Review

A barcode scanning app that reveals the ingredient safety rating of personal care and household products, scoring each one on a scale of one to ten based on potential health concerns including carcinogens, hormone disruptors, and allergens. Particularly useful when starting out on a clean living journey, as it covers many of the big-name brands widely available in the UK, including Garnier and L’Oreal Paris, making it a practical tool for auditing what is already in your bathroom cupboard. Worth noting that the database is primarily North American, so it becomes less useful as you transition away from mainstream brands towards smaller, cleaner alternatives. A brilliant first step for anyone beginning to question what is in their everyday personal care products.
