This brand is very luxurious. I first tried the day and night serums when I received them as a sample in my order from Sephora. It did the job! I was hooked on the night serum's intoxicating scent. I had to have it. Then I went online to order: $85 an ounce! Seriously luxurious. And too rich for my blood. I have to admit I found it on eBay for much less. Luxury for less! That's the name of the game!
