片段 2｜三大高频陷阱：泵头 + 透氧 + 吸附
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:
“第一个坑：泵头兼容性——压不出、回弹慢，不是料稠，是泵和体系不匹配。第二个坑：铝箔袋透氧，VC、A醇打样时就在衰减。第三个坑：瓶身材质吸附活性成分，瓶子在偷料。” — while holding a disassembled pump mechanism (plastic parts only, no brand marks) in his left hand, and pointing to a row of sealed aluminum pouches inside an oxygen permeability tester (display blurred). Scene set in a material interaction lab with GC-MS in background.
