I'm sure everyone already knows this but this ampoule is probably the best bang for your buck. You get a huge amount of product for the price and I don't even need to dip the spatula in all the way for one use. I will probably have to slather it all over my body just to use it up before it expires! I find that this adds a lot of moisture into my skin and helps brighten it up ever so slightly. Nothing super drastic but better than nothing! I find that it stays somewhat sticky on my skin so I follow up with a lighter lotion during the day or a cream at night.
