Ingredient review
Lake Whitefish Extract
INCI: COREGONUS CLUPEAFORMIS EXTRACT
A novel marine-derived extract that may help hydrate and condition skin, but research is limited and it's not a proven powerhouse.
In plain English
This ingredient is an extract from lake whitefish, a type of freshwater fish. In skincare, it's added to products like moisturizers and serums to help keep skin feeling soft and hydrated. Think of it as a gentle, natural skin conditioner that may support the skin's moisture barrier, though it's not as well-studied as more common ingredients like glycerin or hyaluronic acid.

What it is
A natural extract obtained from the tissues of Coregonus clupeaformis, commonly known as lake whitefish. It contains proteins, amino acids, and other bioactive compounds that may benefit the skin.
How it works
The extract is thought to provide skin-conditioning benefits by delivering amino acids and peptides that can help maintain skin hydration and support the skin's natural barrier function. It may also have mild antioxidant properties, though the exact mechanisms are not fully characterized.
Pros
Natural origin
Derived from a renewable freshwater fish source, appealing to consumers seeking naturally-sourced ingredients.
Potential hydration support
May help improve skin moisture levels due to its amino acid content, which can attract and hold water in the skin.
Cons and cautions
Limited research
There are very few peer-reviewed studies on this specific extract, so its benefits are not well-established compared to more common humectants.
Allergen risk
As a fish-derived ingredient, it poses a risk of allergic reaction for individuals with fish allergies, which is a significant safety consideration.
Best for
- Those looking for novel, natural ingredients
- People with dry or dehydrated skin seeking extra hydration
Use caution if
- Individuals with known fish allergies
- Those who prefer ingredients with strong clinical evidence
