Inside the factory
What a 3,886 m² skincare plant actually looks like
Most factory pages describe capability. This one shows the rooms the work happens in — material preparation, the Grade D cleanroom line, automatic crystal mask filling, the microbiology and formulation labs, and the bay where containers are loaded. Photographed on site; every number below is either a certificate number you can check or a field published on our Alibaba.com profile.
What can a buyer verify about this factory before placing an order?
Factory capability at Skincraftlab is verifiable rather than claimed. Manufacturing runs in a 3,886 m² GMPC cleanroom in Nanlang, Zhongshan, Guangdong, on 8 in-house production lines covering hydrogel casting, liquid filling, sealing and patch assembly — nothing is subcontracted, which is why bulk production runs approximately 20 days after confirmation. Environmental monitoring in the D-class workshop measured 126,079 particles per m³, which is 3.6% of the 3,520,000 limit for that grade. Manufacturing is certified to ISO 22716:2007 (CN19/31476) and US FDA CFSAN Cosmetic GMP (CN19/31477), both issued by SGS and valid to 2028-09-03 (SGS, 2025), alongside NMPA production licence 粤妆20160335 and FDA facility registration FEI 3015316073. In practice, buyers verify these by requesting the certificate PDFs and the batch documentation for a recent run.

What you can actually customize
Our Alibaba.com profile carries structured customization fields; here is what those mean in production terms. Everything below is either a field published on that profile or a format we already run in volume.
Colour
White, Pink, Gold, Purple, Yellow, Orange, Green, Black and Ivory are listed on our store profile, and colour is handled at the sheet, essence and packaging level rather than as a surface print.
Materials and formats
Non-woven, PVC and cotton are the base materials on our profile; in production we also run hydrogel, crystal hydrogel and bio-cellulose sheet formats plus reusable silicone patches.
Packaging
Single-sheet foil pouches, individual sachets and box sets of 5–20 pieces, with paper-bag outer packaging listed on our profile. Artwork, insert cards and pack counts are part of the project.
Customized on demand
Our profile flags customized-on-demand production: formula, essence volume, sheet die-cut and packaging are set per project instead of being locked to one catalog SKU.
Sample processing
Sample processing is listed as a service on our profile — development samples first, then a branded sample, then bulk.
How we work with buyers
Our store profile also lists offline trade-show participation and e-commerce capability as featured services — relevant if your channel is Amazon, retail distribution or DTC.
Production
Material preparation, the cleanroom filling line and the automatic filling station used for crystal hydrogel masks — the format behind our best-selling sheet mask listings.





Quality control and R&D
Microbiological testing and formulation development are in-house, which is why a formula question gets answered in days rather than weeks.




Warehouse and loading
Finished goods are palletised and released from the finished-goods warehouse, then loaded for Zhongshan Port or Guangzhou Port — the nearest ports listed on our store profile.



Watch the floor: production, outbound and laboratory
Filmed by our own team rather than stock footage: filling lines and the automatic bagging machine, outbound packing and container loading, and day-to-day laboratory work. The full set — including the crystal mask automatic filling line — is in our video centre, filterable by production, shipping and laboratory.
Verifying a factory before you commit
How can we verify the factory before placing an order?▾
Four ways, none of which rely on our word: check the certificate numbers on our certifications page against the issuing bodies (SGS CN19/31476 and CN19/31477), read the amfori BSCI audit (Monitoring ID 25-0314051-1), verify our FDA facility registration under FEI 3015316073 in FDA's Cosmetics Direct portal, and audit our Alibaba.com storefront where trading history and buyer reviews are published. We also welcome third-party inspections — the BSCI audit and our cleanroom test reports were produced exactly that way.
What cleanroom class do you run, and who verified it?▾
Our sixth-floor workshop is classified Grade D under GB 50591-2010 and the cosmetics production licence rules. The measured suspended-particle count was 126,079 per m³ against a limit of 3,520,000, tested on 24 April 2022 by Waltek (report WTZ22F04064875M). Bacterial count and illuminance were tested in the same series.
How many people actually work on quality and development?▾
Production runs with 48 line operators; quality is handled by 5 QA/QC inspectors plus the microbiology laboratory shown above, and development by an in-house team of 12 formulation scientists. Our Alibaba.com capability profile also lists 6 pieces of test equipment, material inspection records and supplier assessment.
Are the photographs on this page recent?▾
They are site photographs, not stock images. The cleanroom line images were taken in February 2026 and the crystal mask filling images in December 2024. We update them as equipment changes rather than reusing older shots indefinitely.
