ComfiSkin vs BeautyDecoded

BeautyDecoded is a French-language skincare app from a plastic surgeon with a big YouTube following, and its product scanner only works if you pay. ComfiSkin scans, explains and checks products against your skin for free, with no sign-up and no ads.

CONTAINS ADVERTISINGFrom its App Store age rating

The short answer

BeautyDecoded’s product scanner, personalised routines and ingredient blacklist are all Premium-only. Reviewers say the paywall appears only after a long sign-up. Its website says the business is funded “never on advertising”, yet its own App Store listing says “Contains Advertising” and its privacy label lists identifiers used to track you.

What that means: you’d be paying a monthly or yearly fee for the one thing a scanner app is for, from a company whose promises don’t match its own store listing. ComfiSkin scans and explains products for free, and never tracks you.

The scanner is the paid part

BeautyDecoded’s store listings put the product scanner, personalised routines and ingredient blacklist behind Premium. Its Google Play page quotes €39 a year, and the French App Store lists ten purchase options, including a monthly plan at €14.99, a weekly plan at €5.99, and a “30-day trial” at €49.99.1 Subscriptions renew automatically.

Reviewers say they only discover this at the end. When we checked, 8 of its 50 most recent French App Store reviews gave one or two stars, several about the paywall arriving after a 20-minute onboarding.3

Making people spend twenty minutes describing their skin before showing the price is a choice. It makes walking away feel like wasted effort. ComfiSkin asks a few quick questions and then everything is free: scanning, explanations, your avoid list and your routine.

What that means for you: the thing you downloaded BeautyDecoded for costs money, and you find out after you’ve invested the time.

“Never on advertising”, says the website

BeautyDecoded’s About page says its model “relies exclusively on our Premium subscription, never on advertising or commercial partnerships”.2 Its App Store listing tells a different story: the age-rating block says “Contains Advertising”, and the privacy label lists identifiers under “Data Used to Track You”, which Apple defines as data used to track you across other companies’ apps and websites.1 On Google Play, meanwhile, it says no data is shared with third parties.4

Three official descriptions, three different stories. When a company can’t keep its own promises consistent, it’s hard to know which one to believe about your data.

ComfiSkin has no ads, no tracking and nothing to reconcile. Your skin profile, shelf and notes stay on your phone.

What that means for you: you can’t be sure what happens to your data in BeautyDecoded. In ComfiSkin, it never leaves your phone unless you back it up yourself.

A personality, not a neutral tool

BeautyDecoded is built around its creator, Dr Sylvain David, a plastic and cosmetic surgeon in Nice, and his YouTube audience.2 The site says it evaluates products “the way a dermatologist would”, though its founder is a surgeon rather than a dermatologist. One reviewer also noted that blacklisted ingredients still showed up in recommendations.3

ComfiSkin isn’t built around anyone’s channel or opinions. It explains what each ingredient does in plain words and checks the product against the skin type, concerns and avoid list you give it, every time.

What that means for you: answers based on your skin and the label, not on whose videos you watch.

What to do if you’re trying BeautyDecoded

  1. Check the price before you finish onboarding. The scanner needs Premium.
  2. If you started a trial, check when it renews. On an iPhone, go to Settings, tap your name, then Subscriptions.
  3. Scan your products in ComfiSkin instead. It’s free, in English, and doesn’t track you.
