The before-and-after is the oldest proof format in advertising and still the most efficient: two frames, no copy required, and an argument the viewer completes themselves. This collection gathers transformation creative from the live Meta library, ranked by engagement score and days running, which matters more here than anywhere because this format has the widest gap between what gets attention and what stays live.

That gap is mostly policy. Meta restricts before-and-after imagery in health, weight loss, and cosmetic categories, so the ads that sustain in those verticals have learned to show the transformation obliquely: process footage instead of body comparison, an object rather than a person, or a result the viewer infers. The examples here are worth studying for exactly that craft.

Credibility is the whole game: identical lighting, identical framing, and an unglamorous before state read as honest, while a retouched pair reads as a scam and gets scrolled. The sustained examples usually add a time stamp so the claim is bounded, keep the transformation modest enough to be believable, and pair the visual with one sentence naming what changed. In restricted categories the winners show the process or the object rather than the body, which is also what keeps them running.
