I recently used parissa brand strip-less hot wax for my bikini line, and it worked pretty well. It was kind of messy, but I'm guessing that's just a feature of wax and my inexperience. The stripless aspect was kind of nice because it made the wax go further...I just remelted it and used it again. (Probably not the most sanitary thing to do, but whatev.)

I could never get sugar to work as well as the wax did...but the good thing is that with sugar you don't have that moment of terror where you've applied the wax and really don't want to rip it off...but don't have any choice. Yowch!
