Full-Process Quality Inspection Loop | Every Bottle of Gel Polish Undergoes 30+ Rigorous Tests

We have established a full-process quality inspection loop from raw materials to finished products, where every bottle of custom gel polish undergoes 30+ rigorous tests: raw materials are tested for purity and harmful substances via spectrometers, particle dispersion (≤5μm) is monitored under microscopes after mixing, bubble residual rate (＜0.01%) is controlled by laser detectors during degassing, ±0.01g precision verification is conducted after filling, and finished products undergo adhesion tests (ensuring 3-week durability), weather resistance tests, and compliance certifications such as EU EN71-3 and US FDA. Our QC team records batch testing data in real time via 0.1mm precision microscopes and data systems, supporting QR-code traceability. This ensures stable quality for large-scale production and precise quality control for small-batch customization, making every bottle of your custom gel polish safe, long-lasting, and compliant.
