Description
Most skincare advice stops at the ingredient list. This guide starts where that stops.
A well-formulated active can reach your skin doing nothing. Not because the ingredient was wrong, but because of how the oil was extracted and how the product sat on your shelf.
I trained as a plant biologist and environmental scientist. I read skincare the way I read any claim, through the chemistry and the published research, not the marketing.
Five pages, no filler:
What the extraction method changes about what you are buying
Why a vitamin C serum turns brown, and what that colour is telling you
Which packaging protects an active, and which quietly wastes it
How to store each type of product once it is open
How to run a two-minute freshness check on anything you already own
You also get a storage reference table, a cheat sheet for the shop and the bathroom, and a short FAQs section. Built to be used, not just read.
Thrown out a serum without knowing if it still worked? This shows you how to tell.
