What it is
A powdered ingredient produced from callus (undifferentiated plant cells) of blackcurrant (Ribes nigrum) buds, cultivated in a sterile lab setting to preserve active compounds.
How it works
The callus cells are rich in polyphenols and anthocyanins, which act as antioxidants. When applied to skin, these compounds help neutralize free radicals generated by UV rays and pollution, potentially reducing oxidative stress and supporting the skin's natural repair processes.
Pros
Gentle antioxidant
Provides antioxidant protection without the irritation that some stronger antioxidants can cause, making it suitable for sensitive skin.
Sustainable sourcing
Produced from lab-grown plant cells, this ingredient avoids harvesting whole plants, reducing environmental impact.
Cons and cautions
Limited research
Most evidence comes from lab studies; there are few human clinical trials confirming its benefits on skin.
Higher cost
The biotech production process makes this ingredient more expensive, which can increase the price of finished products.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- People with sensitive skin who react to stronger antioxidants like pure vitamin C
Use caution if
- Individuals with a known allergy to blackcurrants or related berries
Usage tips
