Formula is good, but this is my third purchase to try to get the correct color match even after email help with a consultant. I purchased 02, 03, and 04...all too pink. They do not have any lighter shades that have golden undertones (even though 02 is suppose to be golden, it is not). If I try to get a shade that’s more golden, it will be too dark. I didn’t return 2 of my purchases, but just tried to return my 3rd because I was tired of wasting money. They state they will deduct $4.95 for a return fee and just found out it will cost me $11 to ship it back. With the price of the refill purchase, there’s no point in trying to return. I understand this is a small company (so they can’t cover return shipping and charge a return fee), but beware of buying the wrong shade, because returning is not worth it. Money wasted.
