    Wonderful serum

    "This serum is so soothing and adds a noticeable glow to my skin. As someone else mentioned, if you are only going to do 1 BR serum, this is the one."

    Je (5/5)

    Comes in it’s very own Jewelry box

    "I just bought this and I can’t recommend it yet. But I can say that the way it’s packaged is way over the top. This is expensive and I’m beginning to think that half of the price of the product goes into the packaging. It comes in a velvet lined, very nice very expensive, hinged polished, high gloss white solid jewelry box!!! Honestly, this is such overkill it’s ridiculous. I hope I like the product but I don’t know if I’ll buy it again because I think I’m mainly paying for the container it comes in."

    "I just purchased this. It is great. I recommend it."

    Holly T. (5/5)

    Le Grand Serum

    "I have been experiencing very dry flaky skin in certain parts of my face despite hydrating efforts. Believe some of this is related to internal digestion issues and medication. I purchased this serum and within 2 days my flaking was gone! I am using this in conjunction with my other BR products - but this is a "must have"!"

    Cynthia R. (5/5)

    The BEST!

    "I absolutely love this serum! I use the Lait VIP O2 cleanser, then the Lotion P50 PIGM 400 toner, then Le Grand Serum. I have gotten rid of all my other products. No need for them with this incredible serum that does it all. A little goes a long way. Large bottle will last months!"

    Linda G. (5/5)

    Lovely

    "It feels fancy to use just because of the gold bottle! This stuff does a bit of everything for me. I am dry and dehydrated and when I use this finishing serum my skin feels almost fixed. . . I'm smooth, glow, plumped up and just look good!"

    "I use it with la grande creme. My skin regained some of the “glow” It Famously possessed during my teens, 20s & 30s and seemed to have lost mid 40s. warmly recommend ."

    Yaffa K. (5/5)

    Wonderful stuff!

    "I love my Le Grand Serum because its light and doesn't break me out. Living in Oklahoma is hard on a women's face as we either have blistering cold wind or cooking hot sun with wind. Really not a lot of in-betweens. I use this each morning under my sunscreen and it doesn't cause me to be oily."
