Skin in need of a detox after overindulging during the holidays? Look no further than this super-simple peppermint detox mask that will help clear up acne while offering a few other surprising benefits. Here's how to make it: Start with your base, or carrier, ingredient—in this case, coconut oil, which moisturizes and kills bacteria at the same time.
