Science
Mechanism of Action
This ingredient functions primarily as a sophisticated skin conditioning agent. Hydrolyzed salmon roe proteins operate through an enzymatic action, carefully breaking down cell adhesions on the skin's surface to facilitate exfoliation. This mechanism offers a potentially less irritating alternative to traditional acid-based exfoliants, while simultaneously enhancing skin hydration and overall moisturization.

Specific optimal pH for Hydrolyzed Roe stability was not identified; however, most cosmetic formulations are designed for a pH range of 4-6 to ensure both product stability and skin compatibility.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not explicitly reviewed 'Hydrolyzed Roe' but has deemed other hydrolyzed proteins and peptides derived from skin and connective tissues safe. However, CIR notes that fish proteins are recognized food allergens capable of eliciting Type I hypersensitivity reactions upon ingestion. Therefore, individuals with pre-existing fish allergies should exercise caution as topical exposure to fish-derived ingredients may trigger a reaction. Despite this, EWG Skin Deep rates Hydrolyzed Roe with a 'LOW' hazard for cancer, allergies & immunotoxicity, developmental and reproductive toxicity, and use restrictions, and it is not on their restricted or unacceptable lists.
