What the skincare industry knows and does not tell you

Dispatch 6 August 2026

The words on the pack were chosen by someone who read the rules first

A publication about the skincare industry rather than about skincare products. How a cosmetic is actually developed and who really formulates it. What a brand owns and what a factory owns. What a phrase is legally permitted to mean, and what would have to be true for the strong reading to hold. We name no brands, review no products and take no commission.

No affiliate links. Anywhere. Ever.

Not in articles, not in the newsletter, not behind a redirect. Affiliate commission is one of the incentives this publication exists to explain, so we have arranged not to need it. We are funded by a paid supplier register sold on disclosed verifiable facts and published alphabetically, and by newsletter sponsorship at a published rate with a written list of what the money cannot buy. Sponsorship cannot influence a single translation entry.

01

Who actually formulates the skincare you buy

The person who designs a cosmetic formula is almost never the person whose name is on the jar. Here is who does the work, who owns the result, and why you cannot tell from the outside.

Formulation
02

How ingredient percentages are chosen, and why the number on the front rarely means what you think

A percentage on a cosmetic pack is a marketing decision as much as a formulation one. What the number is measuring, what it leaves out, and when it is worth anything.

Formulation
03

What happens in a stability test, and what it is really protecting

Every cosmetic on sale has been through stability and compatibility testing. What those tests do, what they do not check, and why they shape the product you eventually buy.

Formulation
04

How a brief becomes a formula: the development pipeline nobody shows you

The route from a marketing document to a product on a shelf runs through bench work, pilot batches, scale up and a claims decision. Each stage changes the product, and most changes are commercial.

Formulation
05

Preservation, and why the least glamorous decision in the formula is the most important one

Any cosmetic containing water can grow organisms. How preservation systems are chosen, what the free from claims are doing, and why this is the decision a formulator will not compromise on.

Formulation
06

What a brand owns and what a contract manufacturer owns

The contract between a beauty brand and the factory that makes its products decides more about the product than any marketing decision. What is typically owned, licensed or withheld.

Manufacture
07

Why so many skincare products are nearly identical

Stock bases, semi bespoke formulas and a small pool of raw material suppliers make convergence structural rather than accidental. What that means for how you should compare products.

Manufacture
08

What a minimum order quantity quietly decides about the product you buy

Minimum order quantities set by factories and component suppliers shape the size, the pack, the shade range and the shelf life of the products that reach you. The number nobody markets.

Manufacture
09

Inside a cosmetic factory: what good manufacturing practice actually means

Cosmetic good manufacturing practice is a documented system covering people, premises, equipment, materials and records. What it requires, what it does not, and why batch records matter to you.

Manufacture

Packaging decides more than you think, and it is a formulation decision

The container is not a wrapper. It changes what survives inside it, how much you use, what the product can claim, and how much of the price you pay is not the formula.

Manufacture
11

What clinically proven is allowed to mean, and what it is not

The most persuasive phrase in skincare has no fixed definition. What a clinical study in cosmetics usually is, what the advertising rules require, and the questions that separate evidence from decoration.

Claims
12

Dermatologist recommended and dermatologist tested are not the same claim

Two phrases that sound interchangeable describe entirely different things. What each one requires, what neither of them means, and how to read them at the shelf.
