What sources does Mira base its analyses on?

Mira's cosmetic analysis is built on the scientific evidence available for each ingredient in a product's INCI list. The goal is to give honest, verifiable information about how an ingredient may affect your health and the environment.

Where our data comes from

Mira draws on assessments from respected scientific and regulatory bodies, along with independent research. When weighing the evidence, we give priority to the most reliable study types — systematic reviews and meta-analyses first, then epidemiological studies, and finally laboratory data and expert opinion. Only the most dependable publications make it into our review.

How an ingredient's risk is assessed

Each ingredient is evaluated for the ways it may affect health and the environment: allergenic potential, irritation, effects on the hormonal system, possible carcinogenicity, and pollutant impact. From this it is assigned a risk level. In the product card, the sources behind each ingredient's rating are shown right beneath it.

A product's overall rating is set by its riskiest ingredient — that single component defines the band. One high-risk ingredient pushes the product into the red band ('Bad'), while a medium-risk one keeps it no higher than the orange band ('Poor'). Other risky ingredients lower the rating further, and in short formulas each one carries more weight.

The precautionary principle

Even when an ingredient is present within permitted limits and is considered safe by regulators, Mira follows the precautionary principle. That means we flag potential risks for you — including those still at the stage of scientific suspicion.

Accounting for exposure

Risk assessment looks not only at the ingredient itself but at the context in which it is used:

• how widely the population comes into contact with the substance;

• the typical concentrations in which it appears across different cosmetic categories.

Mira keeps its data up to date as new research emerges and international standards evolve.

The rating is Mira's opinion. The words 'Excellent', 'Good', 'Poor' and 'Bad' refer to the rating, not to the product itself.
