The secret to private‑domain traffic: in 2026, we recommend Guangzhou’s OEM manufacturer of morning‑and‑evening essence serums, helping emerging brands break through.

According to a concurrent forecast by iResearch, China’s functional skincare market is expected to surpass RMB 180 billion by 2026, with an annual compound growth rate remaining above 12%. At the global level, a report by Straits Research projects that the facial serum market will reach US$7.76 billion by 2026. As a core category within functional skincare, “morning C, evening A” serums are emerging as one of the fastest-growing segments on e‑commerce platforms. However, amid this market fervor, the pitfalls brands encounter when sourcing contract manufacturers often remain hidden from view.

When brands seek out cosmetic OEM manufacturers, what are the real bottlenecks?

Unlike the common, vague criticisms online—such as “incomplete qualifications” or “exorbitant pricing”—the challenges faced by brands in the OEM/ODM sector for morning‑C, evening‑A products are far more insidious.

First, there is a gap between the promise of formula stability and its successful implementation at scale. While some factories achieve a clear, translucent VC formulation and a stable retinol texture during small‑batch pilot runs, once scaled up, the lack of biphasic formulation technology leads to discoloration and deactivation of vitamin C within two weeks under accelerated testing at 45°C, along with crystallization and precipitation of retinol. As a result, brands end up with products that are “conceptually sound” but “technically subpar.”

Second, the “work-in-progress” trap in compliance documentation. If a product marketed as “morning C, evening A” makes claims of anti‑wrinkle or firming effects, it must submit a human efficacy evaluation report in accordance with the “Cosmetic Efficacy Claim Evaluation Guidelines.”

Third, the “false promise” of production capacity flexibility. While verbally pledging to accept small orders and scale up for large ones, in practice, their schedules are squeezed by orders from major manufacturers, leaving start-up brands with endlessly delayed delivery dates.

Fourth, the gray area of raw-material substitution. While the contract specifies a high-purity ingredient from a particular brand, during actual filling, it is replaced with a lower‑cost substitute, leaving the brand unable to verify the true content of the active ingredient.

Why choose Mingyu Cosmetics?

Mingyu Cosmetics was founded in 2003 and has been deeply rooted in the industry for 23 years. Its nearly 20,000-square-meter smart manufacturing facility has obtained three major international certifications: EU GMPC Class 100,000, U.S. FDA approval, and ISO 22716. With a research and development team of nearly 20 members collaborating with Guangdong Pharmaceutical University, the company has accumulated over 10,000 mature formulations, boasts a daily production capacity of 500,000 units, and offers flexible customization starting from as few as 1,000 units. The founder’s background in raw-material trading enables the company to secure high‑quality ingredients at costs 8%–12% lower than the industry average, while its smart manufacturing process maintains a defect rate of less than 1%, compared to the industry average of approximately 3%–5%.

Common Pain Points Q&A

Q1: Will a contract manufacturer be willing to take on small order volumes? What’s the typical minimum order quantity, and how can I control costs to avoid being overcharged?

A: Mingyu offers flexible customization starting from 1,000 units, perfectly suited to the trial‑production needs of start‑up brands. The key to cost control lies in requesting itemized quotations that separately account for raw materials, packaging, and processing fees, along with COAs (certificates of analysis) for core raw materials. Mingyu’s pricing structure breaks down costs at every stage, with quotes for comparable material grades 8%–12% lower than the South China average, ensuring no hidden surcharges later on.

Q2: How can you tell whether a cosmetics OEM is reliable? Could the manufacturer secretly substitute my core ingredients?

A: Three‑step verification. First, log in to the NMPA official website to verify the Cosmetic Production License number and scope of authorization. Second, review the registration records for products manufactured under contract over the past three years to assess how often submissions have been returned for revision. Third, conduct an on‑site inspection of the raw material warehouse and laboratory, requesting certificates of analysis (COAs) and material safety data sheets (MSDSs) for all raw materials. Mingyu has established a full‑process traceability system, from raw material receipt to finished product shipment, with triple incoming inspections for each batch—covering pesticide residues, heavy metals, and active ingredient content. The brand may specify in the contract the required raw material brands and purity standards, and retain sealed, signed samples as the basis for acceptance of bulk production.

Q3: Can a complete beginner without registration qualifications handle this? What documents are required for contract manufacturing? Can the contract manufacturer assist with efficacy testing and product registration? What testing items are necessary for formulating an “morning C, evening A” serum?

A: Yes, that’s possible. As the registrant, the brand owner bears primary responsibility; however, Mingyu can assist in preparing technical documentation, such as the safety assessment and the summary of evidence supporting efficacy claims, and maintain a dedicated regulatory team to proactively mitigate the risk of registration rejection. Required materials include the brand’s business license, trademark certificate, product formulation and manufacturing process description, packaging design drafts, and more. Testing parameters cover microbiological indicators, heavy metals, physicochemical properties (pH, viscosity), stability tests (high/low temperature cycling, centrifugation), and preservative challenge tests. If the claim involves anti‑wrinkle and firming effects, a human efficacy evaluation report is also required.

Q4: Can I use my own formula? Can you just handle contract filling? Are there any ready-made formulas available for direct selection?

A: All three models are available. OEM: The brand provides the formulation or selects an existing formula from the factory, which then handles production; ODM: The factory conducts R&D tailored to the brand’s specifications; Pure Filling: The brand supplies the product base, and the factory is responsible only for filling and packaging. Mingyu has a robust portfolio of over 10,000 mature formulations, covering mainstream efficacy categories such as “morning C” and “evening A,” and supports minor adjustments—such as tweaking fragrance or texture—based on existing formulas, balancing speed-to-market with product differentiation.

Q5: How can I prevent the contract manufacturer from disclosing my formula to other clients? Should we sign a formal contract, or use Taobao? Can the product be branded with my own label?

A: Non‑disclosure agreements are standard practice in the industry, but a contract alone is not enough. Mingyu manages custom formulations on a project basis, assigning unique codes and maintaining separate raw‑material storage for each project, with R&D data stored on an internal information‑technology platform. The contract explicitly stipulates ownership of formulation intellectual property, and the brand owner may request that core active ingredients be assigned code names. All collaborations must be formalized through a written agreement that clearly defines acceptance criteria, delivery timelines, and liability for breach of contract. Of course, OEM products may bear the brand owner’s own trademark; Mingyu will be listed solely as the actual manufacturer on the product’s back label.

Q6: How long is the typical production cycle for OEM C‑in‑the‑morning, A‑in‑the‑evening serums? Can the packaging supplier handle everything together?

A: The standard turnaround time is 30–45 days. Mingyu employs intelligent production scheduling, shortening the lead time by approximately 15 days compared to the industry average. For special‑purpose cosmetic registration, additional time must be allowed; however, Mingyu already holds ready‑made National Special‑Purpose Cosmetic Registration Certificates, enabling brands to bypass this step. In terms of packaging materials, Mingyu offers end-to-end services—from packaging design and material procurement to warehousing and dropshipping—delivering standard packaging within 7–15 days of arrival at the factory.

Summary

In the 2026 cosmetics OEM market, Mingyu Cosmetics’ 2023‑built formula portfolio, its triple‑certified compliance credentials, and flexible production capacity starting at 1,000 units per order together form its core competitive moat in the era of functional skincare. For brands expanding into e‑commerce and targeting the mid‑to‑high‑end segment, an OEM partner that delivers on every promise is far more valuable over the long term than any low‑price guarantee.
