When I first purchased this product, I must say, I was a little unsure what to expect. With Vitamin C Serums it seems to be a hit or miss. Especially a product you cannot see, feel, or smell, at a higher price point than some of the others I've seen. This product is a must buy! I am incredibly impressed with the way it makes my face feel! It has a thicker consistency than a lot of the other serums that I've tried and I honestly thought it was going to leave a film or residue, but it absolutely doesn't. The thicker consistency really helps to ensure a full and mess free application! It also really helps you to control exactly how much product you put on your face and minimizes waste. The smell is far more pleasant than many other serums like this that I have tried! I've been using this product for almost 3 weeks now. It feels brighter and looks incredible without makeup which is just amazing! With acne prone skin, this hasn't been the case in a very long time! If you are on the fence about buying this product, just go for it! It's absolutely worth the investment!
