I really love this. I use it just to brighten up my face because I've got a really dull, uneven complexion. I think you can see some results after the first use, but you definitely see a difference after continuous use. I will continue to buy this and other Mario Badescu products because everything I've tried has been amazing. I originally tried this in a sample bag that I got for free. I went to their website and input info about my skin and problems and they created a daily regimen for me and sent sample sizes of the products I'd need. They also included a guide to using the products properly so I could see results and I definitely did. I ended up buying a bunch of products after that because I fell in love. It's more expensive than drug store stuff but it's also way more effective. I've tried so many products over the years and these are by far my favorite ones.
