Hey, y'all: 

I bought this products twice, I like the main principal ingredients: glutathione and vitamin C, they provide to my skin elasticity, brightening and nutrition. I use this when I stay awake or I'm so tired so I can see the incredible and fast result at morning or during the day.However, I have many problems with the liquid, when it arrives, it comes out, I think is due to the main packing of the ampoule. It's not secured at all, I recommend to check packing to solve this problem.Notwithstanding, I'll buy it again. 

Alfonso, 

Greetings!
