I started using honey as part of my morning facial routine at the suggestion of Crunchy Betty's ebook Food on Your Face. I pour some honey on my fingers and spread it all over my face. If I'm in a hurry I'll wash it off right away. If I've got some time I'll leave the honey on for 5 or 10 minutes while I do other things and then wash it off. It has been a great acne fighter for me along with my thyme toner I use before bed.
Beware buying your honey from a big-box store or pharmacy. Often times, it's not even honey.
Pasteurized honey is no good for your face. All the beneficial enzymes have been killed in the heating process. This is the honey you typically find in mainstream grocery stores. Often it's"laundered" from Asian countries to hide it's inferior Chinese origin.
Raw, unfiltered honey is honey that has been heated less than 115 degrees Fahrenheit, the official “raw heat” designation. It's been minimally filtered to remove some of the pollen, propolis, and wax. Where can you get the good stuff? I get mine at local orchards and farmer markets.
