3. Think Dirty.
We’re all trying to pay more attention to the chemicals we put in and on our bodies these days but it can be a full-time job deciphering ingredients and figuring out what is harmful and why. Until now! You just scan the bar code or look up a beauty product in their database and Think Dirty will tell you on a scale of 1-10 how toxic it is. It lists all of the ingredients, explains what they are and explains which ones are harmful and why. But this makeup app doesn’t just leave you hanging, it suggests healthier alternatives too. We’re in love!
