Good Serum, Poor Design [SEP] I like the product itself...it does moisturize and decrease fine lines. However, the entire package and product are in a foreign language so if you did not know how to use this product you have no directions.  It is also a very small quantity...it is in a medicine vial like one would see in a doctors office to draw up shots.  I also took me a minute to figure out how to get it completely open and attach the dispensing top that came with it.  After you pop the top of the vial you have to carefully removed all the metal around the rubber stopper without hurting yourself and then pull off the rubber top and pull over the top the dispenser.  It is a very poor design concept.  As for the serum itself, it is good.  It hydrates without being greasy or oily.  It goes on really smooth and you don't have to use much of it.  It doesn't come in a very large container so it doesn't take up a lot of space but I was really disappointed when I opened the box (which is much bigger than what is inside) and pulled out a small medicine vial.  Hyaluronic acid serum works like it should if you are familiar with it.  If you are not then I would avoid this product as a first time choice so you don't waste too much product and you receive directions that you can read.  I did receive this product at a discounted rate for my honest, unbiased review....I have given just that and my review has not been influenced by anything other than how I liked the product itself.
