Got a Question, a Find, or a Formula We Missed?

This is the place to reach us — whether you've spotted a product detail that looks off, found a formula we haven't covered yet, or just want to flag that a price or shade range has changed since we last checked. We also genuinely welcome notes from readers who've done their own deep-dive into an INCI list or tracked down a derm's commentary we might have missed. The more specific you can be, the more useful your note is.

A real person reads every submission. We can't guarantee a reply to every message, but tips that sharpen our research or correct something we've published go straight into our review queue. If your note updates a guide, we'll reflect that in the next editorial pass.
