Trehalose
Trehalose; mild humectant and stabilizer for proteins/actives; hygroscopic, light skin feel.
Pentylene Glycol
Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin
Propanediol
Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative

Tranexamic acid for skin brightening; generally mild at low external doses.
Allantoin
Skin soother at 0.5-2%; promotes cell regeneration
Disodium EDTA
Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
Caprylhydroxamic Acid
Chelating agent to stabilize metal ions; often paired with antioxidants for system stability, used at low levels
