Hyaluronic Acid Serum Manufacturing

For a stocked formula in a standard component, 1,000 pcs per SKU. A custom formula or a custom component starts at 3,000 pcs — the component supplier carries its own MOQ and the line has to be stripped and validated between runs, so short runs cost us more than they cost you. If you are testing a market, say so: we would rather book a first run into a shared filling slot than lose the project. Tell us the volume you are working with and we will confirm the lowest workable MOQ.

Two routes. A sample set of existing formulas goes out at cost, and the fee is deducted from your first bulk order. Or we develop to your brief: you approve a lab sample, then a pre-production sample made on the actual filling line, and only then do we book the run. You see what the line produces before you pay for the run. Ready to evaluate? Request a sample set and we will send the current set with the spec sheets.

Your approved sample becomes the reference standard. We keep sealed retains from that batch, the production batch is checked against it for color, odor, viscosity and pH, and every batch ships with a COA listing the results. If bulk deviates from the approved sample on any of those parameters, we remake it or credit it — that is written into the contract, not just said on a call. Ask for the sample-to-bulk comparison sheet and we will attach it to your quote.

The base formula is ours and stays shared. Everything you build on top of it — active combination and percentage, texture, fragrance, color — is yours: 24 months of exclusivity in the markets we agree in writing, and we will not sell that combination to anyone else in those markets. You can extend the term, buy the formula outright, or take the full documentation to another factory if you ever move production. Need exclusivity in a specific country? Tell us the market and we will put the term in the contract.

Yes — and we would rather see your market list before quoting than discover a missing document after production. Standard set: COA, MSDS, stability and compatibility data, microbiological and heavy-metal testing, plus the ingredient data your safety assessor needs. Market-specific: EU CPNP notification support, UK UKCPR, US MoCRA facility registration and product listing, and ASEAN notification for the specific country you sell in. Selling into more than one market? Send us the list and we will map the documents to each one before you commit.

25–35 days after sample approval for a stocked formula in a standard component; add 10–15 days if the component is custom or needs a new mould. You get a written milestone schedule — formulation, component arrival, filling, testing, release — with a photo update each week. If we miss a milestone for reasons on our side, we cover the difference to air-freight the balance so your launch date still holds. Have a fixed launch date? Share it with us and we will build the schedule backwards from it.

Every quote is itemised: formula and filling, component, secondary packaging, testing, documentation. Only two things move after quoting — component price (we re-quote only if resin or glass moves more than 5%) and artwork changes made after plates are cut. Mould and plate fees are one-off and stated up front; nothing is added at the end. Want the line-by-line breakdown before you commit? Request an itemised quote.

30% deposit to book the production slot, 70% against the bill of lading copy. T/T by default; L/C at sight or a platform-held payment for a first order if that suits your procurement rules better. Returning customers move to 30-day terms after three clean shipments.

Send us the batch number, photos, and — if you can — a third-party test within 30 days of arrival. Where the fault is ours we replace the goods or credit you, and we will tell you plainly what our own checks missed. We will not ask you to dispose of stock before we have seen the evidence.

Both are formulation choices, not properties of hyaluronic acid. Pilling comes from high-molecular-weight HA sitting on the surface with the wrong film former; we balance the weights and adjust the polymer system so it layers cleanly under sunscreen and foundation. We run a layering test with your intended companion products if you tell us what else is in the routine.

A single-weight HA only ever does one job. We combine several — high weight for surface film and immediate smoothness, mid weight for the upper layers, and low or oligo weight for deeper hydration — because the blend is what makes the product feel like something rather than like water. Want a specific sensorial profile? Describe the finish you want and we will engineer the blend to it.
