I purchased Premier Cru from Birchbox in October 2014. Just finished my bottle, a little goes a long way and I use on neck as well. I use 3-5 times a week regularly. This is the best cream out there, I have tried many high end creams.
You notice the difference immediately. Softness, reduced fine lines, firmness and exceptional hydration. I am very surprised this product has so few reviews!
My guess is because it isn't sampled, and the price is on the high side. I promise it is worth it and encourage anyone who wants a luxurious moisturizer with anti-aging benefits to try this cream.
