... Enthaaren always hurts a bit! Well, I would not know how much unhealthy chemicals indoors, however - it works beautifully. I bought the product already 4x and am satisfied. When it warms more than 4x in the microwave, the consistency is a bit strange liquid over time. That is not so in the beginning. But since I usually after 3 or 4 treatments the container have empty, that's no problem for me. It works, is also well suited for beginners and with a little baby powder on your skin - before the waxen - it is also bearable. ;-)
