Proteins bound to sugars (often yeast-derived). They retain moisture and support skin comfort. Well tolerated.

BLimited evidence. One RCT or several controlled studies with limitations.
Hydrating protein components. Safe.
Glycoproteins (INCI Glycoproteins) are proteins with attached sugar chains, often obtained from yeast through fermentation. In a formula they act as a humectant: the sugar part holds water and the protein part leaves a sense of comfort, which is why they appear in serums and in moisturizing and soothing creams. On efficacy, they are a supporting component in hydration and soothing. There is some supplier backing for skin conditioning, but independent evidence is modest, so it is realistic to expect a humectant effect rather than a clear clinical result. Applied topically they have no systemic relevance, so they can be used during pregnancy and breastfeeding. Tolerance is good, with low irritation and allergy potential, suitable for sensitive skin. Since these are proteins, people already sensitized to yeast proteins may see an occasional reaction, though most do not.

The Evigrade extension adds an evidence panel to iHerb, Sephora, Druni and 12 more stores. This ingredient and every other one in the product show evidence-tier, allergen risk and pregnancy/lactation flags at a glance.
Glycoproteins is considered safe during pregnancy at typical cosmetic concentrations. Systemic absorption through the skin is minimal.
Glycoproteins suits: normal, dry, combination, oily, sensitive.
