About The Diary

Kristi Kay

Who's behind this

Hi, I'm Kristi Kay — a chemist by training and a lifelong student of the everyday products women rely on. I started this diary because I kept finding two things in the same review: marketing claims that didn't match the science, and science that no one had translated into something a real person could act on.

What you'll find here

  • Honest reviews. When I test a product I tell you what works, what doesn't, and what no one else seems to mention.
  • Ingredient deep-dives. The chemistry behind the hype, in plain English.
  • Practical guides. The closet, the routine, the wellness habit — what to keep and what to drop.

How I work

I buy most of what I review. When a brand sends me something, I say so up front. Affiliate links may appear in some posts; full policy on the Affiliate Disclosure page. I never let an affiliate relationship change a verdict.
