Think Dirty

Discover what's really in your cosmetics and personal care products with ingredient scanning and product ratings. Think Dirty is the independent source that empowers you to make informed beauty choices by revealing potentially toxic ingredients before you buy.

Scanning for safer products has never been simpler. Use barcode scanning or keyword search to instantly access ratings and ingredient breakdowns for over 850,000 cosmetics and personal care items from Canada and the U.S. The Dirty Meter® provides a comprehensive rating along with easy-to-understand details on ingredients, certifications, and health impacts—so you know exactly what you're putting on your skin.

Take control of your bathroom shelf with personalized tools designed to match your values. Save your allergen sensitivities and ingredient preferences to customize your shopping experience, and receive instant alerts when flagged ingredients appear in products you're viewing. Track expiry dates by entering the open date and shelf life, ensuring you never use expired cosmetics. Monitor your overall bathroom rating and watch your progress as you transition to cleaner products that align with your priorities.

Explore detailed ingredient information to understand usage, health impacts, and which products contain specific components—knowledge that transforms you from passive consumer to informed shopper. Access curated specialty lists including mineral sunscreens, SLES-free skincare, and vegan makeup options when you unlock premium features. Build personalized shopping lists to streamline your next beauty purchase across Amazon, Sephora, Well.ca, and other major retailers.

Your voice shapes the database. Upvote products that aren't yet rated, and Think Dirty will aggregate user feedback to encourage brands to submit their products for verification and rating. Found a product we're missing? Use your camera to scan the barcode and capture ingredients with OCR, then submit it directly—registered contributors receive discount codes for our beauty box subscription as thanks.

Think Dirty has been featured in Fast Company's World-Changing Ideas, TED Blog's Everyday Life Tools, Allure Magazine, BuzzFeed, and Glamour UK as an essential app for conscious beauty shoppers. Join thousands of users taking control of what goes into their personal care routine.
