I purchased multiple products from Skinceuticals and decided to return one of them because it wasn't great. I returned the product over two months ago and have been waiting for my refund. I have called the customer service number no less than 12 times. I have chatted with their online support no less than 10 times and NO one can follow through what they say they're going to do. It has been incredibly frustrating. SO, you should know that even though the products might be great on some level, their customer service is horrific.
