9:16 vertical TikTok UGC video, filmed in a real modern bathroom with soft vanity lighting and realistic handheld camera motion. A natural, relatable, real-life young woman (20s) holding GuruNanda whitening strips packaging, speaking directly to the camera with friendly energy. She showcases the product, opens the packet, pulls out one whitening strip, demonstrates application to her teeth, places it on, smiles, talks with it on, and shows close-ups of her teeth before and after. She moves casually, joyful, lightly dancing and gesturing like a happy influencer. Camera has natural micro-shakes, autofocus breathing, warm skin-tone lighting, realistic shadows, glossy porcelain details, clean bright mirror reflection, no AI distortions, no glitching hands or teeth. Product text sharp, packaging realistic, strip texture visible, teeth alignment natural. Realistic audio-visual feel like a trending TikTok product demo. High quality skin texture, smooth transitions, upbeat mood, confident expression, natural beauty, lifestyle realism. Final shot: she smiles showing brighter teeth and holds product near face while slightly dancing.
