I have been using this product for awhile now, so I feel I can make an informed review. This is a foam you apply to cleansed skin, less than daily, under any serums or moisturizers you normally use. It goes on slightly tacky, and I always want to wash my hands after using it. It takes a bit longer than my other face products to dry, but once it does I can't tell it is there. This may be a function of it being a foam- I haven't used a facial foam before. It does not have a scent. I was disappointed when I got it to find that you can't use it around your eyes, because I had really wanted to see if it had any effect on my wrinkles there. I don't have any wrinkles anywhere else on my face, so I can't tell the effect on wrinkles. I have not noticed a change in my face's pigmentation- dark spots, red marks , or general skin redness, which I been hoping for. Maybe with more use? What I have noticed is an incredible smoothness to my skin since I began using it. It helps a little with clearing acne, but not enough to not need another product. It does not entirely eliminate new acne, but it does help some. It also seems to be beginning to clear up the dark spots in my pores throughout my t-zone.
Based on my experience, I suspect if you use this product as part of a good skin care routine you will experience: exceptionally smooth skin, slightly less acne forming, slightly faster acne healing, and, over time, clearing of the dark spots in your pores.
