I bought this to use with the serum and frankly, can see no difference. I currently have a quarter left of the bottle (storing it in the fridge) but cannot make myself finish it. An added con is the smell - super strong and my husband hates it! So cannot use it for my nighttime treatment. Ugh!

I have been using this for the last 3 months. It is pricey but the bottle will last for quite a long time. It has a nice feeling when you apply after a nightly cleansing routine and just before applying a moisturizer. The skin definitely feels softer. The only thing that does not work for me is the scent. If you are sensitive to stronger scents, test this one first.

I am a huge Tata Harper fan and use this before I apply my Concentrated Brightening Serum. Yes it's expensive, but it's amazing. I have hyper pigmentation and the combination of the essence and serum helps immensely. My skin feels so much clearer and radiant. I love it.
