Unusual things I do to my face:

I use my fingers to apply pressed-powder eyeshadow, as it tends to adhere better as well as blend better.  My explanation for this is that I have oils on my fingertips.

I stick a Q-tip into apple cider vinegar and dab it on any blemishes I might have.

I use a moisturizer that smells like campfire/incense (St Ive's Renewal Cream, which has a picture of apples on the front... though it smells nothing like them.)

I sit with my face toward tea that's just brewed to steam it.
