Characteristics | Common salicylic acid | Water-soluble salicylic acid-cyclodextrin inclusion complex | Demonstration of Advantages |
Solubility | Very poor; adjust with alcohol or an alkaline agent. | Excellent, readily soluble in water. | More flexible formulation, lighter and fresher skin feel. |
Irritating | Relatively high, especially for sensitive skin. | Significantly reduce | More gentle, suitable for a wider range of users. |
Stability | Prone to oxidation, discoloration, and degradation. | Significantly improve | Longer-lasting efficacy and appearance |
Bioavailability | Relatively low, constrained by solubility limitations. | Significantly improve | Better absorption, stronger efficacy. |
Mode of action | Instantly, quite strong | Sustained release, controllable | More long-lasting and gentle effects |
