I see many posts on this Acne board, with thousands of views, but few replies, so I thought I would share my experience that may help you.
My daughter has had severe acne (face, shoulders, back, chest) for several years and she is now 18. She has tried almost every medication the dermatologist had to offer except the most harsh one, Accutane. She has tried topical creams, facial cleansers, and oral supplements. Nothing worked.
What did happen, is that the antibiotics messed up her balance of gut flora, causing an overgrowth of Candida yeast which has gotten so bad that it has caused other symptoms, interfering with her daily life, including insomnia and pain set in so bad, that Morphine didn't even work! Sickness has gone on for almost a year now. The lesson in this is, if you are going to use antibiotics, you should be on probiotics. But I would further say, that taking natural products is better for your body.
Last week, I took her to a Naturopath who uses "BioMeridian Biofeedback".
This technology found many problems. I want everyone out there to realize that you may not have "just acne". There could be other underlying health conditions that need to be treated before you will rid yourself of acne.
I strongly recommend this form of Biofeedback to assess your whole body health. This means there is not a one-product-fixes-everyone solution.
In my daughter's case, I was surprised to learn that parasites under the skin are producing a bacteria that is causing acne!!
So the Biofeedback shows the specific product that will work with her body to kill off the organisms. I wish we had saved ourselves years of trouble and expenses by doing this Biofeedback. I hope that sharing this will help many of you!
