Look at the ingredient list on an expensive serum. You will likely find something called a "proprietary blend" — a group of ingredients listed together with a single combined concentration. Inside that blend might be a peptide at 0.001% concentration, alongside glycerin and water that make up the bulk. The legal framework allows this. The customer cannot tell the difference. And the brand has a competitive moat: no one can copy what they cannot see.
This is the transparency trap. In most industries, customers demand to know what they are buying. In skincare, the convention is the opposite — brands guard their formulations as trade secrets, and customers are expected to trust that the expensive bottle contains something worth the price. The incentive structure rewards opacity. If a competitor knows your exact peptide concentrations, they can replicate your formula at a lower cost. If the customer knows your actives are at homeopathic levels, they stop buying.
Why Concentration Matters
A molecule's biological effect is concentration-dependent. GHK-Cu at 0.01% does not produce measurable collagen stimulation. At 0.5%, it does. The difference is not linear — many actives have a threshold concentration below which they are functionally absent. Listing an ingredient without its concentration is like listing a medication without its dosage. It tells you what is in the bottle. It tells you nothing about whether it will work.
Proprietary blends exploit this information asymmetry. A "peptide complex" might contain one active peptide alongside six inactive amino acids and a preservative. The label can name the peptide. The marketing can feature it in bold. But the actual functional concentration — the number that determines whether your skin receives a signal — remains hidden behind the word "proprietary." The brand gets the marketing benefit of the ingredient without the cost of including it at an effective level.
The Counterargument
The obvious objection to full transparency is competitive risk. If NeolabCare publishes the exact concentration of every active, a competitor can copy the formula. This is technically true. It is also irrelevant. A copied formula sitting in a warehouse for eighteen months is not the same product. A copied formula without the vacuum pump oxidises faster. A copied formula compounded at a different pH has different stability. The formula on paper is not the product in the bottle. The system — made-to-order production, cold-chain logistics, airless packaging, batch-level testing — is what makes the formula work. And that system cannot be copied from an ingredient list.
We list every active by name and function. We publish the concentration ranges that matter. We do this because we believe informed customers make better decisions — and because the long-term trust of a customer who understands what they are buying is worth more than the short-term advantage of hiding behind a proprietary blend. Transparency is not a strategy. It is a baseline. If a brand cannot tell you what is in the bottle, you should ask why.
