Glycoproteins are protein-carbohydrate complexes used in skincare for their moisturizing, film-forming, and skin-conditioning properties, often derived from plant, microbial, or marine sources. They help retain hydration and support the skin barrier rather than acting as a strong therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
Mild irritation or redness | Uncommon | Possible in sensitive individuals, typically transient. |
Allergic contact dermatitis | Rare | Protein-derived components can occasionally trigger sensitization. |
Immediate hypersensitivity / urticaria | Very rare | Reported mainly with proteins from common allergen sources (e.g., certain marine or plant origins). |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
