This policy covers the DemythSkin browser extension for Chrome ("DemythSkin: Skincare Scores & Dupes").

What the extension reads

On product pages of sephora.com, ulta.com and amazon.com, the extension reads the brand name, the product name and the address of the main product photo that the page shows. It does not read your account, cart, orders, address, payment details or anything you type. It does nothing on other websites.

What it sends

To show scores, the extension sends the brand and product name to scores.demythskin.com. Like any web request, this includes your IP address, which our hosting provider may keep in standard server logs. We do not link lookups to a person, and we do not build a browsing profile.

What it stores

Four settings (show scores on Sephora, on Ulta, on Amazon; open the card automatically) are saved in Chrome's extension storage and sync with your Chrome profile. Nothing else is stored.

What it does not do

No accounts, no cookies, no analytics, no advertising and no affiliate links. We do not sell or share data with third parties, and we do not use it for anything other than showing scores.

Links

Buttons on the score card open pages on demythskin.com and scores.demythskin.com, which are covered by the website's own privacy policy.

Changes

If the extension changes what it reads or sends, we will update this page before the new version is released.

Skincare Ingredient Analyzer FAQs

Everything you need to know about our product scoring and ingredient checking tool.

What is DemythSkin and how does it work?

DemythSkin is an advanced free skincare ingredient analyzer/ ingredient checker / cosmetic ingredient scanner. Our AI reads the full INCI ingredient list of any cosmetic product and cross-references it with clinical data. We instantly break down what each ingredient does, grade the formula, and generate an easy-to-read report card so you know exactly what you are putting on your face.

Can I use this as a pore-clogging ingredients checker?

Yes. If you struggle with acne or breakouts, our tool acts as a strict non-comedogenic ingredient checker. We scan the formula for heavy waxes, comedogenic oils, and known acne triggers, flagging them instantly so you can build a truly acne-safe skincare routine.

How do the Efficacy and Safety scores work?

Every product receives a brutally honest score out of 5.0. The Efficacy Score measures if the product contains enough "Gold Standard" active ingredients to actually work. The Safety Score acts as a skincare toxicity scale, penalizing products that use harsh alcohols, volatile essential oils, or potential allergens.

Can DemythSkin help me find skincare dupes?

Absolutely. If a luxury serum gets a low efficacy score or has a terrible price-to-performance ratio, our skincare dupes finder algorithm will suggest highly-rated alternatives. We point you toward more affordable products that contain the same (or better) active ingredients.

Are these cosmetic ratings biased by brands?

Never. DemythSkin is a 100% independent clean beauty checker. We do not accept brand sponsorships to alter scores. A product's grade is determined solely by the scientific data backing its ingredient list.
