Why "which supplier is best" is the wrong first question

I've been on the buying side of moisturizer for six years. The question I get most from founders, distributors, and e-commerce sellers is some version of: who's the best supplier? I've stopped answering that directly, because it's the wrong question. The right one is narrower and much more useful: which of three sourcing paths am I actually on?

Get that wrong and even a competent factory will produce a bad outcome — not because they failed, but because you asked them to do a job that wasn't theirs.

The three paths, short version:

  • You don't have a formula. You need a base you can customize, or a catalog formula with your branding on it.
  • You have a formula. You need equipment, batch records, and a quality system — a toll manufacturer.
  • You have neither, and you have no time. You buy finished goods and resell them.

Most of the SKU list doesn't change the answer. A supplier that can build a rich cream for dry skin can usually build the lighter gel a men's line wants, and most requests for a "natural face moisturizer" turn out to be an ingredient-list problem, not a factory problem. The one thing that does override the whole framework is three letters: SPF. More on that below, because it's where most first-time buyers lose money.

Scenario 1: You need a formula, not just a factory

This is the launch scenario. You have a positioning, a target consumer, a packaging idea, and no R&D team. What you're really buying is someone else's development work, lightly edited.

What to ask, roughly in this order:

  • Which formula in your catalog is closest to what I described, and what's the MOQ on that base versus a customized version of it?
  • Is the fill weight net or gross? What's your fill tolerance?
  • Do you already hold a stability file on that base, and does it cover my packaging — or only your stock jar?
  • If I pay for customization, who owns the resulting formula? Get this in writing, not in a call.

Here's the part that surprised me. Everything I'd read about sourcing said negotiate hard on unit price. In practice, for a first order, the lever that mattered was MOQ, not price. I once paid roughly 18% more per unit on a 2,500-unit run than the price I'd been quoted at 10,000 units — and it was the right call. We sold through in five months. The "cheaper" option would have left me with 7,500 units of a cream we were about to reformulate anyway.

Ballpark ranges from quotes and public quote-request forms I collected during 2025 and into 2026, for a 50ml cream in a stock jar, filled and labeled:

  • Around 1,000–3,000 units: roughly $1.60–$3.50 per unit
  • Around 10,000 units: roughly $0.90–$1.80 per unit

Treat those as ordering-of-magnitude, nothing more. They move with the actives, the preservative system, the jar, and how much of the fill is hand labor. Verify against current quotes; I re-check ours every quarter and they've never stayed still.

One more thing about claims. "Natural" is not a legally defined term in the US or the EU — it's a marketing word backed by whatever certification you buy (COSMOS, Ecocert, Natrue) and whatever you can defend. That's usually the most expensive sentence in the brief, because natural-preservative systems are fussier, challenge testing gets longer, and fragrance-free plus natural is a genuinely hard combination to stabilize. If your differentiation is "natural face moisturizer," budget for testing before you budget for packaging.

Scenario 2: You have the formula and need someone to run it

Toll manufacturing looks simpler than it is. You're not buying a product; you're buying a process executed to your specification, and the gap between those two things is where batches fail.

The questions that matter here are unglamorous:

  • What's your smallest commercial batch, and can you run a pilot at a tenth of it first?
  • What yield loss do you allow for, and who eats it?
  • Who performs micro testing and challenge testing, and is the lab accredited to the standard my retailer accepts?
  • If an ingredient is backordered, what happens? I want "no substitution without written approval," in the contract.

That last one is not hypothetical. I assumed "same specification" meant the same product across two manufacturers. It didn't. The emulsifier system had been swapped for a functionally equivalent alternative, which is a completely reasonable thing for a plant to do — and the finished cream felt noticeably different on the skin. Same spec sheet. Different product. Now every purchase order we issue carries a substitution clause, and it costs me nothing to include.

Scenario 3: You're reselling finished goods

The least glamorous path is often the correct one. If you're testing whether a moisturizer belongs in your catalog at all, buying 500 units of an existing product beats spending four months and five figures on development.

The whole game here is exclusivity. Ask directly: can I be the only seller of this exact SKU in this exact packaging on this channel, and what does that cost? The answer is frequently "no," or "yes, for a fee and a volume commitment." Both are fine answers. What isn't fine is discovering eighteen months later that four other stores are selling an identical tube.

Also confirm who owns the artwork and whether the product is already notified in your market. In the EU that means a Product Information File and a CPNP entry; if the factory can't show you one, the product isn't ready to sell there, no matter how good the sample feels.

The scenario that breaks the pattern: anything with SPF

This is the counterintuitive part, and it's where the framework above stops applying.

In the US, a moisturizer with SPF is regulated as an over-the-counter drug. That means a Drug Facts panel, a facility registered for drug manufacturing, in vivo SPF testing, water-resistance testing if you claim it, and batch records on file. In the EU and UK it stays a cosmetic, but you still have to substantiate the SPF and the UVA protection with recognized test methods, and hold the file to prove it.

The consequence nobody warns you about: SPF testing is quoted per formula, per protection level, and a meaningful change to the formula can mean testing again. In the quotes I've seen through 2025–2026, that line item lands in the low four figures per formula, before stability and compatibility work. So a "simple SPF add-on" routinely costs more than the rest of the development budget combined.

Which flips the recommendation. For a face moisturizer with SPF under about 5,000 units, the cheaper path is almost always to buy a base that has already been tested and is sold as a stock formula — not to commission one. The expensive-looking option is the cheap one. The custom route only pays off once you're committing to volume and a claim you intend to defend for years.

The line items that never make it into the quote

I've learned to ask "what's not included" before "what's the price." The unit price is the least informative number in the document. What sits outside it, in rough order of how often it surprises people:

  • Development or formulation fee — sometimes refundable against a later order, sometimes not
  • Stability, compatibility, and challenge testing
  • SPF and UVA testing, always a separate line
  • Filling and assembly, charged per unit and sometimes per component
  • Decoration setup: screen, plate, or mold fees, per SKU, per component
  • Regulatory dossier work and market notification
  • Cartons, labels, shrink, shippers
  • Freight, duties, and which tariff code the goods clear under
  • Rework if the first batch misses spec
I've learned to ask "what's not included" before "what's the price." The supplier who lists every fee upfront — even when the total looks higher — has come in cheaper on landed cost three times out of four. Not always. Three out of four.

The reverse is the pattern I've stopped falling for: a quote that's 20% under everyone else, followed by a revision fee, a testing surcharge, and a decoration setup that appeared from nowhere. A good face moisturizer is not hard to make. A quote that survives contact with the invoice is harder.

One expensive lesson, briefly. We once booked stability and micro testing through a lab that was cheaper by about $600. The report came back and our retail partner rejected it — the lab wasn't accredited to the standard they required. We paid for the testing twice and lost three weeks. Saved $600, spent roughly $1,900 and a launch date. Now accreditation is the first question I ask, before price.

How to tell which scenario you're in

Answer these in order and stop at the first one that applies.

  1. Do you have a written formula — ingredient percentages, process steps, and test methods? If yes, you're in Scenario 2 and the conversation is about capability, not creativity.
  2. Does your claim list include SPF, or anything that sounds medical? If yes, go straight to the SPF section and assume stock base until volume proves otherwise.
  3. Can you realistically sell 3,000–5,000 units in twelve months? If no, Scenario 3 — or Scenario 1 on a stock base with your label on it.
  4. Is your packaging already chosen and sourced elsewhere? Filling customer-supplied components is fine, but it adds handling fees and shifts some liability to you. Ask about it explicitly.
  5. If the first batch fails, can you absorb the cost without ending the year? If not, take the smallest MOQ on offer and pay the higher unit price. Cash exposure beats unit economics at this stage. Every time.

Pick the scenario before you send the brief. The same three-paragraph request sent to the same three factories produces three wildly different quotes if you haven't decided whether you're buying a formula, a batch, or a box — and you'll end up comparing numbers that were never measuring the same thing.

Face moisturizer sourcing isn't hard because the product is complicated. It's hard because most buyers don't know which of the three purchases they're making until the invoice arrives.
