What it is
A natural extract obtained from the protective mucus layer on the skin of sturgeon fish, rich in glycoproteins, peptides, and polysaccharides that help retain moisture.
How it works
The extract forms a thin, moisturizing film on the skin's surface, reducing water loss (transepidermal water loss, or TEWL) and providing a soothing effect. Its peptides may also support the skin's natural barrier function.
Pros
Hydrating film
Creates a light, moisturizing layer on skin that helps lock in moisture without feeling heavy.
Soothing potential
May help calm irritated or sensitive skin, making it a good option for gentle skincare routines.
Cons and cautions
Limited research
Most evidence is anecdotal or from early studies; there are few peer-reviewed human trials confirming its benefits.
Not vegan-friendly
Derived from sturgeon fish, so it is unsuitable for vegans and those with fish allergies.
Best for
- People with dry or dehydrated skin looking for extra hydration
- Those with sensitive skin seeking a gentle, soothing ingredient
Use caution if
- Individuals with known fish allergies
- Vegans or those avoiding animal-derived ingredients
