the pump is very wasteful serum works nicely [SEP] i want to review this better i really do because the eye serum itself works quite well the problem is the pump unless you have eyes the size of an elephant you end up wasting a lot of this lovely eye serum because the pump will not allow you to dispense a small amount it actually pumps out at least three times what you can use this kills me especially as the product is a bit pricy i have tried a few different ways to get it out in a more efficient manner but because of the way that it is placed in the bottle and the type of pump it is simply impossible i will use the rest of what i purchased but sadly will not buy again because i feel as if i am throwing away money with the product waste as for the serum i have noticed a difference around my eyes no problems with sensitivity burning or drying of the skin
