TikTok Problem→Solution 15s (Skincare)

9:16 vertical, 15-second TikTok ad for a vitamin-C serum, shot as authentic UGC on an iPhone in a bright bathroom, natural morning window light, no studio polish. Beat 1 (0-2s) HOOK: creator (mid-20s, no-makeup, relatable) suddenly thrusts the phone close to her face, eyes wide, pointing at a dark spot, on-screen energy high — one surprised word mouthed. Beat 2 (2-5s) PROBLEM: she holds up two foundation bottles, rolls eyes, slumps slightly, shows the spot again in soft shadow. Beat 3 (5-10s) DEMO: quick jump cuts — dropper on fingertip, patting onto cheek in slow-mo macro showing the lightweight serum absorb instantly, skin texture real, not glass-fake. Beat 4 (10-13s) RESULT: whip cut to 10-second time-lapse split effect / same angle radiant skin in golden light, genuine small smile; she nods approvingly. Beat 5 (13-15s) CTA: holds bottle in frame center, finger taps empty space above (for caption arrow), bright clean background. Handheld, fast jump-cut rhythm matching a trending upbeat track, punchy sound effects on each cut, realistic bathroom details (towel, plant), zero plastic- skin smoothing, no on-screen text (added in edit), face consistent across cuts. ================================================================================
