I prepped my face with a good clean shave earlier in the day, then before application I used Ben Nye Hydra Cleanse to thoroughly clean my skin. Then I used Bemchmark's Derma Shield to protect it and let it dry for 5 minutes. I wore the appliance for about 4 hours so this prep and my sweating made removal a scoosh especially round the mouth. As you can see in the pics above I didn't cover my eyebrows, but I did add some vaseline as a precaution.
