I've been using knutek skincare products for years now, always loving them. Just turned 40 and decided to add this one to my regimen. Been using it for 2 weeks, morning and night, and I love how it makes my skin look and feel. Very refreshed. I get compliments.
That said, I haven't seen much effect on my wrinkles or age spots, but will keep using and see. It was a good buy in any case.
