This Review Title is Price performer with quality packaging and the content is: This serum keeps my facial skin moist.  I have been using it daily for a month, applying it before my moisturizer, and have not noticed any difference in my skin's appearance but I also know that facial products need to be consistently used for a dedicated period of time in order to see change.  With 20% vitamin C in its composition, it has one of the highest Vitamin C levels in  serums on the market.  The price is excellent as well.  I can buy four bottles of this serum for what I was paying for a product with a lesser vitamin C concentrate.  The dark brown glass packaging keeps the product from rapidly deteriorating.  Just ordered my second bottle..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
