Format spotlight: FOOH, 3D and the smart mirror

Beauty brands keep producing eye-catching out-of-home moments — but several of the most-shared aren’t bought media at all. This spotlight sorts the formats getting attention right now: FOOH, 3D anamorphic, and the mirror screen that actually sits in the salon — what each is, and where it fits.

FOOH: the viral that never existed

The giant mascara wands sweeping a London bus, the handbags rolling through Paris on car wheels — beauty’s most-shared “OOH” moments were CGI composited onto real footage, simulating installations that never physically existed (Digiday, PAPER — primary). This is FOOH (fake out-of-home): a social/earned-media video, not a bought screen. It’s cheap, fast, and built for the “is it real?” share loop — a production and social line item, not a media buy. (Full breakdown: FOOH, 3D & anamorphic for beauty.)

3D anamorphic: the real premium format

By contrast, anamorphic 3D is genuine bought DOOH — forced-perspective content on a real corner LED that appears to leap out, with the naked eye (it’s monocular forced perspective, not stereoscopic). Beauty has run it for real: a major brand placed an anamorphic campaign across ~280 UK DOOH screens (invidis — primary). It’s a premium awareness format that also generates a shareable clip — so a brand can run anamorphic for real in-market presence and let the video travel.

The key distinction worth restating, because it trips everyone up: FOOH and 3D look identical in a clip and are completely different buys. One is CGI social content; the other is real bought inventory. Budget and plan them separately.

The smart mirror: beauty’s own format

While FOOH and anamorphic chase spectacle, the format that actually defines beauty DOOH is quieter: the mirror screen at the styling chair. It’s a commercial LCD behind two-way (“transflective”) glass — reads as a mirror when off, shows content through the glass when on. It does a different job from a viral stunt: not awareness spectacle but repeated, in-context, brand-safe attention at the point of grooming. The one hard fact that keeps recurring: the glass passes only ~30% of light, so a mirror needs a 700+ nit commercial panel to look good (the hardware reality). The smart mirror is the format the whole category is built on — and the one with the most room to grow as penetration rises.

Where each fits

A beauty brand can use all three for different jobs:

FOOH — cheap, viral, top-of-funnel social spectacle (with the ASA caveat: a fake result you can’t deliver isn’t excused by a “CGI” label).
3D anamorphic — premium in-market awareness that doubles as shareable content.
The mirror screen — the contextual, considered, point-of-service layer the others can’t reach.

The thread: spectacle formats (FOOH, anamorphic) buy attention at scale; the in-venue mirror buys attention in context. Both have a place — just don’t confuse the social clip for the salon screen.
