This hydrolyzed soy-derived protein, composed of short peptides and free amino acids, is made for topical formulations. It conditions skin, boosts the sensation of surface hydration, and offers light barrier support, lending a supple finish in lotions, essences, and masks.

Our take
Is Hydrolyzed Soy Protein a Good Ingredient?
Rated Good because it supplies water-binding peptides that help skin feel supple and support surface hydration, with a typically low irritation profile. Clinical backing for strong barrier repair is limited, which is why it earns a Good rating instead of Great.
What it does
Skin Benefits
Helps skin feel cushioned and supple while easing the sensation of dryness. Contributes to a reinforced surface moisture shield for a healthier-feeling complexion.
Where you'll find it

Before you use it
Safety
Generally safe for cosmetic use, though mild irritation or allergic responses can occur, particularly in those with soy allergies. Patch testing is advisable for sensitive users; no common regulatory limitations noted.
