Our editorial standards
We help readers understand skincare claims before they decide what to buy. Our articles separate a product claim from the evidence that supports it.
How we assess evidence
We start with the skin concern and look for relevant clinical guidelines, systematic reviews and human studies. We describe evidence as strong, developing or limited only in relation to a specific claim and population. A laboratory result or ingredient study is not proof that every finished product works the same way. We explain study size, formulation, concentration and important limits when they affect the conclusion.
How we compare products
We check manufacturer information and the current pack where available, noting the market and date. Ingredient lists, package sizes, prices and availability can change. We compare products by routine role, full formula, directions, potential drawbacks and cost per 100 mL; sharing an ingredient does not make two products equivalent. If we have not tested a product ourselves, we say so. Editorial examples are not personalised recommendations or paid rankings.
How we handle cross-border rules
We use primary government and regulator sources for claims about restrictions. A useful alert identifies the jurisdiction, product category, relevant condition and source date. A name match on an ingredient list cannot by itself determine concentration, legal status or whether a product is safe for every person. We review regulation-sensitive pages when rules change.
Corrections and independence
We show publication or review dates and link to the sources behind material claims. Project Glow does not let a brand buy a better ingredient match or editorial conclusion. To flag an error or request a source review, email try@projectglow.skin with the page link and supporting information. We will correct substantive errors and update the page date.
Health information
Our content is general education, not diagnosis or treatment. Persistent or serious symptoms, pregnancy-related questions and medication choices should be discussed with a qualified clinician. The Project Glow web beta is for adults aged 18 or older; educational articles are public.
