Anyone who has read enough ingredient lists eventually notices something uncomfortable. Products from very different brands, at very different prices, with very different stories, are frequently built the same way. The same emulsifier systems. The same thickeners. The same actives at plausible levels. The same order, roughly, in the top half of the list. This is not a coincidence and it is not fraud. It is what happens when many companies solve the same problem with the same materials under the same rules.
Stock bases and the ladder above them
Contract manufacturers maintain libraries of proven bases: a light lotion, a rich cream, a gel serum, a cleansing milk. These exist because they work, because their stability is already known, and because they can be made on the existing plant without a new process. A brand can buy in at several rungs of a ladder.
| Level | What the brand changes | Typical consequence |
|---|---|---|
| Private label | The pack and the artwork only | The product exists under several names at once, legitimately and with nobody deceived |
| Stock base with a tweak | Fragrance, colour, one added active | The product is genuinely different in one respect and identical in every other |
| Semi bespoke | Active system, sensory profile, sometimes the emulsifier | A distinctive product built on a known and de risked skeleton |
| Fully bespoke | The entire formula, developed from scratch to a brief | Slower and more expensive, and still frequently drawing on the same materials |
Each rung is legitimate. None of them is disclosed on the pack, and there is no requirement that any of them should be. A shopper cannot tell a private label product from a fully bespoke one by looking at it, which is precisely why the origin story does so much work in marketing.
The starting formulations that circulate
Raw material suppliers compete on ingredients, and the way you sell an ingredient to a formulator is to show it working. Suppliers therefore publish starting formulations: complete, competent, freely available recipes that place their material in a plausible finished product. These are technical marketing documents, and they are excellent.
They are also everywhere. When a new material becomes fashionable, dozens of brands approach it through the same handful of published starting points, adapt for cost and feel, and arrive in the same place. The convergence is not lazy. It is the rational response to a supplier having already solved the hard part.
A small pool of suppliers
Behind the entire sector sits a comparatively small group of speciality chemical companies producing emulsifiers, polymers, actives, preservatives and fragrance. A brand at any price point is buying from broadly the same pool. Materials that are genuinely restricted to one customer exist but are the exception, usually secured by paying for exclusivity for a period.
This is why the price of a product correlates so weakly with the cost of what is inside it. Two products can share most of their material inputs and differ by a large multiple at the till, because the difference is not in the drum. That is the subject of the economics of a moisturiser.
Convergence and the price of the story
When products converge technically, the remaining points of difference are the pack, the narrative, the distribution and the price. Those are the levers marketing controls. So the more alike the contents become, the more is invested in everything except the contents.
That investment is real spending, and someone pays for it. It appears in the price of the product, alongside the retailer's margin and the cost of acquiring the customer.
- Contract manufacturers. Sell proven bases repeatedly with development already amortised
- Raw material suppliers. Set the direction of a whole category by publishing a starting formulation
- Brands with strong narratives. Capture a premium that is not attributable to the formula
- Shoppers who read ingredient lists. Can sometimes find the same construction for less, if they know what they are looking at
A description of a market structure. No claim is made about the composition, pricing or conduct of any specific product or company.
The constraints that narrow the field further
Even a formulator with no commercial pressure at all would arrive somewhere near their competitors, because the space of workable formulas is much smaller than the space of imaginable ones.
- Regulatory limits. Restricted substances have maximum concentrations, and some are banned outright. The annexes to the retained cosmetics regulation define the field of play for everyone equally.
- Stability. Only some combinations survive three years in a pack, and those combinations are well known.
- Preservation. The list of permitted preservatives is finite and their working conditions are fixed by chemistry.
- Sensory expectation. Shoppers reject products that feel wrong for their category, so texture is effectively specified by the market.
- Cost. At any given retail price there is a narrow band of achievable material cost, and it excludes most of the interesting options.
Unlike anything else on the market
That the advertiser considers the product distinctive. Superlatives of this kind are frequently treated as obvious puffery, which is a category of claim that consumers are not expected to take literally and which is therefore not required to be substantiated.
If the phrase is presented as a specific factual comparison rather than as puffery, it becomes a comparative claim and does need evidence.
It does not mean the formula differs materially from competitors. It does not mean anybody has compared it to anything. It does not mean the base is bespoke, the actives unusual, or the manufacturing route different from the rest of the category.
A version of this claim that meant something would identify the point of difference and the comparison set: a named technology, a stated concentration, a specific delivery system, a granted patent. Once that is stated, it can be tested. Which is why the strong versions of this claim are rare and the vague ones are everywhere.
Why this is not the scandal it sounds like
It is worth resisting the pull towards outrage here, because the outrage would be misdirected. Convergence in a regulated manufacturing sector is a sign of maturity. It means the safe, stable, workable solutions have been found and are being used. Nobody is worse off because two lotions share an emulsifier system.
The problem is narrower and it is about information. Shoppers are invited to believe that price tracks formulation and that a story about a founder is evidence about a product. Neither is reliably true. Once you know that the technical distance between two products is often small, you can stop paying for distance that is not there, and you can also stop assuming that cheap means poor.
How to compare properly
The comparison that survives all of this is unglamorous and it is the only one you can actually run.
- Compare ingredient lists, not stories. Order gives you a rough sense of proportion in the top half of the list. Its limits are set out in what INCI ordering does and does not tell you.
- Compare pack format. An airless pump protects better than an open jar, and that is a real difference in what reaches your skin.
- Compare price per unit volume, not price per pack, because pack sizes are chosen to frustrate exactly that comparison.
- Compare over eight weeks on your own skin, one change at a time, which is the only trial whose result is about you.
That last one is worth more than everything else combined, and it is the one no brand can influence.
