Eye-Area EMS Beauty Device: From Multi-Sample Benchmarking to Urgent Weekend Cargo Receipt
A Japanese client approached GAMU seeking to develop a custom eye-contour EMS beauty device on a tight schedule: an initial trial run of 50 units within a 2-month delivery window. To navigate China OEM development under tight timelines, we immediately began by auditing internal circuit configurations and procuring diverse prototype samples for hands-on evaluation.
Relying on product photos and catalog specifications alone made it difficult to finalize the technical plan: developing a new mold would require lengthy design iterations, and devices with similar exteriors often differ significantly in internal structure and output feel. We arranged multiple physical sample configurations and shipped them in stages so the client could evaluate actual performance alongside the technical documentation.
Having physical prototypes in hand transformed technical discussions into precise decisions: electrode head curvature, current intensity curves, and skin adhesion were refined based on sensory user trials and hard engineering tolerances.
During the critical final phase, the partner factory dispatched an expedited production batch that arrived at our Guangzhou facility late on a Saturday night. GAMU personnel stood by on-site over the weekend to immediately unload, perform initial receiving inspections, and safely store the goods in a secure warehouse storage area. (The photographs below capture that Saturday night receiving operation.)
