Absolutely worth it!
I've been using this product on and off for the last few years, and I see an almost immediate difference. Within one day, my skin has more of a glow to it and fine lines are slightly less noticeable. I am only 28, so I don't have a lot of issues with that to begin with, and I also have a serious skin regimen otherwise, but it is incredible to see. I only use 1 TBSP per day and that goes a long way.
