Because you've been suffering for ten years, you might want to do the treatment once a day for about five days. The formulator of this treatment had his son (who had AC for 3 years) do this. Also might want to consult with a dermatologist on how to get your ulcers -- if they are ulcers -- to heal after you've ridded the infection.
And tonyjablony, if you're still reading, congrats on getting your cuts healed! And thanks for sharing!
