This serum makes my fine lines disappears and leaves my skin soft and plump. You do not need much for your face, just 3 drops. It spreads easily and does not leave a sticky residue, which is great, as I hate when my face sticks to my silk pillow when I go to bed. It has no smell at all. You use a dropper to dispense the product so it is easy to use and never messy. Great hyaluronic acid serum in my opinion!
