Research notes
The reading behind every claim.
We did the research so you don't have to — but here it is anyway, in case you want to. Each note shows our working, names its sources, and tells you where the evidence is thin. No claim on the front page that isn't traceable back to one of these.

We traced the viral "5 grams of plastic a week" stat to its source. The honest verdict: young science, real uncertainty — worth neither panic nor a sales pitch.
Non-nano mineral sunscreen, and the white-cast problem →
"Non-nano" and "no white cast" pull in opposite directions. The trade-off most mineral SPF brands quietly make — and the one we will.
