This serum has two sides to it. On the one hand it's quite sticky and does not absorb immediately. Also it has a really weird smell. On the other hand, it's super potent - it fades my hyperpigmentation and freckles, smoothes fine lines and reduces breakouts. The disadvantages are really significant, but I am ready to put up with them as long as I see the effects. It's already my second bottle and I think I'll keep repurchasing.
