The receipt is key and should state how long you have to return usualy 30 or 60 days. I dought that the store would keep your money for using 4 ampules. You know Sephora wants you to be satisfied and happy. Again don't attempt with out receipt,,, this is what the store will want to see.
Don't know about the return policy, but I just wrote a review on this after using it for all 7 days. I saw only minimal improvement, and was disappointed since it is so expensive. I went back to Crest's line of teeth whiteners, and tried their Advanced Seal - bought it on sale for $30. I used it twice a day for 2 days, and my teeth are MUCH whiter! I will finish out the 14 packet set, but I've already received compliments on my teeth.
So, if you're not really sure about this product, I'd recommend you pass on this purchase.
