The mixing of the two components is quite complex if it must go fast times since. Also, I can not estimate right the right amount correctly, if I need very little (upper lip). The stuff applied almost corrosive to the nose with the stench. However, the hairs are pale in a moment. Aftermath: hair grow out faster, so there dark quickly, but also l ength r. Ouch. Its disadvantage is the very long hair. There are not only long hairs that have a disturbed, no. There are also many that one has never seen itself as one by automatically applying the entire surface is covered. On the product itself, it is not so. I tried already other such products (XYO) and the effect is the same. The price here is unbeatable compared to other competitors. I've had enough, this pack until today (in early December ordered). Here I use it only for the poor and my upper lip, a time for two to three weeks. But hair grows already relatively out after 1 1/2 weeks.
