What 'dermatologically tested' should mean
"Dermatologically tested" appears on a large proportion of skincare packaging. As a claim, it is technically accurate when true and almost entirely uninformative as a consumer signal. This note explains why — and what a meaningful testing claim should contain.
What the claim actually says
"Dermatologically tested" means only that the product was tested under the supervision of a dermatologist or dermatological institute. It says nothing about:
- What was tested (patch test, in-use study, biophysical measurement, something else)
- How many subjects participated
- What the outcome was
- Whether the study was controlled or comparative
- Who conducted it and whether the methodology is published or auditable
A product can carry the "dermatologically tested" claim after a single repeat insult patch test (RIPT) on 20–30 volunteers showing no allergic reaction. That is a basic tolerance test — not an efficacy test, not a safety certification in the broader sense.
What meaningful testing looks like
A product with a genuine testing basis should be able to specify:
- The type of study conducted and the number of participants
- The primary outcome measured (TEWL, corneometry, visual scoring, self-assessment)
- The study duration and conditions
- Whether the study is conducted by an independent testing partner
- The claim it substantiates and whether that claim is on-pack
EU safety assessment vs efficacy testing
Under EU Cosmetics Regulation (EC 1223/2009), every cosmetic product placed on the EU market must have a safety assessment conducted by a qualified cosmetic safety assessor (Article 10). This is a mandatory requirement — not a voluntary quality indicator. A product that has undergone EU safety assessment has met the minimum legal requirement, not distinguished itself from competitors.
Efficacy claims — "hydrates for 24 hours," "visibly reduces pore appearance" — require separate substantiation: human volunteer studies, instrumental measurement or in vitro data appropriate to the claim.
Ambernay's position
Ambernay products meet EU safety assessment requirements as a baseline. We treat this as compliance, not a marketing claim. Where we make specific efficacy claims, those claims are substantiated by the testing behind the finished formula — not by extrapolation from ingredient data or unspecified dermatological oversight.
We communicate our testing basis transparently. If a claim cannot be substantiated to the standard described above, we do not make it.
