As expected, it's just a sample, so I cannot say if it works or can really brighten skin in the long term. The product was a little too sticky for my taste, I had to wash my hands after applying and my skin felt very tight with it on. I use a brightening serum and it doesn't have the same affect. It did have a nice smell and given it seems like a boutique brand, it may be good. But the sample didn't WOW me enough to switch out my current product.
