Succinoglycan is a high-molecular-weight bacterial exopolysaccharide produced by fermentation, used in skincare as a thickener, stabilizer, and moisturizing film-forming agent. It improves product texture and helps form a hydrating, protective layer on the skin's surface.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation or stinging | Rare | Polysaccharides of this type are generally well tolerated; mild irritation is uncommon. |
Contact allergy or sensitization | Very rare | Allergic reactions are seldom reported in the literature. |
Transient stickiness or tackiness | Uncommon | A cosmetic/sensory issue rather than a true adverse effect, dependent on formulation concentration. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
