I used a sample of this and I absolutely loved it! I apply this to my entire face in the evening, after my night routine. It comes with a handy pump which makes it hygenic and easy to use. The next morning my skin feels firm, hydrated, bouncy, healthy etc. I have a healthy glow and my skin does look whiter. But I feel like the whitening effect fades away quite quickly. One con is that it's a little sticky on your face, so you can't really lay on your side when you go to sleep. But it is possible! because the product sort of dries and doesn't smudge and smear over your pillow. I tried other masks for at night and those felt like having an immense layer of product on your face and with that you absolutely can't lay on your side. So I'd really recommend this!
