Just a quick glance and you know where your favourite product stands. Ingredient details: By clicking on an ingredient, you will quickly find out if it's suitable for you. Sources and studies: For those of you, who want to know more, there is detailed information on our website. How do we grade? First of all, we don't evaluate/rate products; we focus on the ingredients and their worst properties. A colour grading scale: different colours show how safe or harmful an ingredient is. The ground rule: Although the grading is primarily based on the worst property of an ingredient, we can't forget about the positive aspects and contributions. Sources: We believe in science! Our data comes from trusted sources and studies. Relevancy: We’re human and we update accordingly to our possibilities. If you find outdated information, we will gladly adjust it. Why GreenScan? Free for all: Yes, the app is and always will be free! Community: Actively participating is key - the more products you add to the database, the better the app can keep us informed.
