The Lens that reached 185 million people
When I set out to build "Bald Version," I wasn't chasing a viral moment — I was chasing believability. A face transform only spreads when people can't tell where reality ends and AR begins.
1. Believability beats novelty
The single biggest lever for reach is realism. A bald transform that breaks on different face shapes, skin tones or lighting will never be shared. I built a custom face-occlusion segmentation and a procedural scalp shader that adapts skin tone in real time.
2. Design for the share, not the open
Reach is a function of shares, not opens. Every decision — the framing, the reveal, the first half-second — was tuned to make people want to send it to a friend.
3. Performance is a feature
A Lens that drops frames feels broken. Keeping the experience at a smooth frame rate on mid-range phones was as important as the visual itself.
The result: 185.02M reach and the top Lens in my catalogue. The lesson — polish and performance are what turn a clever idea into a global one.
