Ingredient review
Hydrolyzed Sturgeon Ovary Membrane Extract
INCI: Hydrolyzed Sturgeon Ovary Membrane Extract
A luxurious, protein-rich extract that helps hydrate and condition skin, but scientific evidence is limited and it may not be suitable for strict vegans.
In plain English
This ingredient is made from the membrane of sturgeon fish eggs (caviar). It's broken down into smaller pieces (hydrolyzed) so it can be absorbed by skin. Think of it as a fancy, fish-derived protein that helps your skin hold onto moisture and feel smoother. It's often found in high-end anti-aging products because of its association with luxury, but it's not a miracle worker.

Quick decision guide
Useful, but context matters
Hydrolyzed Sturgeon Ovary Membrane Extract is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Hydrolyzed Sturgeon Ovary Membrane Extract.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A hydrolyzed protein extract from the membrane that surrounds sturgeon eggs (caviar). Hydrolysis breaks the proteins into smaller peptides and amino acids, which are more easily absorbed by the skin.
How it works
The small peptides and amino acids in this extract act as humectants, drawing moisture into the skin. They also help support the skin's natural barrier function, reducing water loss and leaving skin feeling softer and more supple. Some amino acids may also have antioxidant properties.
Pros
Intense hydration
The amino acids and peptides act as humectants, drawing moisture into the skin and helping it stay hydrated throughout the day.
Skin barrier support
By providing building blocks for skin proteins, it may help strengthen the skin's natural barrier, reducing moisture loss and improving resilience.
Cons and cautions
Limited scientific backing
Most evidence for caviar extracts is anecdotal or from small studies. There are no large-scale, peer-reviewed human trials proving its superiority over other protein-based humectants.
Not vegan-friendly
Since it is derived from fish, it is not suitable for anyone following a vegan or vegetarian lifestyle, which may limit its appeal.
Best for
- People with dry or dehydrated skin
- Those looking for a luxury, protein-rich moisturizing ingredient
Use caution if
- Strict vegans and vegetarians
- Individuals with fish allergies (though risk is low due to high processing)
Usage tips
Safety summary
Hydrolyzed Sturgeon Ovary Membrane Extract is considered safe for topical use with a low risk of irritation or allergic reaction. As with any protein-based ingredient, individuals with severe fish allergies should exercise caution, though the hydrolysis process significantly reduces allergenic potential.
Research notes
Research on this specific ingredient is limited. Most evidence comes from studies on hydrolyzed fish proteins in general, which show humectant and skin-conditioning benefits. No large-scale clinical trials specifically on sturgeon ovary membrane extract are available.
Common label clues
- Typical concentration
- 0.1% to 1% in finished products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used at typical concentrations. No specific restrictions beyond standard cosmetic ingredient regulations.
- Common uses
- Anti-aging serums, Luxury moisturizers, Eye creams
- Environmental note
- Sturgeon are often farmed for caviar, and using the membrane byproduct may reduce waste. However, overfishing of wild sturgeon is a concern; look for sustainably sourced versions.
Good to know
- The 'hydrolyzed' process breaks down large proteins into smaller peptides, making them more absorbable by the skin.
- This ingredient is often marketed as 'caviar extract' and is a hallmark of luxury skincare lines.
