Thanks for your quick response. … Just received my C Serum (2nd bottle) and I love it. I can see some improvement in the evening out of my skin. … Some of the dark spots have also lightened. By the way your moisturizer makes my face feel moisturized for the entire day and you know how dry it is over here (gets into the nineties, Fahrenheit and above 33 Celsius in the summer time and it’s inland).
