I bought this soap, along with the Kolonia, for regular use while taking an acting class where I would need to perform live on camera for a casting director in NY. I have gotten satisfactory and encouraging feedback on how I have improved in my acting since and have noticed a turn toward more internal confidence during my short, informal experiment with regular use of these products. Of course, both the soap or Kolonia can be used to achieve a bright, "clean slate" feeling where I am more comfortable going on camera. Therefore, it is hard to tell which is more effective for this kind of prep. However, I enjoy the experience of using the soap more and even use it for shaving sometimes (it provides an effective shave and supports smooth skin!). I also notice there can be a subtle glamour effect with the soap, especially when I use it for shaving and all over cleansing. I'm usually "either put in a more uplifted mood after a bath with the soap or I somehow perceive I look more refreshed than before I used the soap." Overall, I would recommend this soap to anyone who appreciates the soap form in S and S products, or Regulus.
