We conduct 5000-cycle scratch tests (500g load, 2.5H hardness), ensuring ≥98% gloss retention (ΔE≤0.4, imperceptible color shift) for your custom gel polish, delivering military-grade resistance to infant nail scratches. This test fully simulates high-frequency wear scenarios such as handwashing, housework, and typing. It not only resists various daily frictions but also ensures the gel polish stays intact on nails for up to 3 weeks without peeling or lifting, maintaining a vibrant color and smooth finish. We also evaluate post-test aging to comprehensively guarantee the durability of your custom gel polish, building a long-lasting reputation for your brand.
