Hi Lasthorn
You could always use some makes of insect repellant to use as a lubricant to shave with. As an experiment I tried 'Dr Johnsons Mosquito and insect repellent' roll on stick. It worked quite well except that it dried out slightly more quickly than a conventional shaving oil.
A good after shave moisturiser is also required whether using conventional soap or shaving oil.
Nivea Extreme Comfort After Shave Balm is excellent.

A razor such as the Avid4 shaving system with a shaving oil such as King Of Shaves Kinexium Shaving Oil Unmentholated 20ml, would be very compact and lightweight.
