Disclaimer
What this site is, and what it is not.
Not medical advice
Everything on this site is general educational information about cosmetic ingredients and published research. It is not medical advice, it is not a diagnosis, and it is not a substitute for examination by a qualified professional. If something on your skin is changing, painful, or worrying you, see someone who can examine you.
No promised results
Cosmetic ingredients work in modest effect sizes over months, and individual responses vary. Nothing here promises a particular outcome for your skin, and no before-and-after imagery is used.
Independence
There are no affiliate links on this site and no paid product placements. Where a product is discussed, it was bought. Individual brands are not named negatively; categories of claim are assessed on the evidence behind them.
Accuracy
Sources are named so you can check them yourself. Research moves, and an entry reflects the evidence as it stood when it was written. If something here is wrong, say so and it will be corrected.
