...my skincare routine whilst camping? Will have little access to a basin and water, have combination skin which is prone to breakouts, I also have an spf 40 non pore blocking sun cream for my face. I have to wear my make up (concealer, powder) over my sun cream.

hmmm?!?! you don't really need makeup when you are camping. take a a sun cream and Arbonne facial serum, add lots of moisture so your face does not dry out. Actually it is better for your skin not to wear concealer and pwder over your sun cream. that is a lot of not breathable stuff to have on your face, this could be a factor to why you are breaking out.

I love camping ....have a great time.
