Prototype notes

A first look at skin age, rendered like a Sephora cover.

Instead of dumping a dashboard of skin metrics on you, the device translates a near-infrared scan into a single number you can read across a room — and quietly nudges what to do next.

The purpose

A near-infrared device pairs with the app to read your skin and translate it into one number people can feel: skin age vs. biological age. Inspired by Whoop's recovery and Oura's readiness — a daily vanity metric that also flags what's off.

One hero number

Skincare is crowded with metrics. We collapse hydration, barrier, elasticity, evenness, and UV exposure into a single editorial numeral — then expose the underlying signals only when you want them.

Anomalies, not averages

Day-to-day shifts matter more than the absolute number. The app surfaces what changed (extra sun, dehydration) and ties it to a single recommended product — the loop that lets this live on a Sephora shelf.

Why this aesthetic

Warm neutrals, editorial serif, generous whitespace. Closer to Aesop and Alo than to a fitness tracker. The device and its app should feel at home on the vanity, next to the serum — not buried in a health dashboard.

Try the demo

1. Tap Hold to scan on the phone.
2. Watch the near-infrared read sweep across the aperture.
3. Read your skin age, delta, and today's flagged signal.
4. Tap the reset icon (top-right of the phone) to run it again.
