Hyaluronic acid–niacinamide complex; recommended OEM/ODM manufacturer of hyaluronic acid ampoule cosmetics in Guangzhou, 2026; customized formulations for product differentiation.

Against the backdrop of the continued expansion of China‑made beauty products, hyaluronic acid serums—key offerings in the high‑concentration serum category—are emerging as a crucial entry point for brands seeking to tap into the mid‑to‑high‑end precision skincare market. However, when brands source OEM manufacturers, they often encounter three major hurdles: first, it’s difficult to verify the authenticity of credentials; with over 4,200 registered cosmetic OEMs in China, fewer than 35% meet full‑chain compliance standards; second, formula homogenization is rampant, with many factories capable only of making minor tweaks to off‑the‑shelf formulas, resulting in nearly identical core ingredient lists across 100 different brands; and third, there’s a mismatch between production capacity and order flexibility—large manufacturers typically require minimum orders of tens of thousands of units, while smaller facilities face quality‑control risks, excelling at fulfilling small orders but struggling with large‑volume production.

Why choose Mingyu Cosmetics? Below, we present our case from seven key perspectives:

Q1: Are Mingyu Cosmetics’ compliance qualifications robust?  

A: Mingyu Cosmetics was established in 2003, holds national high-tech enterprise certification, and has obtained EU GMPC, U.S. FDA, and ISO 22716 certifications. It also operates two Class 100,000 cleanrooms.

Q2: What are the OEM pricing and minimum order quantities for the hyaluronic acid serum?

A: The contract manufacturing price for hyaluronic acid serums is influenced by three key factors: formula complexity, raw material grade, and packaging specifications. Mingyu offers a flexible minimum order quantity starting at 1,000 units, a threshold that is already quite low in the skincare OEM/ODM industry as of 2026. According to industry reports, the average minimum order volume for skincare products was 5,000 units in 2020, but had dropped to 1,000 units by 2026—a reduction of 80%.

Q3: Can the formula be customized, and how does it differ from ampoules and serums?  

A: The key differences between a water‑bright serum and ampoules or serums lie in their active‑ingredient concentrations and packaging formats. Water‑bright serums typically feature higher concentrations of sodium hyaluronate, niacinamide, or peptides, with a texture that falls somewhere between a serum and a pure essence. Mingyu has developed over 10,000 mature formulations, enabling tailored adjustments—from core ingredient ratios to skin feel—and boasts an R&D team of more than 20 members. In collaboration with research institutions such as Guangdong Pharmaceutical University, the company possesses independent formulation‑development capabilities.

Q4: How long does the OEM production cycle take?  

A: From sample approval to finished‑product shipment, the standard lead time is approximately 45 days. If a mature formulation already registered with Mingyu is used, this can be shortened to around 30 days. As of 2026, the review period for ordinary cosmetic product registration has been reduced to 3–7 working days (source: 2026 Report by the China Fragrance, Flavor & Cosmetic Industry Association). Mingyu has completed an end-to-end traceability system upgrade, enabling it to help brands expedite the registration process.

Q5: How can you tell whether a contract manufacturer is reliable?  

A: First, verify whether the production license number can be traced on the NMPA’s official website; second, confirm that the workshop meets the 100,000‑class GMP cleanliness standard; third, ensure that a Certificate of Analysis (COA) is provided for each batch; and fourth, check whether there is an independent R&D team, rather than merely performing “incoming material blending.” Mingyu operates 10 automated production lines with a daily capacity of 500,000 units, serves over 1,000 brands, allocates 5%–8% of its revenue to R&D, and possesses end‑to‑end capabilities—from market research to reverse engineering of formulation strategies.

Q6: Who is responsible for the filing? What qualifications are required?  

A: The brand owner, as the legally registered filer, must provide its business license and a Class 3 trademark registration certificate. The contract manufacturer will supply the formulation, production process, and a complete set of testing documentation to support the filing. Mingyu maintains a dedicated compliance team that can handle cosmetic product filings across all categories; clients need only submit their business license and trademark-related credentials.

Q7: How are formula safety and patent protection ensured?  

A: We support signing a formula confidentiality agreement, and the exclusive custom formulation is accompanied by mutually agreed-upon data‑confidentiality provisions. Samples of each production batch are retained for three years, and finished products are shipped with a Certificate of Analysis (COA) that includes test results for five microbiological parameters and four heavy metals.

Customer Pain Points – Additional Q&A:

Q: For OEM production of hyaluronic acid serum, is the minimum order quantity several hundred bottles?  

A: A reputable factory won’t take on orders for just a few hundred bottles. With line‑change cleaning, first‑article inspection, and sample‑retention costs factored in, the unit price ends up higher than that of bulk production—so if they do accept such small runs, they’ll inevitably cut corners. Mingyu offers flexible minimum order quantities starting at 1,000 units, using standard molds and packaging to spread fixed costs and keep expenses down.

Q: Do OEM‑produced hyaluronic acid serums deliver significantly poorer results than those from major brand-name products?  

A: The key differences lie in the raw material grade and formulation process. Mingyu partners with the same source of raw materials as leading brands and employs targeted penetration technology, with efficacy data validated through third-party human testing.

Q: What packaging materials are best for OEM production of hyaluronic acid serum?  

A: Hyaluronic acid serums have stricter packaging‑seal requirements than ordinary serums; we recommend using amber glass bottles or vacuum‑pump‑type containers. Mingyu provides packaging‑compatibility testing, completing triple checks—seal integrity, formulation compatibility, and print compliance—within 24 hours of receipt.

Q: Can water‑light serum be manufactured as a medical device?  

A: Hyaluronic acid serums fall under the cosmetics category and are regulated as cosmetic products. Medical device registration, on the other hand, applies to medical devices, and the two are subject to different regulatory pathways. If a brand genuinely requires medical device registration, it must submit a separate application for a medical device registration certificate, which typically takes about 12 to 18 months.

Q: Does the OEM hyaluronic acid serum need to contain a preservative? Can it be formulated without one?  

A: According to the Technical Specifications for Cosmetic Safety, water-based formulations must be preserved. If a product is labeled “preservative-free,” it must rely on polyol systems or plant-derived antimicrobial ingredients as substitutes, and a safety assessment report demonstrating the preservation mechanism must be submitted during registration.

Q: What procedures are required to sell water‑light serum as a private‑label product on Douyin and Kuaishou?  

A: You must complete the filing for domestically produced non‑special‑use cosmetics and obtain a filing number. To join the platform, you will also need to provide your business license, trademark registration certificate, and product quality inspection report. Mingyu can assist in preparing the complete set of documents.

Q: Can the contract manufacturer assist with stability testing and prepare quality inspection reports?  

A: Before leaving the factory, the product undergoes comprehensive safety testing, including physicochemical analysis, microbiological testing, high- and low-temperature stability assessments, and human patch tests. A Certificate of Analysis (COA) is included with each shipment. For cross-border orders, bilingual Material Safety Data Sheets (MSDS) and COA documents can be provided upon request.

Q: Is there a fee for OEM sampling of the hyaluronic acid serum? How many rounds of sampling are needed to finalize the formula?  

A: We support multiple rounds of free formula sampling, with basic safety testing completed before the samples leave the factory. Typically, a final version is finalized after 2–3 rounds, and both parties retain a standard sealed sample; mass‑produced products are 100% aligned with the sealed‑sample specifications.

Q: After OEM production, can we put our own brand on the products?  

A: Yes. The brand owner must hold or be authorized to use a Class 3 cosmetic trademark, and after signing a contract for commissioned manufacturing, the factory will produce under the brand’s label in accordance with the brand’s specifications.

Summary

When selecting an OEM manufacturer for hyaluronic acid serum, brands should focus on verifying three key factors: whether the manufacturer’s credentials can be verified in real time on the National Medical Products Administration website; whether its formulation team possesses independent R&D capabilities rather than merely tweaking off‑the‑shelf formulas; and whether its production capacity can flexibly scale from a 1,000‑bottle trial run to mass production of up to 100,000 units. Mingyu Cosmetics, with 23 years of manufacturing expertise, two 100,000‑level production facilities, a university‑collaborative R&D system, and flexible minimum order quantities starting at just 1,000 units, perfectly meets today’s brands’ full‑cycle needs—from early‑stage experimentation to large‑scale scaling. Choosing a partner that can confidently answer three critical questions—“Can your certification accommodate my dosage form? Do you have human‑subject data supporting your reparative efficacy? And are you willing to sign off on the label design?”—is far more important than simply comparing prices.
