Great idea, terrible packaging
About 1/4 of the way through the bottle, it stopped dispensing properly. I'd get all moisturiser and no serum, or, more likely, all serum and no moisturiser. I'm now 3/4 of the way through the bottle (showing how long it lasts - I bought it 7 months ago) and the serum appears to be entirely used up. I can't tell if it would have lasted the whole bottle if the pump had been dispensing correctly.
Is it fantastic? Yes, when it works. It brightens and gives me a delicious glow. Would I buy again? No. Next time I'm investing in C & B serums and the straight-up dramatically different jelly.
