I purchased a $60 concealer from them and it is so oily, it makes even waterproof mascara run leaving me with raccoon eyes. when I called to see if I could exchange it for something else, I was told that only unopened merchandise was returnable. When I told her the product did not work for me, I was told I should buy products from someone else before I buy them from Essential Derm Care. That is the most idiotic policy I have ever heard of. I will never buy from them again. What lousy customer service - do not use them.
