What it is
Glycine soja peptide consists of short peptide chains obtained from the proteins of soybean (Glycine soja). These peptides are water-soluble and help condition the skin surface and support hydration. They are used in serums, moisturizers, and sunscreens for a smoothing, conditioning effect.
Safety & warnings
Soy-derived peptides are generally well tolerated in skincare. Because the ingredient originates from soybean, individuals with known soy allergies may wish to exercise caution. It is not a recognized fragrance allergen and is not an oil, so comedogenicity is not a typical concern.
Origin & sourcing
Derived from soybeans (Glycine soja) by breaking down soy protein into smaller peptide fragments.
