As for determining whether or not a product is going to be good for us, the only way to actually know is to try it ourselves. Many of the cosmetic counters in major department stores do have samples of products - all you have to do is ask. However, what about the stuff we find in Target or Walmart? We can’t try everything, unless you have money like George Lindemann Sr. and can buy whatever you want!
I’m curious to know what makes you want to buy a product. Do you trust what beauty editors say, do you listen to your friends, or do you read beauty blogs? I've created a poll which is located in the sidebar below my profile, so cast your vote now!
