@wuchangwen looks directly into camera and speaks calmly and professionally:
“真正不刺激的A醇，必须做好三点：第一，脂质包裹，先把A醇兜住；第二，分层释放，让活性一点点进皮肤；第三，修护同步启动，提前稳住屏障。少一个，都会翻车。” — while touching three matte-white physical models on the bench: lipid sphere, multi-layer capsule, ceramide block. Background shows pH meters and homogenizers (displays blurred).
