Evidence

Human Efficacy Reports on Finished Skincare Formulas

Most evidence in this industry is about ingredients. Ours is about the product you actually buy.

The difference

A raw material test is not a product test

A raw material supplier tests a raw material. That tells you the ingredient did something in a laboratory. It does not tell you what happens when that ingredient is formulated with eleven others, at a different concentration, in a product someone actually puts on their face.

A human efficacy report measures the finished formula, on people, over time. That is a different and much harder test — and it is the one buyers almost never get shown.

Measurements

What ours actually measured

The measurements below come from a 28-day human efficacy study with instrumental measurement, run by an accredited third-party laboratory. Subjects were measured at baseline, ten minutes, day 7 and day 28.

Acne redness area (measured spot)

−43.84%over 28 days

Eye-corner wrinkle area

−32.18%over 28 days

Total elasticity R2

+19.26%over 28 days

Subjects

33 / 31volunteers, two formulas
Every number above carries the three things we require: the site, the duration, and the percentage. We do not average different wrinkle sites together into a single headline figure, and we do not extend a result measured on one part of the face into a claim about the whole face. Further measurements are set out in the full report, available to buyers on request.
Due diligence

How to read any supplier’s numbers

Three questions separate a real report from a decorated one. They work on us too — ask them.

QUESTION 01

Was the finished formula tested, or only the raw materials?

Ingredient test data is not product data. If a supplier can only show you a material specification sheet, you have not seen a product test.

QUESTION 02

Which site was measured, and after how many days?

“Reduced wrinkles by thirty percent” is unreadable. “Eye-corner wrinkle area, day 28, minus thirty-two percent” is a measurement.

QUESTION 03

Who ran the test, and on how many subjects?

A named third-party laboratory with a stated protocol and a stated subject count is verifiable. An internal claim is not.

Access

Ask for ours

Send us the product you are looking at. We will send you the report alongside the quotation — not instead of it, and not after you have already paid a deposit.

Efficacy figures relate to the specified measured sites and time points. They are not a claim about permanent results, and they do not transfer to formulas we have not tested.

Next step

Tell us three things and we will send a quotation.

Which product, the quantity, and your destination port or city. That is everything we need to price your order properly.
