AI UGC Ad: Vitamin C Serum, "2-Week Dark Spot Check-In" (9:16)

Brief: A self-initiated portfolio project. Create a realistic UGC-style video ad for a Vitamin C brightening serum that makes a skincare claim feel believable.

What I made: A vertical 9:16 GRWM mirror check-in. I wrote the hook, the script and the AI video prompt, then generated the video from the product image so the bottle and label stay consistent.

Hook: “Okay, I need to show you what two weeks of this did.”

Why it works: The two-week time frame makes the result feel earned. Handheld selfie framing and natural window light keep it looking like a real routine, and the claims stay soft (“looks brighter”) so the ad stays realistic.

Tools:OpenArt, Seedance 2.0 Mini, AI video prompting, UGC scriptwriting.

Result: A finished 9:16 ad ready for Reels, TikTok and Shorts.
