Have the product, I was very happy the first time, ordered again. Already when orders my eyes began to burn strongly, as to make (impure) skin on the face. ! Side effects that are not encountered in the first order I then the first tube, which was still present with a small residual compared with the second, and in fact: the ingredients have, albeit minimally changed! Here, the first purchase is degrees back by 3 months. That's too bad. However, I will try the gel further due to the here existing, mostly good reviews, but I am greatly confused already! And - absolutely eyes closed holding 30 s after application.
