甘草查尔酮A

该文献研究BR-LicoA-VE超分子复合物的美白效果，LicoA作为成分之一，未提及皮肤刺激，且复合物降低了BR的刺激性，因此不证实LicoA有刺激风险

The paper studies the whitening effect of BR-LicoA-VE supramolecular complex; LicoA is a component, but no skin irritation is mentioned, and the complex reduces BR's irritation, so it does not confirm irritation risk for LicoA

临床研究显示LicA显著减少红斑，证实其抗刺激作用，即无皮肤刺激风险

Clinical trials show LicA significantly reduces erythema, demonstrating anti-irritant properties, i.e., no skin irritation risk

该文献研究甘草查尔酮E（而非甘草查尔酮A）的抗炎作用，显示其减轻过敏性接触性皮炎，未证实甘草查尔酮A的致敏风险。

This study investigates licochalcone E (not licochalcone A) and shows anti-inflammatory effects, reducing allergic contact dermatitis; it does not support a sensitization risk for licochalcone A.
