Hydrolysed Vegetable Protein
INCI: Hydrolyzed Vegetable Protein
Small plant-protein fragments that adsorb to the lash surface and form a conditioning film, helping smooth the cuticle so stressed fibres look less frayed and brittle.
Evidence and limitations
Hair-science literature shows hydrolysed proteins adsorb to and partly penetrate keratin fibres to improve condition and reduce breakage; equivalent independent peer-reviewed evidence specific to eyelashes is limited.
