Think Dirty is one of the most recognized ingredient-rating apps in clean beauty, and for good reason: it maintains a large database of products and flags potentially harmful chemicals so you can make informed purchase decisions. If you want to know what's in a product before you buy it, Think Dirty genuinely delivers on that promise.
What Think Dirty doesn't do is analyze your actual skin. It can tell you a formula contains a high concentration of fragrance, but it can't tell you whether your skin is dehydrated this week, what your natural undertone is, or whether the texture on your cheeks has improved since you switched serums. For that, you need a tool that works with your face — not just the bottle.
Rosee does both. You can scan a barcode or type an ingredient list to get a real compatibility score against your skin type and concerns — powered by OpenBeautyFacts data. And separately, Rosee's on-device face analysis measures hydration, glow, texture, tone (using CIELAB ITA°), dark circles, and redness without ever uploading your photo to a server. The two halves work together: understand your skin, then check whether a product actually suits it.
