cons and cautions
Limited human research
Most evidence comes from lab or traditional use, not large-scale clinical trials on skin.
Lower potency
May not be as powerful as well-studied antioxidants like vitamin C or ferulic acid.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- People with sensitive or reactive skin who want soothing benefits
Use caution if
- Those seeking proven, high-efficacy antioxidants with strong clinical backing
