Why Didn’t It Work?

Inside the Hope Economy of Skincare

PREORDER • SHIPPING & DELIVERY NOVEMBER 2026

Why does skincare work for some people and not others?

Why Didn’t It Work? examines the gap between what skincare promises and what skin can actually do with a product when it arrives. It is about context, biology, capacity, and the information we have been missing.

The first ten chapters are available to read free on the Proof Positive Skin Care Journal. The complete book brings the argument together in one place, continues beyond those ten chapters, and includes the notes and sources behind the work.
