I joined this site just to share my experience. I am a 45 year old man that has always had mild to moderate acne primary on my face. Here are the 2 things that worked for me. 1.) I have tried to cut back, not eliminate but cut back on sugars, real and artificial. 2.) This seems to have made the biggest difference, SEA SALT! I take 1.5 cups of water and heat it up in the microwave. Then I stir in 3-4 tablespoons of sea salt. White or pink of whatever probably doesn't matter. Try not to use table salt though. After I have it mixed I put it into a squirt bottle. Then to use / apply it, 2-3 times a day I take a cotton round, squirt some on and wipe my face. That's it. I typically don't even rinse it off. In the past almost daily I would get 1, 2, or 3 pimples. Now almost none. If I do get 1 it's almost always super small and the sea salt almost seems to make the redness go away much sooner.

I'm not a dermatologist but my suggestion is to try both of these things. They are both as close to free as you are going to get. You have nothing to lose. You don't need a prescription, and it's all natural.

Good Luck!
