What it is
A cell extract from Prorocentrum micans, a single-celled marine organism (dinoflagellate) known for its bioluminescence. It contains various bioactive compounds like amino acids, sugars, and antioxidants.
How it works
The extract is thought to stimulate the skin's natural defense mechanisms, including antioxidant enzymes, to neutralize free radicals. It may also help reduce inflammation and support collagen production, though the exact pathways are still being studied.
Pros
Gentle antioxidant
Provides a mild antioxidant boost without irritation, making it suitable for sensitive skin types.
Soothing properties
May help calm redness and inflammation, offering comfort for reactive skin.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so the real-world benefits are not fully proven.
Potential allergen
As a marine-derived ingredient, it could trigger allergies in people sensitive to seafood or ocean organisms.
Best for
- People with dull or tired-looking skin
- Those looking for extra antioxidant protection in their routine
Use caution if
- Individuals with known allergies to marine organisms or plankton
