I use EWG for EVERY single beauty or body product. The safety ratings, ingredient breakdown, ingredient concerns and other data allow me to make informed decisions on what products I want to use vs. what I should skip.
Another great EWG resource centered around your zipcode and the water you're ingesting through your local sources.

I use this amazing resource when researching ingredients in any product. Research, links and explanations accompany any ingredient you're interested in learning more about.
