Go to your family doctor and ask for allergy tests for Wheat, Soy, Barley, Milk, Egg, & Gluten (Celiac Panel). I am 99.99% sure a food allergy is responsible for Acne. In the mean time, go Gluten Free. If those test come back negative, keep track of what you eat/drink (ingredience or fruit) and get tested for those.
Ps for current Acne, try rubbing Banana peels or Neosporin on it & leave it on overnight.
,the photo below found on the internet is what I suffered from the age of 15 to 25 and since 25 I have been virtually spot free except for one or two breakouts a year.I found out the cause when I moved from my mothers home and her cooking,living on my own,I ate a lot of burgers and different fried foods,but to my amazement I got a clear complexion.http://www.healthhyp...infections.html
Blow is another photo of someone who has a different condition than mine, as I only ever got the one spot(the rest of my face having a clear complexion)this lady has clusters of them,so I don't know if my "prevention" not "cure" applies to both conditions.
I found the the cause of my problem as I said when I moved away,I wasn't actually searching for a cure it was by accident.http://www.acneprodu...es/cystic-acne/
So what I discovered was not that healthy foods(like my mothers) prevented spots,quite the opposite,neither was I applying cream or lotions or looking into medicines.I discovered with my now healthy complexion that I hadn't grown out of my condition as once or twice a year suffered a breakout and to this day still do,but what caused it?,fed up with fried food after a few months away from mothers,I decided to cook a tasty meal and bought a packet mix of sauce I remembered my mother used,a few days later a big spot,not reading anything into this,I had the same meal again a few weeks later,same result,gradually I had found my poison and later to discover that this chemical was found in many certain food products/sauces/drinks and even in medicines(I dread to think how many people are taking these medicines thinking that it's a cure,but actually is the cause).
So I know DEFINETLY what causes my spots and by avoiding these chemical have prevented not cured my condition.
Now(as I sit here with my clear complexion) I am most certainly not joining in with the above members in "I'm right you are wrong" or quoting medical facts or denials.I have eradicated my 21 year old daughter spots as she suffers from the same condition as me(but my son doesn't) and a handful of people who listened to my experience,but I am not labelling my self as an expert or know all,you can either read my personal findings with interest,maybe doubt or say it can't be true because doctors say different, I'm not bothered either way,just very happy that my daughter doesn't have a need to visit this website.
