What it is
A fermented extract derived from Scenedesmus deserticola, a microalgae species known for surviving extreme conditions like high heat and UV radiation. The fermentation process enhances the bioavailability of its natural compounds, such as polysaccharides, amino acids, and antioxidants.
How it works
In a cosmetic product, this extract works by delivering a blend of antioxidants that can help neutralize free radicals, which are unstable molecules that can damage skin cells. Its polysaccharides also form a light film on the skin, helping to retain moisture and support the skin's natural barrier function.
Pros
Gentle antioxidant
Provides a mild antioxidant boost that can help protect skin from daily environmental damage without irritation.
Hydrating support
The polysaccharides in this extract help attract and hold moisture to the skin, improving hydration levels.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; large-scale human trials are lacking, so effectiveness is not fully proven.
Potential allergen
As a natural algae derivative, it may cause a reaction in people with rare algae allergies, though this is uncommon.
Best for
- Anyone looking for a gentle antioxidant ingredient
- People with dry or dehydrated skin seeking extra hydration
Use caution if
- Individuals with known allergies to algae or fermented ingredients
Usage tips
Safety summary
