Per another pinner: Works: "Made myself a little mixture of 1 part apple cider vinegar, 3 parts water and let it sit. Then with a cotton swab I rubbed the mixture across my face, let sit for fifteen minutes and rinsed with cold water. I then took a Q-tip and placed the mixture on the large pimple on my forehead and let stay for the night. Do you want to know what my forehead looked like in the morning? It was PERFECTLY clear."
