Episode notes
Clinically Tested Is Often Marketing
- "Clinically tested" on cosmetics often means minimal, inconsistent testing rather than drug-level trials.
- Dr. Ranella Hirsch warns the phrase exploits consumer assumptions about rigorous clinical evidence.
Request Study Details Before Trusting Claims
- Don't assume brands will publish meaningful clinical data; ask for study size and methods.
- Verify whether studies are manufacturer-funded and look for independent peer review before trusting claims.
Dermatologist Tested Lacks Standards
- "Dermatologist tested" is amorphous and can mean anything from a friend giving approval to formal testing.
- Hirsch emphasizes disclosure of financial relationships matters more than the vague label.
