What it is
A biotechnologically produced extract derived from the callus (undifferentiated cell mass) of Camellia sinensis, the same plant that gives us green, black, and white tea. It contains polyphenols, amino acids, and other bioactive compounds similar to those found in tea leaves.
How it works
The extract delivers antioxidants like catechins that neutralize free radicals, helping to prevent oxidative stress on the skin. It also supports skin barrier function and may reduce inflammation by calming irritated skin cells.
Pros
Sustainable sourcing
Produced from lab-grown cells, this extract doesn't require harvesting tea leaves, reducing agricultural impact and ensuring consistent quality.
Gentle antioxidant
Provides free-radical protection without the potential irritation that some high-concentration antioxidants can cause, making it suitable for sensitive skin.
Cons and cautions
Limited research
Most evidence comes from lab studies or comparisons to whole-leaf tea extracts; there are few human clinical trials specifically on callus culture extract.
Potentially lower potency
Depending on the extraction method, the concentration of active polyphenols may be lower than in traditional green tea leaf extracts.
Best for
- Anyone looking for antioxidant protection in their skincare routine
- People with sensitive or easily irritated skin who want a gentle antioxidant
Use caution if
- Individuals with a known allergy to tea plants (rare)
Usage tips
Safety summary
