I have been reading a lot of posts about this product and I finally purchased it. It has galactomycces ferment so it's supposed to lighten / brighten acne scars and discolouration. I have only used it for a short period of time (about three weeks) but it already is visible that this product is brightening my skin. It's a great amount and great ingredients for  small amount of money and it also hydrates my skin. Will recommend it to everyone as a first essence.
