I used about 1/3 of a bottle before accidentally forgetting it at a hotel sadly. I had to repurchase it right away. This essence helps my skin stay hydrated and look much smoother. The packaging is nice with the frosted glass bottle.I love how this does not have a strong smell like the SK-II one. I can't stand the smell of the SK-II essence, while this one has a light scent, it is not as strong or overwhelming as the other. I have used quite a bit of this stuff since I love it. Highly recommend.
