About SlipperSkin
Who we are
SlipperSkin is an independent editorial site covering skincare and makeup apps. We read makers' own product pages, compare features and pricing, and publish honest reviews with no sponsored rankings.
What we cover
SlipperSkin covers the decisions people make before trusting a beauty app: which ingredient checker to believe when two disagree, what an AI skin analysis actually measures, whether a shade match was trained on skin like yours, and what each app costs over a year.
- Ingredient checker apps, what each score is built on, and where the apps disagree
- AI skin analysis apps, what the camera measures, and what the maker has published about accuracy
- Makeup try-on and shade matching, shade ranges, skin-tone coverage and brand lock-in
- Clean labels, retailers and dupes, what each retailer's clean list excludes, same-size prices, and how closely a dupe's formula matches its original
- LED masks and beauty devices, what each device is cleared for in FDA's records, and what its companion app collects
- Ingredient files and brand files, 66 ingredients set against California's statute, the EU regulation, FDA's named list and EWG, and the ingredient-app verdicts for 48 brands' best sellers
Our methodology
Every product on SlipperSkin is evaluated across a consistent set of criteria: the price of each plan on the maker's own pages, what the app's score or verdict is built on, which sources it names, who owns the app and whether it sells products, and what it collects from your face and your data. We maintain a strict separation between editorial content and affiliate relationships, our rankings are never influenced by commission rates.
