UGC：精华试用的怀疑者

A woman in her late 20s films a selfie video in a sunlit bathroom, holding up a plain frosted serum bottle with no label, one eyebrow raised, then dabs a drop on her cheek. Handheld phone framing with a natural little shake, soft morning window light, an honest bare-face look. She says in a dry, conversational American accent: {My skincare routine used to have twelve steps. Now it's just this. I'm as suspicious as you are.} Raw UGC selfie style, natural light, no color grade. <a light bathroom echo, a small laugh>.
