Since taking baby steps toward a cleaner, healthier lifestyle, I've been choosing different products and making more conscious choices. But, do you ever wonder just how clean some products are? Thanks to Think Dirty, you don't have to use much brain power! Think Dirty is an app that helps consumers make clean beauty choices. Based on a scale of 0-10, products are rated on the carcinogenity, developmental and reproductive toxicity, allergenicity and immunotoxicity of the ingredients. The lower the score, the cleaner the product. You can scan your current products or view the extensive database that's growing every day.
