Not great for my sensitive skin
Personally this really hurt my skin (barrier). I tried it over my moisturizer and only on a few spots. It dried those spots out so much, that even after a couple of days i still had flaky skin. It also burned my skin a lot, which made me take the product off quickly. The reason I write this review is to let my sensitive skin people know, that even though it is marketed for sensitive skin, still be very carefull!
On the other hand my boyfriend, who seems to have a iron skin, really likes this product!
