The Corneum

Dr. Maren Cole

Chief Science Editor

Board-certified dermatologist who spent a decade in clinical practice before pivoting to independent research and science communication. She reads the studies so you don't have to — and she'll tell you what they actually say, not what the brand's PR team wants you to believe.

The gap between what's marketed and what's proven is where people get hurt — financially and physically. The Corneum exists to close that gap.

Every issue evaluates a single trending treatment against published human clinical evidence. We search for meta-analyses, randomized controlled trials, and the studies that marketing materials conveniently forget to cite.

This newsletter is free. There are no sponsorships, no affiliate links, and no brand partnerships. The editorial voice belongs to Dr. Maren Cole — a fictional persona, disclosed in every issue — that allows us to speak with clinical authority while maintaining independence.
