WHEY FERMENT

About WHEY FERMENT

A fermented whey ingredient — brings peptides, amino acids, and mild lactic acid to skincare. Generally gentle; dairy-allergy caveat.

Detailed Analysis

Whey Ferment is the fermentation product of whey, the liquid fraction remaining after cheese production. Fermentation (often by lactic-acid bacteria like Lactobacillus) converts lactose into lactic acid and generates bioavailable peptides and amino acids. In cosmetics it functions as a humectant, mild exfoliant (via lactic acid), and skin conditioning agent. Food-grade parent material gives strong baseline safety; the ingredient is well-tolerated at typical cosmetic concentrations (1-10%). Dairy allergens can persist depending on processing; declaration may be required in allergen-aware regulatory frameworks. No dedicated CIR review under this exact INCI.
