Doesn't darken very much
When I was originally checking out this product, I was hoping for something that would significantly deepen my winter foundations. There are two colors: warm and cool, and it looked like warm was darker, but in fact it just warms up your foundations. Some people may find that it makes it too orange-y or peachy. Either way, it does get the job done, but not to the extent that I hoped it would. I recommend it if you just need your foundation to be adjusted to one shade darker, but not more.
