Hydrolyzed Milk Protein
Explained
Hydrolyzed Milk Protein is milk protein that has been broken down into smaller peptide fragments and amino acids. It has skin conditioning properties.
One manufacturer study found Hydrolyzed Milk Protein increased skin hydration immediately and cumulatively in rinse-off applications.
The most robust research comes from the individual milk protein components; a 2023 study found whey proteins stimulated fibroblasts to produce more collagen I, elastin, and glycosaminoglycans while protecting skin from breaking down.
Be sure to avoid or patch test if you have a dairy allergy.
