The K-Beauty Truth Bible

Korean skincare comes with big promises: salmon DNA that “rejuvenates,” snail slime that “repairs,” 500-hour aged ginseng, sunscreen that’s “better than anything in America.”

We read the full ingredient lists, the brands’ own test claims and the published studies, including who paid for them. Here’s what holds up and what’s mostly a story on the front of the bottle.

Inside you’ll find:

How to read any ingredient list in 60 seconds, including how to find the 1% line and the 1,2-hexanediol trap

The Korean sunscreen scorecard: 20 products checked for UV filters, and why 8 didn’t list them at all

Snail mucin, investigated: 10 products compared and the only two trials we could find

PDRN, investigated: why most of the science is about injections, not serums

SK-II vs Sulwhasoo: 7 ingredients vs 50, and where the ginseng really sits

Lip masks: 16 balms checked against the dermatologists’ avoid list

How to spot fakes and shady sellers

Sensitive skin and patch testing, the AAD way

A simple, honest routine, in budget and premium versions

5 printable checklists, a glossary and 27 sourced endnotes

Our promise: no brand paid to be included, and the ebook contains no affiliate links. We didn’t test products on our own skin. We read the evidence and tell you exactly what it shows, and what it doesn’t.
