Glycerylamidoethyl Methacrylate/Stearyl Methacrylate Copolymer

A synthetic copolymer of glycerylamidoethyl methacrylate (hydrophilic monomer) and stearyl methacrylate (lipophilic monomer). The amphiphilic architecture allows the polymer to function simultaneously as a film-former, viscosity modifier, and mild emulsifier. Appears in Holika Holika's Good Cera ceramide complex formula where it contributes to the stable, lightweight cream texture.

Glycine Max Leaf Extract

Glycine Max Leaf Extract (soybean leaf extract) is derived from the leaves of the soybean plant, which are particularly rich in isoflavones (genistein, daidzein), flavonoids, and phenylpropanoids. The leaf fraction has a notably high antioxidant capacity and is distinct from the more commonly used soy seed extracts (which focus on proteins and phytosterols). In premium Korean skincare it serves as an antioxidant botanical, often included in multi-extract complexes.

Soybean leaf extract is rich in isoflavones (genistein, daidzein) and flavonoids with potent antioxidant activity, protecting skin from UV-induced oxidative stressGenistein is a well-studied isoflavone that inhibits tyrosinase and downregulates melanin synthesis, contributing mild brightening potentialPolyphenolic and phenylpropanoid compounds from the soybean leaf fraction provide anti-inflammatory activity complementary to the antioxidant benefits
Soy isoflavones (genistein, daidzein) have phytoestrogenic activity in vitro; at cosmetic topical concentrations, clinical estrogenic effects are not expected or documentedSoy allergy: individuals with soy food allergy should be aware, though topical protein exposure differs from dietary — patch test recommended for those with severe soy allergy

Glycine Soja (Soybean) Peptide

Glycine Soja (Soybean) Peptide is a hydrolyzed soy protein fraction consisting of small peptides (oligopeptides and amino acids) derived from soybean. The peptide fraction is separated from larger proteins and lipids, providing a concentrated mixture of skin-conditioning small molecules. In cosmetics it functions as a barrier-supportive humectant and skin conditioner, contributing bioactive peptides with potential collagen-stimulating and elasticity-improving activity.

Soy protein hydrolysate peptide fraction containing small bioactive peptides (2–10 amino acids) with documented skin-conditioning, moisture-retention, and barrier-supportive activitySoy-derived peptides include those with ACE-inhibitory and collagen-stimulating activity in vitro; the cosmetically relevant fraction improves skin elasticity and hydration in short-term use studiesProvides a reservoir of amino acids for natural moisturizing factor replenishment, supporting stratum corneum moisture balance
Soy-derived; individuals with severe soy food allergy should exercise caution with topical application, although the allergenicity of extensively hydrolyzed peptides is substantially lower than intact soy protein

Glycoproteins

A broad INCI category covering proteins covalently linked to carbohydrate chains. In cosmetics, 'Glycoproteins' as a listed ingredient typically refers to the glycoprotein fraction derived from yeast ferments (Saccharomyces cerevisiae) or bacterial ferments. Functions as a humectant and skin-conditioning agent. The term is less specific than named glycoproteins such as Fibronectin or Laminin — it indicates a mixed glycoprotein fraction rather than a single defined molecule.
