As I mentioned in a studio have a IPL treatment behind me who also went well, I, however, for reasons of cost switch now to a "home unit", I know that the treatment is carried out only with gel in the studio. So I ordered the gel with it and the device is working so very well together. In the beginning you have it weekly anwernden over 8 weeks, then submit larger proprieties (about 6 weeks). Works in general (in the studio) only with fair skin and dark hair. Handling is very simple. Manual in English only enclosed, I have it but then just loaded me down from the Net. The purchase price is a bit steep, but count the studio treatments together, he paid for itself soon.
