How we work.

Estetly doesn't tell you what to think. Estetly shows you what the options that concern you rest on, and lets you decide, with your specialist.

This page explains our method: where our information comes from, how we qualify it, and where our role ends.

This is a health method. We apply it first to skin, hair and smile; the same rigour is meant to extend to the rest of your health (our manifesto).

1. We document and we cite. We don't validate the science in your place.

Estetly is not a medical authority. The evidence doesn't come from us: it comes from the scientific literature. Our work is to gather it, organise it and make it legible for your situation.

Every concern and every treatment rests on cited scientific sources: peer-reviewed journals, meta-analyses, major bibliographic databases (PubMed, Cochrane). You can trace back to the source.

The database, to date: 389 concerns mapped (88.8% tied to the international ICD-10 nomenclature), 135 procedures and treatments documented, connected to concerns through 1,049 associations with a published level of evidence, and 127 devices catalogued. It grows as new areas open.

2. A published level of evidence, for every procedure and treatment.

Not all options are equal. For every procedure or treatment requiring a practitioner, we publish a level of evidence on a scale from A to E, according to international standards of medical evidence:

A · Reference. Concordant meta-analyses and randomised trials.
B · Well-established. Robust, multicentre, replicated randomised trials.
C · Emerging. Smaller trials, consistent observational studies.
D · Experimental. Case series, preliminary unreplicated data.
E · Unproven. Anecdotal. Estetly references no option at level E.

You know at a glance what is solidly supported and what is less so. This scale applies to procedures and treatments; it does not apply to over-the-counter products.

3. Situated options: sequence, invasiveness, real cost.

An option isn't reducible to "it works or it doesn't". For every option, we set side by side what lets you read it properly:

where it sits in the sequence usually indicated by the evidence (first-line indication, alternative, last resort);
its degree of invasiveness (non-invasive, minimally invasive, invasive, surgical);
its duration, recovery, and price range on the French market;
for products, the real cost per day, not the price of the box.

4. Personalised, traceable reasoning.

Sothis, the Estetly engine, cross-references your profile (your skin type, your age, what you have already tried, your contraindications, and other factors specific to you) with the available information. It shows its reasoning and stays traceable: each element traces back to its documented source. Nothing is a black box.

5. A map of the body as your entry point.

You explore your concerns area by area on Vitruve, our 3D model. The body becomes an interface, not a form.

6. What the method doesn't do.

Our rigour has a boundary, and we state it plainly:

Estetly makes no diagnosis and prescribes no treatment. Sothis structures and guides; it does not assess your health.
Estetly is not a medical device and is no substitute for a consultation.
The medical decision stays with your doctor.
We sell nothing ourselves. When a link earns a commission, it is flagged (affiliation charter).

7. A database that grows and corrects itself.

Our database evolves. Eligibility data (coverage, social security) is shown as a first pass and refined continuously. If any information seems inaccurate to you, write to us at contact@estetly.com. Rigour is ongoing work, not a given.
