I am on the fence with this one. I had purchased it in hopes that it would reduce my dark circles, acne scarring, and other hyperpigmentation. After several months, I can't tell if it had made enough of a difference to warrant purchasing it again.

It is potent, as in, it burns if it comes into contact with any cuts or open wounds. The thick primer like cream does need to be patted down, as rubbing it will cause it to flake off. The texture is matte, so it could be used as a primer, albeit an expensive one. The elegant looking tube is sealed enough, so that it will remain air tight for a long while.

Hard to say with this one. Was hoping for a miracle because of the high concentration of Vitamin C - 25%- but the results are not obvious enough to warrant purchasing it again.
