Private Label Face Serum With Vitamin C Supplier & Factory

Oxidation is caused by oxygen exposure, free radicals, high pH, and UV light. In our facility, we solve this via a four-tier hurdle technology: First, we formulate with high-stability derivatives like 3-O-Ethyl Ascorbic Acid or adjust L-Ascorbic Acid formulas with Ferulic Acid and Vitamin E (tocopherol) to regenerate the ascorbic radical. Second, our mixing and storage tanks operate under an inert nitrogen blanket. Third, during bottling, we apply an inert gas flush to displace air in the bottle headspace. Finally, we recommend UV-blocking amber, cobalt, or fully opaque airless pump packaging.

OEM (Original Equipment Manufacturing): You provide the exact formula, formulation specifications, or proprietary active ingredients, and our factory handles compounding, microbiological testing, filling, and packaging strictly to your technical dossier.

ODM (Original Design Manufacturing): You provide your performance targets and marketing requirements; our R&D lab designs a bespoke formulation from scratch, develops packaging concepts, conducts 3-month stability trials, and delivers an exclusive shelf-ready product.

Private Label: You select from our library of over 3,500 mature, clinical-tested benchmark formulas (such as our high-potency 15% Vitamin C glow serum), apply your label, logo, and secondary packaging, allowing you to launch within weeks with reduced MOQ and minimal upfront R&D expense.

For catalog-standard private label formulations using our in-stock packaging inventory (such as standard amber glass droppers), MOQs generally start around 1,000 to 3,000 units. For fully customized chemical formulations (custom viscosity, bespoke derivative blending, unique fragrance profiles) or custom-molded/silk-screened bespoke containers, our baseline production run typically requires 5,000 to 10,000 units to ensure optimum production line efficiencies and cost competitiveness.

Our factory operates under ISO 22716:2007 (Cosmetics GMP) and US FDA CFSAN GMPC guidelines. For each manufactured batch, we supply the complete Certificate of Analysis (COA), 16-section Safety Data Sheets (MSDS), and Preservative Efficacy Testing (PET). For specific international markets, we prepare the Cosmetic Product Safety Report (CPSR) and assist with EU CPNP notifications, US FDA MoCRA facility registrations, Certificate of Free Sale (CFS), Certificate of Origin (CO), and SASO certification for the Middle East.

Every production batch undergoes strict in-process control (IPC). We utilize High-Performance Liquid Chromatography (HPLC) to confirm that the active concentration of ascorbic acid matches label claims precisely. We also conduct spectrophotometric color index monitoring to establish a baseline chroma, automated pH and viscosity verification, as well as 48-hour microbial testing prior to packaging release. Retained production samples from every single run are cataloged in our climate-controlled retention room for 3 years.
