The clinical layer behind certain reviews.
For product categories where editorial sensory testing is not enough — clinical-strength retinol, prescription-adjacent actives, LED and IPL devices, claim-heavy wellness supplements — Glow operates a partnership network with three independent Melbourne dermatology and cosmetic-science partners. They run lab-grade testing. We publish what they find. The credibility layer no other Australian beauty publication has.
Why we built The Lab.
Editorial product testing — six editors, eighteen months, structured rubric — is sufficient for the great majority of beauty products. Texture, tolerability, sensorial experience, day-to-day usability: these are best measured by editors using products as readers would use them.
For a specific subset of products, editorial testing alone is not sufficient. A retinol's irritation profile across Fitzpatrick skin types is a clinical question. An LED device's actual fluence at the skin surface is a metrology question. A wellness supplement's bioavailability is a pharmacology question. Asking editors to draw conclusions in these domains would be irresponsible.
The Glow Lab exists for these cases. The Lab does not test every product Glow reviews — that would be neither necessary nor practical. It tests the subset where editorial alone would not be enough to publish a defensible verdict.
Three independent partners.
Carlton Dermatology Group
Melbourne dermatology practice with a clinical research arm. Conducts patch-testing, irritation profiling, and 12-week clinical-photography studies across Fitzpatrick skin types I–VI. Used by Glow for actives-led skincare reviews — retinol, retinaldehyde, AHA, BHA, vitamin C in higher concentrations.
Southbank Cosmetic Science Lab
Independent cosmetic chemistry consultancy. Tests formulation stability, ingredient concentration verification, and packaging integrity. Used by Glow for premium-priced products where an independent verification of claimed actives concentrations adds material reader value.
Aesthetic Device Verification AU
Medical-device testing house specialising in at-home cosmetic devices. Tests fluence (LED, IPL), wavelength accuracy, treatment area coverage, and battery cycle longevity. Used by Glow for every device review priced above AU$300.
How a Lab-tested review actually works.
Editorial pre-test.
The category lead editor first tests the product through Glow's standard editorial protocol over six to eight weeks. Sensory assessment, application, tolerability for the editor herself — the same protocol any reader would experience.
Lab brief.
If the product makes claims that require clinical or technical verification (e.g. "0.3% encapsulated retinaldehyde", "120 mW/cm² LED fluence", "verified marine collagen peptide molecular weight"), the editor commissions the relevant Lab partner to verify the specific claim.
Independent testing.
The Lab partner conducts the testing without knowing the editor's pre-test conclusion. Results are returned to Glow with full methodology disclosure. We do not pay the Lab partner more or less depending on the result. We do not have any financial relationship with the brands being tested.
Publication.
The published review distinguishes between the editor's editorial assessment and the Lab partner's verified findings. Lab-verified data appears in a designated callout on the published review page, with the testing partner credited and methodology summarised.
Right of reply.
Brands receive 14 days notice of any Lab-tested negative finding before publication. Brands are entitled to provide their own verification data, which Glow will weigh against the Lab finding and publish alongside the review where editorially relevant.
What this means for readers.
If a product page on Glow displays the "Lab-tested" callout, you are reading a review backed by independent clinical or technical verification of the specific claim being made. If a product page does not display the callout, the review is editorial-only — also rigorous, but not lab-verified.
You do not need both. For most products, editorial testing tells you what you need to know. For the products where claim-verification matters most — high-strength actives, expensive devices, evidence-led wellness — Lab-tested coverage tells you whether the brand's claims are accurate.
What this means for brands.
Glow does not accept brand-supplied lab data in lieu of independent testing. If your product makes a clinically-verifiable claim and you would like Glow to consider Lab-tested coverage, contact the editorial team at [email protected]. The Lab partner's testing fee — typically AU$1,200 to AU$8,500 depending on the protocol required — is paid by Glow, not by the brand. Submission does not guarantee Lab-tested coverage; it guarantees consideration.
Brands cannot purchase Lab-tested coverage. They can request it. Editorial decision is final.
