I recommend pulling a bristle bundle out of a cheap toothbrush, don't use the wand that comes with the mascara. For the few hour stubble you will need a compact.
"Unless you have pure black hair, I don't recommend pure black mascara alone. You might want to use black/brown, or a mixture of black black/brown either separately or mixed together depending on your preference.
�2 day stubble�
1. Apply mascara to the bristles (I usually do the darker one first)
2. Blot gently on toilet paper if needed.
3. Now this is the part that takes skill. Carefully poke on face. Refuel bristles when needed. Wipe the old mascara off the bristles if it starts getting to clumpy, and before using another color, if you want two distinct tones.

You'll want to use a fairly dark color probably, as you're trying to go for the under the skin darkness look.
Follow the directions above, only gently blot your face afterwards. Defiantly shave any facial hair first.
Next apply the face powder.
I don't just blot it on, smear it around a little.
It's okay if it wipes off excess mascara.
You'll want to brush a lot of the excess powder off too.
NOTE: Be careful to maintain some degree of speckled-ness, otherwise you'll look like you have grease on your face.
