What it is
A natural extract derived from the microalgae Neochloris oleoabundans, rich in polysaccharides, proteins, and fatty acids that can benefit the skin.
How it works
It forms a light film on the skin's surface that helps lock in moisture, while its antioxidant compounds may neutralize free radicals caused by UV and pollution. This dual action supports the skin's barrier function and reduces water loss.
Pros

Helps attract and retain moisture in the skin without feeling heavy or sticky, making it suitable for most skin types.
Antioxidant support
Contains compounds that may help protect skin from environmental damage, though more research is needed to confirm the extent.
Cons and cautions
Limited research
Most evidence comes from lab studies or small trials; large-scale human studies are lacking, so benefits are not fully proven.
Potential allergen
Rare but possible allergic reactions in people sensitive to algae or seaweed, so patch testing is wise for first-time users.
Best for
- People with dry or dehydrated skin
- Those looking for a gentle, natural humectant
Use caution if
