Welcome to Mimi Decodes Skin

Human application test results, explained. Understand what cosmetic claims measure, how they are tested, and what the numbers actually mean.

K-beauty products often come with impressive claims:
“Pore volume decreased by 00%.”
“Skin hydration increased by 00%.”
“Skin elasticity improved by 00%.”

But what do these numbers actually mean?

Mimi Decodes Skin was created to make cosmetic human application test results easier to understand.

We explain how common cosmetic claims are evaluated in human application tests, including the test methods, measurement conditions, evaluation parameters, and instruments used to obtain the results.

From measurements of skin hydration, pores, wrinkles, elasticity, skin tone, and other cosmetic properties to the instruments and evaluation methods used to obtain these results, we break down technical information into clear, consumer-friendly explanations.

Our Editorial Philosophy

Clear, Not Complicated

Cosmetic testing can involve unfamiliar instruments, parameters, and technical terminology. We explain these concepts in plain language so that you can understand what a test actually measured without needing a scientific background.

Data in Context

A percentage on its own does not tell the whole story.

We look at important details such as what was measured, how it was measured, when it was measured, and under what test conditions. This helps put cosmetic claims into their proper context.

Objective Interpretation

Our goal is not to tell you whether a product is “good” or “bad.”

Instead, we explain what the reported human application test results show, what the measured parameters represent, and what should be considered when interpreting them.

Focused on K-Beauty and Cosmetic Claims

Mimi Decodes Skin focuses on the kinds of claims commonly found in K-beauty and global skincare products, helping consumers better understand the testing information behind the products they see online.

The goal is simple: to help you read cosmetic claims with a little more confidence—and a little less guesswork.
