If you want to be hair free, and stubble free for a week, you will have to go with a form of plucking, be it waxing, sugaring, threading etc…
Shaving will give you stubble in no time, and the lotions really only take the hard sharpe edges off the hair in the best cases. In the worst cases, they only lube them up to feel softer.
If you want smooth shiney legs, permanent removal is the way to go. After all, when will you find yourself saying, “I think I want the jungle girl look”?
Unless you have a fast electrologist, you can’t clear the legs before your trip, so you will have to decide if you want to be shaving with cold camp water, or take the rip of the waxer’s pull for the sake of your peace of mind untill you decide to do something more permanent.
By the way, I have been told that electrolysis on the legs is less painful than waxing. As a guy, I have never waxed, so I can’t say what the difference is. I have had students work on my legs however, and can vouch that even untrained people can do tolerable work on legs.
