serum great dropper bottle not [SEP] 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 moneys worth despite the reasonable product cost
