Sucralose is a high-intensity artificial sweetener occasionally used in topical and oral-care/cosmetic formulations as a taste-masking or flavoring agent. In skincare it serves a formulation role rather than as an active treatment ingredient.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation | Rare | Mild localized irritation possible in sensitive individuals at high concentrations. |
