Review (3/5): Serum great, dropper/bottle not.
I would have given it more stars except for the dropper/bottle. The serum itself, at least the bottle I received, was too thick for the dropper to be of any use. In fact, turning the bottle upside down even did not speed the serum up in exiting the bottle. I had to insistently tap the upturned bottle on my palm to get any serum out. However, the serum itself works very nicely for my skin. I will not be purchasing it again, though. It was too much hard work to access the serum and some serum even remained stuck within the dropper after finishing the bottle, so it felt like I did not get my money's worth, despite the reasonable product cost.
