Choosing a pore refining serum manufacturer requires more than comparing ingredient lists and unit prices. A commercially reliable supplier must translate a product brief into a stable formula, substantiate its claims, control batch variation, and deliver the documentation required by the destination market.
China offers a substantial manufacturing base for this work, particularly in Guangzhou and the wider Guangdong cosmetics cluster. According to Guangzhou Customs figures published by the municipal government, Guangzhou exported RMB 11.63 billion in beauty, cosmetics, and washing-care products in 2025, an increase of 25.2%. These figures cover a broader category than facial serums; they should not be presented as pore refining serum export statistics. [gz.gov]
This guide compares ten China-based manufacturing operations that buyers can investigate for private label and custom serum projects. The evaluation prioritizes factory credentials, formulation capabilities, quality-control transparency, production suitability, and export support—not promotional claims alone.
For professional procurement teams, traceability is the most useful starting point: the ability to connect a supplier's claims to a legal entity, production site, formula version, test report, and released batch.
The following screening framework separates an attractive sales presentation from a factory worth qualifying.
| Evaluation area | Evidence buyers should request | Why it matters |
|---|---|---|
| Factory identity | Business registration, manufacturing address, production license where applicable | Confirms who actually manufactures the product |
| Manufacturing controls | Current ISO 22716 or relevant GMP documentation with site and scope | Helps establish whether the assigned facility follows appropriate cosmetic manufacturing practices |
| Serum development | Development brief, formula version history, ingredient specifications, pilot samples | Shows whether customization extends beyond adding fragrance or changing labels |
| Quality assurance | Incoming-material checks, batch records, release specifications, deviation procedures | Makes consistency assessable |
| Product validation | Stability, microbiological quality, packaging compatibility, claim-support documentation | Connects the formula to its intended shelf life and marketing |
| Commercial execution | Written MOQ, packaging commitments, milestone schedule, change-control terms | Reduces surprises after sampling |
| Export readiness | Destination-specific documentation and clearly assigned regulatory responsibilities | Prevents factory credentials from being mistaken for product authorization |
ISO 22716 addresses cosmetic good manufacturing practices. ISO 17516 addresses microbiological quality. Neither, by itself, proves that a serum reduces the appearance of pores or that a particular finished product is ready for every export market. [iso]
Public manufacturing figures below are supplier-reported or attributed to the cited source. They are not audited here, and total skincare capacity is not equivalent to available pore refining serum capacity.
The value of a cosmetics cluster lies in the connections between formulators, ingredient distributors, testing providers, packaging manufacturers, and filling operations.
Guangzhou's 2025 Cosmetics Industry White Paper describes a differentiated industrial structure across Baiyun, Huangpu, Huadu, and Conghua. The report highlights coordinated development rather than a single, uniform manufacturing base. For buyers, this makes Guangzhou a useful location for evaluating formula development and packaging execution together. [gz.gov]
The practical advantage is not simply lower production cost. It is access to multiple stages of product development within an established supply-chain ecosystem.
Guangzhou's 2025 export figures demonstrate substantial international trade activity. They do not establish that every local factory understands a buyer's destination-market requirements or that every serum has appropriate substantiation. [gz.gov]
A sensible sourcing strategy therefore combines cluster access with factory-level qualification and finished-product testing.
"Not confirmed" means that a sufficiently specific figure or current certificate was not established from the sources reviewed. It does not mean the supplier lacks the capability.
| Manufacturer or operation | Procurement focus | Published capacity indicator | MOQ position | Certification or compliance evidence to verify |
|---|---|---|---|---|
| LAIMEI | Flexible OEM/ODM development for emerging and growing brands | Company brief states over 50 million units annually across categories | Website advertises orders as low as 500 units; project conditions require confirmation | ISO 22716 and GMPC stated in company brief; obtain current certificates |
| TY Cosmetic | Broad skincare and haircare programs | Three factories reported in company materials | Obtain SKU-specific quotation | GMP manufacturing claims; verify assigned-site documentation |
| Ausmetics | Export-oriented skincare and personal care | No directly comparable annual serum figure confirmed | Obtain formula-and-packaging-specific MOQ | Website states ISO 22716, ISO 9001, and GMPC |
| Xiran | Private label skincare and broader cosmetic ranges | Public profiles describe a facility exceeding 20,000㎡ | Obtain written MOQ for the selected production route | ISO 22716 and GMPC publicly reported; verify current copies |
| Guangdong Bawei | Structured ODM/OBM development and broader portfolios | Website states 400 million units annually across categories | Project-specific | Company states ISO 9001, ISO 22716, GMPC, and ISO 14001 |
| Nox Bellcow | High-volume skincare and mask programs | Website states over 1 million skincare bottles daily | Project-specific | Company lists ISO 22716 and other management-system credentials |
| COSMAX China | Research-led ODM and larger development programs | Substantial China manufacturing network; no uniform serum-specific figure used here | Project-specific | Request certificates for the factory actually assigned |
| Intercos China | Development-intensive and premium-positioned projects | China serum-specific capacity not confirmed | Project-specific | Request China-site and product-scope evidence |
| Kolmar Beijing | China-market development supported by group R&D | Current comparable serum capacity not confirmed | Project-specific | Verify Beijing-site credentials separately |
| Kolmar Wuxi | Industrial-scale ODM within Kolmar's China network | Factory completed in 2018; current serum allocation requires confirmation | Project-specific | Verify Wuxi-site credentials separately |
Sources: LAIMEI's website and the company information supplied for this article; TY's company page; Ausmetics' website; public Xiran profiles; Bawei's website; Nox Bellcow's website; and COSMAX, Intercos, and Kolmar materials. Capacity periods, product mixes, and counting methods differ, so these figures should not be used as a directly comparable production ranking. [lmoemcosmetics]
LAIMEI is a relevant first candidate for brands seeking coordinated formula development, packaging support, and manufacturing without immediately committing to enterprise-scale purchasing.
- Establishment: the supplied company brief states 13 years of experience; an exact legal incorporation year was not independently established.
- Location: Guangzhou, Guangdong.
- Market coverage: the supplied brief states exports to more than 100 countries and regions; named principal markets require confirmation.
- OEM/ODM scope: formula development, packaging design, manufacturing, and associated project support.
- Procurement fit: emerging and mid-sized brands that place value on accessible order sizes and direct development communication.
The supplied brief describes a 20,000㎡ GMP-standard production base and annual capacity exceeding 50 million units across skincare categories. LAIMEI's public About Us page separately advertises trial orders starting as low as 500 units, alongside formula adjustment, packaging optimization, and logistics-related support. These are useful starting points for a quotation, not guarantees that every custom serum can be produced at that minimum. [lmoemcosmetics]
For a pore refining serum project, LAIMEI's potential value is the combination of flexible entry volumes and broad customization support. Buyers should test communication efficiency through a structured brief: ask the development team to explain ingredient choices, packaging limitations, required tests, and the consequences of each requested formula change.
Due diligence should also reconcile the company brief with the current website. The brief refers to more than 1,000 professionals across associated teams, while the website describes a broader team exceeding 2,000. Buyers should distinguish direct employees, partner-factory staff, and external specialists rather than combining these into a single in-house R&D headcount. [lmoemcosmetics]
The brief also mentions "MADS certification." Its issuing body, standard, scope, and validity were not established. It should not be treated as a recognized regulatory credential until supporting documentation is reviewed.
TY Cosmetic suits buyers considering a serum launch alongside future expansion into haircare, body care, or other skincare categories.
- Established: 2009.
- Location: Guangzhou, Guangdong.
- Market coverage: a 2025 company-issued announcement reported customers in more than 74 countries.
- OEM/ODM scope: skincare and haircare development, private label manufacturing, and end-to-end project support.
- Procurement fit: brands seeking a broad product platform rather than a single-SKU supplier. [video.tyoemcosmetic]
TY's company materials describe growth from one factory to three factories with an R&D laboratory. Its 2025 announcement reported a 70-member R&D team and more than 7,900 tested formulations. These are company-reported indicators, not evidence that a particular pore refining serum has completed claim testing. [video.tyoemcosmetic]
The most useful qualification question is whether the proposed serum comes from an existing validated platform or requires new development. That distinction affects sampling, test costs, packaging decisions, and launch timing.
Ausmetics is worth investigating for export-oriented brands that need broader formulation and documentation coordination.
- Established: 1998.
- Location: Guangzhou, Guangdong.
- Markets: its website identifies customers across more than 30 countries, including North America, Europe, Oceania, Southeast Asia, and other regions.
- OEM/ODM scope: skincare, body care, haircare, and sun care.
- Procurement fit: internationally positioned brands with detailed formulation and documentation requirements. [ausmetics]
The company publicly states ISO 22716, ISO 9001, and GMPC credentials, alongside FDA facility registration. Buyers should keep those categories separate: FDA registration is not FDA product approval or a quality certificate. [ausmetics]
For a pore refining serum, ask Ausmetics to connect its proposed formulation to the intended claim, target consumer, and final packaging system. General formulation expertise should be translated into a project-specific validation plan.
Xiran presents itself as a broad OEM/ODM manufacturer supporting private label cosmetics and skincare.
- Established: public supplier profiles identify 2013; verify the contracting entity's business registration.
- Location: Guangzhou, Guangdong.
- Markets: export-oriented profiles identify the United States, Europe, the United Kingdom, the Middle East, and Southeast Asia.
- OEM/ODM scope: formula development, sampling, packaging sourcing, filling, manufacturing, and export-oriented project support.
- Procurement fit: brands planning a wider skincare collection around an initial facial serum. [xiranskincare]
Public profiles describe a manufacturing facility exceeding 20,000㎡ and report ISO 22716 and GMPC credentials. These should be checked against the exact factory address and legal entity proposed in the contract. [xiranskincare]
Because "Xiran" appears across multiple web properties, buyers should confirm the relationship between the sales website, certificate holder, manufacturer, exporter, and bank beneficiary before making payment.
Bawei is a useful candidate for buyers seeking a structured development organization with testing support and multi-category capabilities.
- Established: 2006.
- Location: Guangzhou, Guangdong.
- Market coverage: the company describes service to more than 500 brands annually; a reliable geographic revenue breakdown was not established.
- Service scope: planning, R&D, testing, manufacturing, and ODM/OBM solutions.
- Procurement fit: buyers developing several products or requiring a more formal technical evaluation process. [baweicosmetic]
Bawei reports an independent third-party testing institution, more than 6,000 market-launched formulations, and ISO 9001, GMPC, ISO 22716, and ISO 14001 credentials. Its homepage states production capacity of 400 million units annually across its portfolio. [baweicosmetic]
For procurement, the key question is how those resources apply to the selected serum: which tests are included, who performs them, and whether the reports cover the final formula and packaging.
Nox Bellcow is particularly relevant for larger-volume skincare programs and buyers considering complementary mask products.
- Established: 2004.
- Location: Zhongshan, Guangdong.
- Markets: international distribution is reported, although the reviewed sources do not establish a current principal-market ranking.
- ODM scope: skincare, facial masks, and wipes.
- Procurement fit: higher-volume buyers with established specifications and replenishment forecasts. [hknbc]
Its website reports production exceeding one million skincare bottles daily and lists ISO 22716 among its certifications. That figure represents broad skincare output, not a dedicated pore refining serum line or immediately available capacity. [hknbc]
Buyers should request realistic minimum batch sizes for their formula, available filling formats, and the production slot that can actually be reserved.
COSMAX China merits consideration for buyers prioritizing research-led ODM and a substantial manufacturing organization.
- China entry: 2004.
- Operations: the group identifies manufacturing capabilities in China within its international network.
- Markets: Chinese beauty brands and the group's broader international customer ecosystem.
- ODM scope: skincare and cosmetics development and manufacturing.
- Procurement fit: brands with defined development requirements and sufficient purchasing scale. [cosmax]
COSMAX's scale is relevant, but global or national capacity should not replace a site-specific proposal. Different plants and development teams may serve different product categories.
For pore refining serum procurement, establish which China facility will develop, manufacture, test, and release the product. Ask whether the commercial forecast is suitable for that facility's batch economics.
Intercos is a candidate for development-intensive projects, particularly where formulation, sensory properties, and brand positioning must be coordinated closely.
- Group founded: 1972; this is not the establishment date of its Chinese legal entities.
- China presence: Suzhou manufacturing operations are evidenced in trade records.
- Markets: international beauty customers and regional brand programs.
- Service scope: cosmetic development, production, and packaging; the group also operates in skincare.
- Procurement fit: premium-positioned brands with a detailed development brief. [intercos]
Intercos' group capabilities should not be interpreted as proof that every China operation handles every skincare format.
Before requesting samples, confirm that the proposed facility accepts facial serum projects, supports the intended formula type, and can provide the required development and validation services.
Kolmar Beijing offers a China-based development route supported by Kolmar Korea's broader R&D organization.
- Established: 2007.
- Location: Huairou, Beijing.
- Markets: China is explicitly identified; wider international access forms part of the group's stated strategy.
- ODM scope: product planning, R&D, manufacturing, and quality control.
- Procurement fit: buyers seeking formulations adapted to Chinese market requirements within an established ODM network. [kolmar.co]
Kolmar's published material describes close cooperation between Beijing and Korea in development and quality management. Buyers should nevertheless obtain the actual project team, testing plan, and manufacturing-site details. [hkkolmar]
The Beijing and Wuxi operations belong to the same group. Comparing them is a site-allocation decision, not a comparison between independent suppliers.
Kolmar Wuxi provides another manufacturing option within Kolmar's China network.
- Factory completion: 2018; verify the legal entity's incorporation date separately.
- Location: Wuxi, Jiangsu.
- Markets: China-focused development within Kolmar's international production network.
- ODM scope: cosmetic product development and manufacturing, subject to project acceptance.
- Procurement fit: larger or more technically demanding programs where factory assignment is important. [kolmar.co]
The Wuxi site was described as a substantial ODM manufacturing plant when completed. Buyers should request current information rather than extrapolating today's output or available capacity from historical investment announcements. [koreabiomed]
For a pore refining serum, ask which existing formulation platforms are available, what customization changes trigger retesting, and whether the forecast fits the site's production planning.
"Pore refining" is a commercial description, not a single standardized formula.
A useful development brief distinguishes among:
- Reducing the visible appearance of pores.
- Improving the appearance of uneven skin texture.
- Supporting a less oily-looking finish.
- Providing hydration without an undesirable heavy afterfeel.
Require the supplier to explain what evidence supports the intended finished-product wording. Ingredient literature alone should not automatically be presented as proof that the completed serum delivers a quantified result. European cosmetic-claims guidance emphasizes truthfulness, honesty, and adequate evidential support. [webgate.ec.europa]
Avoid promising permanent pore closure or allowing a cosmetic brief to drift into unreviewed therapeutic claims.
A quotation listing "niacinamide serum" or "botanical pore serum" leaves substantial room for variation.
For each performance-critical ingredient, request:
- INCI identity and supplier.
- Raw-material specification and certificate of analysis.
- Whether the quoted percentage means raw-material input or active content.
- Relevant impurity and microbiological specifications.
- Storage conditions and retest or expiry information.
- Written approval requirements for substitutions.
Niacinamide is recognized in cosmetic ingredient safety literature as a skin-conditioning ingredient, but its presence does not independently prove a finished product's pore-related performance. [pubmed.ncbi.nlm.nih]
The proposed verification package should address:
1. Formula stability under justified storage conditions.
2. Microbiological quality.
3. Preservation suitability for the formulation.
4. Compatibility with the intended bottle, pump, dropper, and closure.
5. Release specifications for appearance, odor, pH, viscosity, and filling.
6. Evidence proportionate to the finished product's claims.
ISO 17516 provides a framework for assessing cosmetic microbiological quality. It is not a substitute for all other aspects of product safety, stability, or claim validation. [iso]
CE and RoHS should not be used as generic quality badges for an ordinary facial serum.
European Commission cosmetic-claims guidance explicitly states that a CE mark should not be applied to cosmetic products because it would suggest an incorrect regulatory regime. For EU sales, focus instead on the applicable cosmetics framework, safety assessment, Responsible Person arrangements, supporting documentation, and CPNP notification. [webgate.ec.europa]
Likewise, ISO 14001 concerns an organization's environmental management system. It should not be presented as proof that an individual serum is organic, biodegradable, or environmentally superior.
Match the supplier's legal entity and address across:
- Commercial quotation.
- Manufacturing agreement.
- Certificate holder.
- Factory audit.
- Product documentation.
- Payment instructions.
If the exporter and manufacturer differ, document their relationship rather than assuming they are the same company.
For claimed certifications, review scope, dates, certificate number, issuing body, and the manufacturing site covered. Do not accept a group-level credential as automatic evidence for every associated factory.
Ask for distinct minimums for:
1. Bulk formula production.
2. Filling and assembly.
3. Packaging procurement.
A low filling MOQ does not necessarily remove a higher minimum for a custom bottle or printed component.
Request written clarification on who owns unused packaging, where it will be stored, and what happens if the formula or artwork changes.
A practical sequence is:
1. Approve the written development brief.
2. Evaluate coded laboratory samples.
3. Select a formula version.
4. Test the selected formula in the intended packaging.
5. Complete the agreed validation work.
6. Approve a pilot or production-representative batch.
7. Retain signed reference samples.
Each approval should identify the formula version and packaging specification. A positive reaction to a laboratory sample should not become unrestricted permission to alter materials before commercial production.
Separate the timeline into formulation, sampling, testing, packaging production, pilot work, manufacturing, release, and freight.
A supplier may be able to fill an existing formula quickly while a fully custom development requires additional work. Obtain milestone dates and identify which changes can reset the schedule.
Confirm:
- Incoterm and importer responsibilities.
- Commercial invoice and packing-list requirements.
- Destination-specific labeling and documentation.
- Transport classification where relevant.
- Leakage protection and carton specifications.
- Inspection acceptance criteria.
- Responsibility for damage, customs holds, or missing documents.
For EU distribution, clarify who handles CPNP notification. For US distribution, assign responsibility for applicable MoCRA facility-registration and product-listing obligations rather than assuming a factory registration completes every requirement. [fda]
A procurement risk that deserves more attention is "equivalent" material substitution after sample approval.
Two materials can share an INCI name without being identical commercial grades. A botanical blend may also contain a carrier and only a limited proportion of the highlighted extract. Reviewing the ingredient list alone may therefore fail to identify a commercially meaningful change.
The protective approach is contractual:
- Identify approved suppliers or material codes for critical ingredients.
- Define acceptable alternatives in advance.
- Require written approval before substitution.
- Identify when a change requires stability, compatibility, safety, or claim reassessment.
- Link production batch records to the approved formula version.
- Retain samples from both the approved pilot and commercial batches.
Apply the same discipline to packaging. "Equivalent pump" should not mean an unreviewed change to dose delivery, closure performance, or product-contact materials.
These controls make incoming-material and batch traceability commercially useful, rather than merely administrative.
The right pore refining serum manufacturer depends on the project: launch volume, customization depth, target market, packaging complexity, and the evidence needed to support the product.
LAIMEI is a relevant starting point for buyers seeking flexible order entry and coordinated OEM/ODM support. Larger organizations such as Bawei, Nox Bellcow, COSMAX, Intercos, and Kolmar warrant investigation when purchasing scale or development complexity calls for a different operating model. Their suitability must still be demonstrated at the assigned-factory and finished-product levels. [lmoemcosmetics]
For a productive discussion with GUANGZHOU LAIMEI CREATIVE RESEARCH INTELLIGENT BIOLOGICAL RESEARCH CO.,LTD., submit a brief covering the target country, intended claims, benchmark texture, ingredient preferences, packaging format, launch quantity, and budget. Request a proposal that separates formulation, testing, packaging, manufacturing, and documentation responsibilities.
Obtain the complete certificate, not a cropped logo or screenshot.
Check the certificate holder, factory address, standard, scope, issue date, expiry date, and certificate number. Verify the status directly with the issuing certification body, including whether the certificate remains active rather than suspended or withdrawn.
Then confirm that the production site in your agreement matches the certified site. ISO 22716 relates to cosmetic manufacturing practices; it does not certify the pore-reducing effectiveness of a serum. [iso]
No. FDA states that cosmetic facility registration and product listing are not approval programs. FDA also states that it does not issue certificates confirming cosmetic facility registration or product listing. [fda]
For applicable US projects, confirm who handles facility registration, product listing, and the other relevant responsibilities. Covered facilities generally renew registration every two years, while responsible persons update product listings annually. Certain exemptions apply. [fda]
Do not assume so.
Have the formula, ingredient restrictions, intended claims, labeling, and documentation reviewed for each destination. EU market access involves its cosmetics framework and CPNP arrangements; applicable US obligations include MoCRA requirements. Completing one system does not automatically satisfy the other. [single-market-economy.ec.europa]
Build this review into development before ordering printed packaging.
Ownership depends on the agreement, not on the words "OEM," "ODM," or "custom."
Specify ownership of the base formula, ownership of modifications, permitted use by other customers, confidentiality, access to technical documentation, and any exclusivity by territory, channel, or term.
If future transfer to another manufacturer matters, negotiate the necessary rights and documentation before paying development fees.
Request the underlying finished-product study, not only an ingredient supplier's brochure.
Review the tested formula version, participant characteristics, duration, measurement method, statistical treatment, and the exact wording supported by the result. Establish whether the evidence remains relevant after formula or packaging changes.
European guidance requires cosmetic claims to have adequate evidential support and to avoid misleading presentation. A numerical claim should therefore be no broader than the study can justify. [webgate.ec.europa]
