A hydrating plant peptide. Safe.
Glycine Soja (Soybean) Peptide is a peptide obtained from soy proteins. In formulas it serves as a care ingredient with a hydrating leaning: the protein fragments help hold water at the surface and give a softer, smoother feel. It shows up in face and eye serums and creams. On efficacy, a realistic read. Soy peptides have reasonable backing as conditioning and hydrating agents, though claims of marked firming should be taken calmly. It works well as a supporting active within a routine rather than as a stand-in for a strong anti-aging treatment. For topical use in pregnancy and breastfeeding there are no risk signals. Systemic absorption of a peptide from the skin surface is minimal, so it can be used in these stages. Tolerance is good. Low irritation and low allergy potential. Anyone with a known soy allergy should take care, though topical sensitization is uncommon. Most people see no reactions.
