I'm really happy with this product. At first I didn't really see any difference but after more than 2 months (and I still have almost half of the bottle left) I can honestly say than my skin has become better. My face is brighter, my acne scars are lighter and the texture of my skin is also very nice. It doesn't have a smell which is great. I am really satisfied with the results but I have to say that I am using it with its sister the " Time revolution activator borabit ampoule"  which I think helped a lot, both are essential for me now :) I wanted to try the SKII Essence but now that I have found this product I'll stay faithful ( = great quality and inexpensive *^*! ) ~
