In review · 109
In August 2026 we re-audited our own published articles, against a stricter citation standard than the one that first cleared them.
42 pages went back to draft. They cover skin conditions, prescription ingredients, pregnancy, and teen skin — where being wrong costs the most. We did not find all of them wrong. We found that we could no longer show they were right, and that is not a standard we will publish under.
Each one returns when it clears the new standard, not before. The rest of this queue is work we have not published yet.
Articles roll out in batches as the audit clears them — categories below show what’s coming. For updates, follow Drop on TikTok.
