I am 22 years old and have suffered with acne for about 4 years now (Since after High school). I started off with a few zits here and there that I really paid no mind to. Eventually it started to get worse to the point where I felt ashamed & paid the dermatologist a visit & I was prescribed Minocycline as a result. I felt like this antibiotic was a blessing sent from the lord himself until I postponed my use of it to see if I needed it anymore, My acne came back more vicious than ever. I was now getting acne Cysts under my skin & the skin on my face was not only full of whiteheads but it was very oily & yellowish growths would appear. I also developed severe dandruff & itchy bumps on my scalp. The acne I was producing were scaly & oily and seemed like scabs. I was so disgusted with myself that I quit my job until I got the proper diagnosis of what this was. After going back to the dermatologist for a 2nd visit they diagnosed me with seborrheic dermatitis of the scalp & told me the regular about my acne: That i was just going to grow out of it with age.This answer really irked me because I really feel like my immune system is to blame. Another reason why i think so is because It takes me an eternity to get over a cold & I seem to be growing a couple of gray hairs (I know for a FACT genetics nor stress has no say in this case). I think that my immune system is bringing me down to tell you the truth. I had no other choice but to get back on minocycline. Of course my acne got better but for some reason I feel like whatever it is that is causing it is fighting back because even though i am taking the antibiotic I still have sight dandruff that does not seem to go away not even with the help of 2% ketoconazole shampoo. Im starting to blame my immune system for it all & im fearful that it has been weakened by so much antibiotic use. I must also mention that whenever I drink alcohol I get a pretty big flare up as well. ive drank alot in my teen years & i know that drinking causes immune problems as well so could that have something to do with it? If it does it would be weird because I know people who are alcoholics compared to me & have no skin problems whatsoever. I have stopped drinking heavy for awhile now but this internal problem still remains. I am a relatively healthy individual, I weigh 138lbs, I exercise almost daily, drink LOADS of water & I barely consume alcohol (Probably once every 4 months now) but im a victim to this horrific condition that lives inside me. I am grateful for minocycline but I dont want to take it for the rest of my life. Has my immune system been weakened to the point where it cannot fight of this acne causing bacteria? Can i strengthen it back up? Your feedback would be greatly appreciated....
