Uncompromising Skincare Quality Control
LIZEE's quality control system is GMPC and ISO 22716 certified, covering raw materials, in-process control and finished products. With microbial, chemical and stability testing at every stage, we protect your brand from the #1 risk in cosmetics — contamination.
Comprehensive Full-Process Testing
We implement strict quality checks at three key stages: raw material inspection (IQC), in-process control (IPQC), and final product inspection (FQC) to guarantee excellence.
In-House QC Laboratory
Our well-equipped lab with HPLC, GC, and other advanced instruments allows for rapid and accurate testing, shortening production cycles and ensuring data integrity.
Certificate of Conformity for Every Batch
An advanced ERP and batch management system creates a unique identity for every product, enabling full traceability for complete transparency and safety.

One Product, One CodeTHE #1 SAFETY PRIORITY
Microbial Control: The Core of Product Safety
Contamination is the leading cause of cosmetic recalls globally. That is why microbial safety protocols are integrated into every production stage rather than treated merely as a final checkpoint.
Our microbiology laboratory conducts total aerobic microbial count and yeast & mold enumeration per ISO 17516, screens for specific pathogens (Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans, E. coli), and validates preservative efficacy under ISO 11930 standards.
Why it matters to your brand:Microbial contamination is the #1 reason cosmetics fail customs borders or get recalled. With LIZEE, every batch is verified against international microbial limits before it leaves the factory.

| 1. Chemical Raw Material Testing | 2. Packaging Material Testing |
|---|---|
| The first line of defense for product safety and efficacy. We have established a full-process monitoring system from supplier qualification to raw material acceptance before production. | Protecting content integrity and consumer experience.We believe the quality of packaging is as important as the product itself. |
| Safety & ComplianceEliminating all potential risks through heavy metal screening, microbial limit control, and irritation assessments. | Safety & CompatibilityEnsuring absolute safety inside and out with content compatibility and harmful substance migration testing. |
| Purity & PerformanceEnsuring every drop is effective via active ingredient analysis and key physicochemical measurements. | Physical & Mechanical PerformanceWithstanding all challenges from factory to use, verified by sealing, physical strength, and barrier performance tests. |
| StabilityGuaranteeing consistency throughout the product lifecycle with environmental simulations and accelerated aging tests. | Functionality & DurabilityOptimizing every nuance of use through component lifespan tests and user experience assessments. |
Full-Process Traceability System
We deliver not just a product, but peace of mind from absolute transparency. Scan the unique code to witness its complete journey from source to your hands.
2. Production Coding
Recording every detail into our ERP system — enabling two-way traceability from finished product back to raw material lots.
3. Quality Inspection & Release
Endorsing quality with data — every product is released with a verifiable "Certificate of Conformity" after passing all QC gates.

Skincare Quality Control – Frequently Asked Questions
Essential answers regarding our analytical testing, clean-room standards, microbial control, and international regulatory compliance.
Is LIZEE certified under international cosmetic quality standards?
Yes. LIZEE operates a 6,000 m² certified facilitystrictly compliant withISO 22716:2007 (Cosmetics GMP)andUS FDA GMPC guidelines, covering raw material quarantine, vacuum compounding, clean-room filling, and packaging.
Why are ISO 22716 and GMPC the most critical certifications for cosmetics manufacturing?
ISO 22716 and GMPC represent the global gold standards for cosmetic safety, hygiene, and batch consistency. ISO 22716:2007 ensures comprehensive quality compliance across compounding, clean-room filling, and storage (mandatory for EU and global markets), while US FDA GMPC enforces stringent microbial limits and sanitization required for North American compliance under MoCRA. Together, they guarantee your products are manufactured in a sterile, legally compliant environment.
Why is an SGS-audited certification recognized with higher authority globally?
SGS is the world’s leading inspection, verification, and testing body, trusted by international health authorities and global retail chains. SGS enforces rigorous on-site audits covering facility engineering, pure water conductivity, microbial limits, and equipment calibration. Holding SGS-audited GMPC and ISO 22716 certifications provides undisputed proof of factory capability, streamlining customs clearance and retailer onboarding for your brand.
What quality tests are standard for skincare products?
Standard testing protocols include microbiological limit assays (ISO 17516),preservative challenge tests (ISO 11930), accelerated stability cycles, in-house heavy metal screening (Pb, As, Hg, Cd), and active ingredient concentration assays via HPLC/GC.
Can you provide third-party test reports?
Yes. In addition to our in-house Certificate of Analysis (COA), we coordinate third-party verification and batch testing through accredited laboratories includingSGS, Intertek, and TÜV upon request.
How do you trace each production batch?
Every lot is assigned a unique batch code in our ERP system that establishes full two-way traceability linking finished units back to incoming raw material certificates, operator logs, compounding tank IDs, and final lab release records.
What is your product stability testing process?
We perform accelerated thermal aging (40°C / 75% RH for up to 3 months), freeze-thaw cycling (-15°C to 45°C), centrifugation, and light-exposure testing to ensure physical and chemical stability over a standard 3-year shelf life.
What happens if a batch fails quality inspection?
Any non-conforming batch is immediately placed under electronic quarantine. We trigger a documented CAPA (Corrective and Preventive Action) root-cause investigation, and no product is ever released until all corrective measures are verified.
Do you test packaging materials for safety and compatibility?
Yes. All primary containers undergo formula compatibility screening, vacuum leak tests, torque/drop tests, and pump lifespan trials (500+ actuations) to prevent leakage, material degradation, or clogging.
Can you support FDA registration and export compliance?
Yes. We assist with US FDA MoCRA facility listings and product filings, EU Regulation (EC) No 1223/2009 compliance dossiers (including CPSR requirements), and supply batch-specific MSDS/COA documents for customs clearance.
Do you keep batch samples for future reference?
Yes. Retention samples from every manufactured batch are archived in temperature-controlled retention rooms for 3 years (exceeding product shelf life) to support regulatory audits and post-market tracking.
