2250

The retail channel is Farmacias San Pablo in Mexico, and the rollout is store by store. Each location gets its own printed shelf codes and its own geofenced campaign radius, so a scan can be attributed to the store where it happened. The experience is Spanish throughout, and nothing on the path from shelf to result asks for an app install or an account.

The customer-facing platform and the retail flow behind it:

• A 60-second AI skin scan reading multiple skin signals from a phone camera, built to work in shop lighting rather than ideal conditions.
• A recommendation engine resolving those signals into one of more than a thousand formula combinations from fifteen targeted pods.
• An in-store journey from a shelf QR code straight into the scan, with no app and no account required to reach a result.
• A fully Spanish experience, because the entire retail channel is Mexican and a scan that lands in the wrong language ends there.

The hardest measurement problem was not on the site. 2250 runs geofenced campaigns around San Pablo locations, and the question the marketing spend turns on is whether someone who saw an ad actually walked in and scanned.

That journey crosses from an ad impression to a physical store to a QR scan, with no login anywhere along it. We built the tracking to join those steps without asking a customer to identify themselves, so the campaign can be judged on store behaviour rather than on clicks.

Retail surfaces fail in ways a web product does not. A QR code printed on a shelf cannot be redeployed, so when codes at one location resolved to the English assessment instead of the Spanish one, the fix had to be on our side and immediate.

Photo capture got the same treatment: lighting in a pharmacy aisle is not lighting in a studio, and the scan is tuned for the room it is actually used in.
