Skincare claim benchmarks: the complete reference
Glow Benchmark maps published cosmetic claims to the methods and evidence behind them, covering sun-protection ratings, formula concentrations, photostability, clinical endpoints, and regulatory clearance across the United States, European Union, South Korea, and Japan.
Welcome to Glow Benchmark
Glow Benchmark exists for one reason: to make Skincare claim benchmarks easier to understand. You don't need jargon, gatekeeping, or a wall of conflicting advice — you need accurate information and a clear place to start. That's what you'll find here.
Everything is a free, research-backed reference. Each guide is written to give you practical, honest answers, and each one links out to the related guides around it — so you can follow a question as far as it goes without ever hitting a dead end.
Not sure where to begin? Browse the full library of guides and follow the links inside each one to everything related.
We keep our method simple and out in the open. Claims trace to primary sources, dates are honest — published and updated timestamps are real, and freshness is earned by revising, never stamped. When we're wrong, we correct it in public rather than quietly editing the record.
You can always browse every guide in one place, or read more about how Glow Benchmark works and who writes it on our about page. Wherever you land, the goal is the same: clear answers you can act on.
No hype. No trends. Just Skincare claim benchmarks, explained plainly.
