What it is
A cosmetic ingredient produced by cultivating callus cells (undifferentiated plant cells) from the green algae Halimeda bikiniensis in a controlled laboratory environment. This biotech approach ensures sustainability and consistency.
How it works
It is thought to work by providing polysaccharides and other compounds that help bind water to the skin's surface, reducing water loss. It may also have mild anti-inflammatory effects, calming redness or sensitivity.
Pros
Sustainable sourcing
Lab-grown from algae cells, so no wild harvesting is needed, making it an eco-friendly choice.
Gentle hydration
Helps skin retain moisture without feeling sticky or heavy, suitable for daily use.
Cons and cautions
Limited research
Most evidence comes from lab studies or small trials; large-scale human studies are lacking.
Higher cost
The biotech production process can make products with this ingredient pricier than those with common humectants.
Best for
- People with dry or dehydrated skin
- Those with sensitive or easily irritated skin
Use caution if
- Individuals with known algae allergies (though rare, patch test first)
