A 2023 Harvard Medical School study wasn't even looking for this. Researchers were studying allergen penetration, so they used radioactive tracers to track exactly where molecules travel after you apply a cream. They tested 50 luxury anti-aging products.

The lead researcher admitted they weren't expecting this finding. But the data was undeniable. These products physically cannot reach where aging occurs. The study was quietly published in a specialty journal. No media coverage. No industry response. Just silence.
