Pure Hyaluronic Acid Serum 8oz and 1oz, Korean Skin Care Moisturizer, Anti Aging Korean Beauty (8 Fl Oz)

Is there alcohol in this?

Do I need to apply a moisturizer after using this?

My bottle was not full (only about 3/4 full). Is that normal?

I just opened my second bottle and i'm concerned. its nothing like the first bottle. it is thinner than water. i can't even put it on.
