Methodology
Today's reports review labels and public sources. No product in this category has TPR lab data yet; lab checks come only after validation.
Phase 1 · Today
Step 1
Label Review
We document the ingredient list, amounts, warnings, certifications, and claims shown on the product label.
Step 2
Public-Source Review
We compare the label with manufacturer disclosures, regulator notices, recalls, and other public evidence.
Step 3
Evidence Summary
We publish what the available evidence supports, mark the report as label-only, and explain what remains unknown.
Phase 2 · Planned
These steps are a build-out plan, not a description of current product reports.
Step 1
Method Validation
The lab and each method must be validated before any product result is described as lab-backed.
Step 2
Retail Sampling
Future samples will be purchased from normal retail channels and logged with product, lot, and date details.
Step 3
Validated Lab Checks
Targets under validation before any lab-backed report is published.
The final list will depend on the category and validated method.
Independence pledge
We accept $0 from the brands we review.
Member-funded. No advertising. No free samples. No sponsorships. That keeps the product review independent.
Full methodology
Current label review, lab build-out, and planned reporting rules.
We review sunscreen labels and public sources, and clearly show the evidence behind each report.

In-house lab in build-out
Selected claims and contaminants will be checked using validated methods and method-specific reporting limits.
Step 4
Reviewed Results
Published lab-backed reports will state exactly what sample was checked, how it was checked, and what the result can prove.
Methodology
Current reports are based on labels and public sources. Lab checks will be added only after the in-house lab and its methods are validated; there are no TPR lab results in this category today.

Phase 2 · Planned
The lab and each method must be validated first. These are planned capabilities, not current product findings.
Planned step 1
The lab and each method must be validated before any product result is described as lab-backed.
Planned step 2
Future samples will be purchased from normal retail channels and logged with product, lot, and date details.
Planned step 3
Selected claims and contaminants will be checked using validated methods and method-specific reporting limits.
Planned measurement scope
Category-relevant contaminants checked at the reporting limits of a validated method.
Measured results compared with the specific claims that the validated method can evaluate.
Selected active ingredients measured when a validated category method is available.
Product, lot, sample date, method, reporting limit, and reviewer context published with the result.
Lab build-out
These are the quality and reporting targets for the in-house lab before product results can be published.
Planned scope
Planned step 4
Published lab-backed reports will state exactly what sample was checked, how it was checked, and what the result can prove.
