This Review Title is No Serum, Just Liquid and the content is: Yesterday I tried making a serum.  I used 1 level tsp of the hyaluronic acid and 3.4 oz of water, this is a recipe I have used in the past.  It was only liquid, so I added a little more LMWHA to the mixture, it is still liquid today. The water was right out of the fridge, and it was shaken in a bottle and I waited for the bubbles to go away.  Today I will try the recipe given in the answered questions.  If it is any better I will change my stars. Made another batch this morning.  It also is just water, no viscosity to it.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.
