how or if I should use aldera

I am a female, 56yrs.old and work outside selling cars.  I was diagnosed with pre-skin cancer and given a sample of Aldara {starter pkg single use} and told to use, no prescription necessary.  I was then visited by a estitition who suggested her treatment.(chemical peel) and and wait to use the aldara during the winter.  I did 3 treatments $85.00 each.  I still have the small scab on my nose.  it comes and goes. I have a new scab on the other side of my nose.

I quit my work because of exposure outside and still have the starter pkg.  Is this sufficient and is this the way to go.  Do I simply dot it on the 2 scabs only.  The car dealership has discontinued my insurance so I dont want to visit a doctor just yet if this Aldara will help.
