good serum poor design [SEP] i like the product itselfit 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 quantityit 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 do not have to use much of it it does not come in a very large container so it does not 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 do not 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 reviewi have given just that and my review has not been influenced by anything other than how i liked the product itself
