My daughters recently came home from a summer activity with face paint on. I didn't have any cold cream to remove it I wasn't sure how I was going to get it off, Then I remembered my friend telling me to use baby oil to remove mascara and eye shadow. So I tried the baby oil on the face paint it worked like a charm even on the thick blue eyebrows.

Put some oil on a cotton ball and rub on the face paint. Use another cotton ball to wipe up the excess paint. Finish by washing your face with soap and water.
