For a product with as much critical push as this one, I was (perhaps wrongly) expecting something amazing. The truth is that it didn't necessarily outperform other brightening serums that I've used before. It didn't do anything bad to my skin, but it just kept it looking as though I hadn't introduced anything new into the routine. To be fair, I've been using this product nearly every evening for about 3 months. This is an oil-type solution that absorbs relatively well, so long as you use the recommended 2-3 drops. Sometimes I've used 4-5 drops and found it was a lot more greasy than I'd like. I won't be repurchasing, but I'm glad I tried it.
