Cult product for a reason!
I was hesitant to buy this product at first - it was a bit unclear on whether this was more an exfoliant or serum. It seems from other reviews that people use it in different ways, but I use as an exfoliant and use 2-3 times per week as I have oily, congested skin. I love this product for that, but it also seems to smoothe and brighten my skin all over. This may not be for sensitive skin as it does tingle a bit. I find it much, much better than the many other exfoliants I have used. And the bottle goes a long way which is a bonus. I also recommend the travel size, its a great product to travel with.
