What it is
A natural extract derived from Nostochopsis lobatus, a species of blue-green algae found in freshwater environments. It is rich in polysaccharides, amino acids, and antioxidant compounds.
How it works
The polysaccharides in the extract form a thin film on the skin that helps lock in moisture, while its antioxidant content neutralizes free radicals that can cause premature aging. It also supports the skin's natural barrier function.
Pros
Gentle hydration
The polysaccharides in this algae extract help attract and hold moisture to the skin's surface without feeling sticky or heavy, making it suitable for daily use.
Antioxidant support
It contains natural antioxidants that help neutralize free radicals from pollution and UV exposure, potentially reducing signs of aging over time.
Cons and cautions
Limited research
Most evidence comes from lab studies or ingredient supplier data; there are few independent human trials confirming its benefits in real-world skincare.
Lower potency
Compared to established humectants like hyaluronic acid or glycerin, this extract may provide less dramatic hydration, especially for very dry skin.
Best for
- Anyone seeking extra hydration without heavy oils
- Sensitive skin types looking for a gentle antioxidant
Use caution if
- Those allergic to algae or seaweed-derived ingredients
