Hmmm, I was super excited to try out this product and found the way it was packaged super interesting! However after using a few of the capsules I've come to the conclusion I don't really enjoy using this product. First, it feels quite silicon based hence the 'super smooth' feeling. Second, I haven't noticed any brightening effect or any improvement in general after using this product, other than my skin feeling smooth thanks to the silicon. Considering the price tag (luckily I got this on a sale) I'd suggest trying out some other Vitamin c Products such as the OST vitamin C serum or the vitamin C serum by klairs!
