This is a beautiful essence, heavier than traditional first essences like the SK-II FTE. It hydrates well, but otherwise it really do anything special. I didn't notice any significant improvements to my skin while using this, and because it's slightly thicker than other essences, it might not be a good fit for those who like to layer on products.
