What it is
Glycoproteins are biological macromolecules in which sugar units are covalently linked to a protein backbone, often sourced from yeast ferments or other biotechnological processes. In cosmetic formulas they function as humectants and conditioning agents, helping bind water at the skin surface and leaving skin feeling smooth and hydrated. They are typically included at low concentrations as part of moisturizing or soothing complexes.
Safety & warnings
Glycoproteins are generally well tolerated in cosmetic use. As with any protein-containing ingredient, sensitization is theoretically possible but uncommon at typical use levels. They are not considered comedogenic.
Origin & sourcing
Commonly produced through fermentation or biotechnological methods, or isolated from natural biological sources.
Questions everyone asks
What are glycoproteins in skincare?
They are protein molecules with attached sugar chains that act as humectants and conditioning agents, helping skin retain moisture and feel smooth.
Where do cosmetic glycoproteins come from?
They are often produced by fermentation or biotechnology, or isolated from natural sources, then refined for use in formulas.
