Ingredient review
Tetrabena Algae Extract
INCI: Tetrabena Socialis Extract
A gentle algae extract that may help calm skin and fight free radicals, but research is still early.
In plain English
Tetrabena Socialis is a type of microalgae found in marine environments. When used in skincare, its extract is thought to provide antioxidant benefits (helping protect skin from damage caused by pollution and UV exposure) and soothing effects (calming redness or irritation). Because it's a natural extract, its exact composition can vary, and most of its benefits are based on lab studies rather than large human trials.

What it is
Tetrabena Socialis Extract is a natural ingredient derived from a microalgae species. It contains various bioactive compounds like polysaccharides, amino acids, and pigments that may benefit the skin.
How it works
In a cosmetic product, Tetrabena Socialis Extract works primarily as an antioxidant, neutralizing free radicals that can cause premature aging. It also has potential anti-inflammatory properties, which can help reduce skin redness and sensitivity. The polysaccharides in the extract may also provide light hydration by forming a thin film on the skin.
Pros
Gentle on skin
Low irritation risk makes it suitable for sensitive skin types, including those prone to redness.
Antioxidant support
Helps neutralize free radicals from pollution and UV, which can contribute to premature aging.
Cons and cautions
Limited research
Most evidence comes from lab studies; large-scale human trials are lacking, so benefits are not fully proven.
Potential allergen
As a marine-derived ingredient, it may cause reactions in people with algae or seafood allergies.
