I dealt with acne for THIRTY (yes, 30!) years. I totally know the emotional stuff that people go through with acne---the doc kept saying "you'll grow out of it" but I never did. Anyway, I've tried everything from putting egg on my face to every medication available, to birth control pills, etc. I finally found a wonderful doctor who put me on thyroid medication even though my tests were within the normal range. Acne, fatigue, feeling cold, sometimes weight problems are all symptoms of low thyroid. For the very first time in my life, the acne is gone! I have been on this for about one year; it took a few months to adjust but I sure do feel better, and feel better about myself because I'm not trying to constantly hide my face. I just wanted share this info hoping that it may save someone many years of suffering needlessly!
