Private Label Bio-Collagen Day & Night Facial Sheet Mask – OEM/ODM Manufacturer

Direct answer: GUOCUI Bio-Collagen Day & Night Facial Sheet Mask is a private-label sheet-mask concept for skincare brands, K-beauty and beauty-retail buyers, importers and e-commerce sellers that want one hydrating, pore-refining and firming mask SKU in a single-use 34 g sachet. The reference folder is 白变透面膜（黄色）26.5.14, and the featured image is a real PNG photograph from the local GUOCUI product archive, not an AI-generated image. The ingredient names and care lines printed on that sample sachet – collagen, oligo-hyaluronic acid, galactomyces ferment filtrate, plus the lines “hydrating, pore perfecting, firming” and “suitable for sensitive skin” – are the supplier’s own reference artwork. No concentration, molecular-weight figure, test result or certificate accompanied the folder, so none is stated as a fact on this page.

Product positioning

This concept is positioned as a single-use day-and-night facial sheet mask, supplied in a 34 g (1.19 oz) sealed sachet. It suits a brand that wants one mask SKU to anchor a routine rather than another leave-on serum, and it suits buyers whose assortments are already built around hydration and skin-texture stories.

The sample sachet in the reference photograph carries a gold kraft-look pouch with the headline “BIO-COLLAGEN COMPLEX – for luminous, smooth skin”, a “DAY & NIGHT MASK” band, the product line “BIO COLLAGEN FACE MASK – FACIAL SHEET MASK”, a “your logo” placeholder, and a stated net weight of 1.19 oz (34 g). Three care directions are listed alongside named ingredients: pore refining and skin firming with low-molecular collagen; deep hydration and plumping with oligo-hyaluronic acid; natural radiance and even skin texture with galactomyces ferment filtrate.

Mask formats behave differently from leave-on skincare in an assortment. They are low unit value, light to ship, easy to bundle and naturally repeat-purchase, which makes them useful for trial-driven merchandising, gifting sets and travel sizes. Treat the copy above as the artwork’s own description, not as a performance promise: the wording a brand finally prints is a market-by-market decision.

Suitable buyers

• Independent and K-beauty-inspired brand owners launching a first sheet-mask SKU.
• Pharmacy, drugstore and beauty-chain private-label programmes that need a routine add-on.

Custom formula directions

Directions that can be explored with the GUOCUI team; every one is confirmed only after a sample is produced and approved.

• Serum fill weight and viscosity band, agreed against the sachet size and the substrate chosen.
• Substrate format discussed with the buyer – spunlace non-woven, cupro-style and other sheet materials – with the final choice subject to a fit-and-drape sample trial.
• Humectant and hydration systems built around the buyer’s positioning.
• Galactomyces ferment filtrate as a named ingredient direction. No percentage appears on the reference artwork and none is published here.
• A low-molecular-weight collagen descriptor may only be printed when the buyer’s own documentation supports the figure; the artwork’s figure is treated as unverified reference text.
• Fragrance-free or essential-oil-free directions for sensitive-positioned ranges.
• Preservative systems and permitted ingredient lists matched to the destination market’s cosmetic rules.
• Colour, tint and pouch compatibility reviewed together, because a tinted serum can change how the print reads.

Boundary note: the folder supplied no concentration, no stability or microbiology report, no challenge-test result and no certificate. GUOCUI does not publish those as facts, and a brand should not print them until its own testing and documentation exist.

Packaging options

• 34 g single sachet, three-side-seal pouch with a tear notch.
• Film finish options: matte or gloss, kraft-look paper-feel laminate or solid colour.
• Front-panel “your logo” area with a full ingredient panel on the reverse.
• Batch code, best-before date and barcode placement agreed with the buyer.
• Multi-language labelling for cross-border retail.
• Outer cartons of 5, 7, 10 or 30 sachets, discussed per project as a merchandising direction rather than a fixed catalogue item.
• Sachet size, shape or substrate changes are possible but must be validated for fill weight and seal integrity before mass production.

Sample and QC workflow

1. Brief: the buyer supplies the destination market, target positioning, sachet count, serum direction, substrate preference, label languages and artwork status.
2. Base selection: GUOCUI proposes a serum base and substrate combination for the brief.
3. Sample production: trial sachets are produced so the buyer can assess texture, drape, scent and pouch feel.
4. Buyer review: the buyer confirms or requests changes to the serum, substrate, size and print.
5. Pre-production sample: a final sample is signed off and retained as the production reference.
6. Production checks: fill weight, seal integrity and print accuracy are checked against that retained sample.
7. Testing: stability and microbiological testing are organised with the buyer for the destination market; GUOCUI does not supply or imply a test result that has not been issued.
8. Documents and shipping: commercial invoice, packing list and the certificates the buyer’s market requires are prepared for the agreed shipment.

MOQ and quotation

Minimum order quantity, unit price, lead time and any tooling are confirmed in a written quotation for the specific project. They are not published on this page, because they change with fill weight, substrate, pouch material, print colours, carton configuration and destination.

To prepare an accurate quotation, GUOCUI needs: destination market; sachet count per unit and per carton; serum direction; substrate preference; sachet size; label languages; artwork status; whether a sample is required first; and the target launch date. Send those through the contact page and the team will respond with a written specification and price rather than an estimate.

Buyer FAQ

Is a sheet mask a cosmetic or a medicinal product?

A facial sheet mask is treated as a cosmetic in most markets when it is presented for cleaning, perfuming, changing the appearance, protecting or keeping the skin in good condition. The classification, the permitted claims and the labelling duties differ from market to market, and a product presented for a medical purpose is regulated differently. Confirm the classification for your destination before the label is finalised.

Are the ingredient levels or the collagen molecular weight on the photo verified?

No. The reference sachet names collagen, oligo-hyaluronic acid and galactomyces ferment filtrate, and it describes the collagen as low-molecular, but no analysis, specification sheet or test report was supplied with the folder. Treat those lines as supplier reference artwork. Any figure you print should be supported by documentation you hold.

Can the “suitable for sensitive skin” line be printed?

Not on the strength of the artwork alone. A sensitive-skin claim is normally supported by the formula’s ingredient list, a fragrance and allergen review, and in many markets by patch-test or compatibility evidence. GUOCUI can produce the product and supply the formula information, but the claim itself is the brand’s responsibility and should follow the destination market’s rules.

Can we change the sachet size, shape or substrate?

Yes, these are project decisions. Changing the sachet size affects the fill weight, and changing the substrate affects how the serum is retained, so any change is validated with a sample for fill weight and seal integrity before production.

What quality checks are recommended for a sheet mask?

At minimum: fill weight verification against the retained sample, seal integrity and leak checks on the finished pouch, print and label accuracy, batch coding, and stability and microbiological testing appropriate to the destination market. The exact scope is agreed per project and per market.

What information is needed to start an OEM/ODM project?

Destination market, product positioning, sachet count, serum direction, substrate preference, sachet size, label languages, artwork status, sample requirement and target launch date. With those, GUOCUI can propose a base, quote the project and schedule a sample.

Related sheet-mask and substrate directions

Buyers planning a mask SKU often need to settle the serum fill, the substrate, the pouch and the label handoff before they can price the project. GUOCUI has documented that handoff step by step in Sheet Mask Set Private Label RFQ: Serum Fill, Substrate, Pouch, and Label Handoff, which is a useful companion to this product page.
