Didn't believe the hype, either requested to remove the 1pc sample pouches for so many of my orders and ones that did come, threw out. Until i had the urge to give it a try on my overly sensitive skin one day. Found 2 samples that was just lying around, between those 2 x 1ml samples, used it for 4 days. Long story short, ended up kicking myself for throwing away all those past samples and bought myself 3 full sized bottles lol.
Every skin is different so make sure to test a bit before committing! Also my results were very slow (could be my skin, could be the smaller amounts i used) i didn't notice anything until probably on my 6-7th consecutive days of usage. i already have a pretty good skin to start with so I didn't expect much other than improvement on my skin texture. And that is what I got after a week of using! Brightening and lightening up small darker spots here and there is unchanged but we'll see how that gets improved in the next few weeks!
