What it is
This ingredient is produced by hydrolyzing the ovary membrane of salmon, which yields smaller, soluble fragments rich in proteins and related biomolecules. It is used in skincare as a conditioning agent intended to support a smooth, supple surface feel. In sunscreen products it serves as a supporting marine-derived ingredient rather than as a UV filter.
Safety & warnings
Marine protein hydrolyzates are generally well tolerated at cosmetic levels, but because this ingredient is derived from fish, individuals with fish or seafood sensitivities may wish to exercise caution and patch test. It is not associated with comedogenicity.
Origin & sourcing
Animal-derived. It is sourced from the ovary membrane of salmon and then hydrolyzed into smaller fragments. Being fish-derived, it is not suitable for vegan formulations.
