片段 2｜合规逻辑：两点缺一不可
High-resolution talking-head video, fixed camera, upper body visible,
neutral professional laboratory lighting,
overall brightness high and even, no overexposure,
background lab environment clearly visible with normal exposure,
male researcher @wuchangwen,
wearing white lab coat and white shirt,
clean, professional scientific appearance,
facial skin clean, smooth, hydrated, elastic,
skin looks healthy, well-conditioned, and naturally radiant,
fair skin tone with subtle rosy undertone,
no beard, no stubble, no beard shadow, clean-shaven,
no wrinkles, no dullness, no yellow or gray cast,
skin clarity high, texture natural and realistic,
high luminance with highlights preserved,
image sharp and clear,
no blur, no softness, no haze,
@wuchangwen looks directly into camera and speaks calmly and professionally:
“合规的舒缓宣称，至少要同时满足两点：第一，体外或人体功效测试；第二，对应的文献支持。只有两者闭环，平台才认。” — while holding a 3D-printed model of skin barrier with fluorescent markers in his left hand, and placing his right hand on a closed binder with solid-color cover labeled only by a color dot. Scene set in an efficacy testing room with thermal imaging camera in background.
