Methodology · Benchmark v1

The fixed, public test behind every Asli Score.

Built the way AI models are benchmarked: everyone takes the same test, results carry their sample size and a version number, and nobody can pay to change them. Results are what people report about their own skin and hair, not lab claims.

1 · Grouping

Products only compete with their own kind

Every product has an area, a type and a main active ingredient. A leaderboard is always one type, so face washes only compete with face washes. The active is a filter inside the board, and brand is never its own board.

Example

1AreaFace
2TypeFace wash
3ActiveSalicylic acid
4ProductBrand A Salicylic 2% Face Wash

2 · The check-in

The same five-step scale, every day

Each day people answer 3 to 5 one-tap questions picked from the products on their shelf. Every answer uses the same five steps, where the first is best. Each type is judged on what it is meant to do.

3 · Ranking

Evidence beats luck

Products are ranked by the low end of a 95% confidence range on the share who improved (the Wilson score). Five out of five sounds perfect, but it is five people. One hundred and eighty out of two hundred is far more certain, so it ranks higher.

Product X · 5 of 5Ranks lower

100% improved · likely 57–100% · ranked on 57%

Product Y · 180 of 200Ranks higher

90% improved · likely 85–93% · ranked on 85%

4 · The rules

Who counts, and when a result is published

Real, verified people

Google sign-ins who chose to contribute. One real account per person.

4 complete weeks

Check-ins on at least 4 days of each week, back to back.

Against your own start

Weeks 3–4 compared with week 1. Half a step on the scale counts as a change.

Only real problems count

No breakouts at the start? You are left out of the breakouts question.

One change at a time

If two or more other products started around the same time, the result is not credited.

20 people to publish

Below that, only the head count shows. A small group can never reveal one person.
