The very first day I applied the serum my husband asked me what I had done different, that my skin was glowing. After now almost three weeks of daily application he said, "whatever you are doing to your skin, keep doing it, your skin looks amazing." It is pricey but thank you for formulating something that actually works. I struggle with a ruddy unbalanced complexion with some hyper pigmentation and your serum has helped dramatically. Thank you!
