A good chunk of a beauty editor's job is trying new products, so you can only imagine just how many are tested per year. That makes them a pretty credible source when it comes to knowing what's good. (It's a responsibility they take on, so you don't have to. You're welcome.)
Everything from sheet masks to moisture mists to dry shampoos and back are tried, reviewed and stored in that section of their brain made for beauty products they can't live without. Are they addicting? Only in the sense that once you start using them you won't be able to stop.
If you're interested in flawless skin, moisturized lips or voluminous hair, head to the gallery for all the addicting products you (technically) could live without, but why would you want to?
