Humectant
Glyceryl Polyacrylate

A synthetic polymer formed by esterification of polyacrylic acid with glycerol. Functions as a water-retaining humectant and film-former, creating a gel-like texture on skin that binds moisture. Distinct from carbomer-family thickeners in that glyceryl polyacrylate contributes directly to skin hydration rather than just viscosity. Widely used in lightweight gel moisturizers and essence-type formulas.

Hydrophilic polymer forms a lightweight hydrogel film on skin that binds water and reduces transepidermal water lossProduces a soft, silky skin feel without tackiness — popular in lightweight gel and essence formulasDerived from glyceryl ester modification of polyacrylic acid; compatible with a wide range of pH and active ingredients

Glycine

The simplest amino acid, used as a humectant that supports the skin's natural moisturizing factor.

Humectant
Glycogen
GLYCOGEN

A polysaccharide (branched glucose polymer) used in cosmetics as a humectant and skin-conditioning agent. Distinct from mussel-derived glycogen; in skincare typically sourced from yeast or oyster glycogen.

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.

Hydrolyzed Avocado Protein

Enzymatically or chemically hydrolyzed protein from avocado (Persea gratissima), yielding small peptides and amino acids. These fragments have affinity for skin and hair surfaces, forming a moisture-retaining film and providing a soft, smooth feel. Used in moisturizers, serums, and hair treatments.
