A professional skincare brand from Taiwan partnered with us to develop a custom broad-spectrum sunscreen formulated for the local humid subtropical climate. The client prioritized product efficacy verification, safety compliance and full testing support, and was looking for a reliable OEM partner with standardized quality control systems.
Our R&D team developed a lightweight, non-greasy sunscreen formula adapted to high-temperature, high-humidity conditions, and shipped customized samples via international courier for the client’s hands-on evaluation. After receiving and testing the samples, the client confirmed full satisfaction with the texture and skin feel, and moved forward to inquire about complete testing arrangements. The client requested detailed information on available third-party testing items including SPF rating, UVA/UVB protection, PFA measurement, sensitive skin irritation test and sweat resistance test, and also asked for clarification on whether microbial examination, challenge test and stability test were performed in-house or by external third-party laboratories.
We provided a clear, itemized overview of all available testing services, test scopes and corresponding cost estimates, and explained our standard in-house quality control protocol, which includes microbial inspection for bacteria and fungi for every production batch. Once the client confirmed the testing plan met their brand compliance requirements, we finalized all product specifications, testing timeline and mass production arrangements.
The full production batch was completed on schedule and passed all required quality and efficacy tests. Impressed by our professional technical support, transparent testing process and consistent product quality, the client has continued our ongoing partnership and expanded the collaboration to include additional sun care and skincare SKUs.
