What it is
Hydrolyzed lupine protein consists of peptides and amino acids produced by enzymatic or acid hydrolysis of protein from lupin (Lupinus) seeds. In leave-on and rinse-off formulas it is included for its skin-conditioning and surface film-forming properties, which can give a smoother feel to the skin. It is typically used at low concentrations as a botanical functional additive rather than as a primary structural component.
Safety & warnings
As a hydrolyzed legume protein it is generally well tolerated topically. Because lupin is a legume botanically related to peanut and other legumes, individuals with legume allergies may wish to use caution, though topical reactions are uncommon. It is not a recognized fragrance allergen and is not an oil, so comedogenicity is not a typical concern.
Origin & sourcing
Plant-derived. It is made by hydrolyzing the storage protein of lupin seeds, a legume, into a mixture of lower-molecular-weight peptides and amino acids.
Questions everyone asks
What is hydrolyzed lupine protein made from?
It is made from the seed protein of lupin, a legume, which is broken down by hydrolysis into smaller peptides and amino acids for use as a skin-conditioning ingredient.
What does it do in a sunscreen?
It acts as a skin-conditioning and film-forming additive that can improve skin feel; it is not a UV filter and does not provide sun protection on its own.
