I really feel for you....I know you are searching desperately but I don't know that you can prevent it. I tried everything and nothing worked. Just keep searching and don't give up. I realize my problem was not as bad as what you are going through and I count myself very fortunate that my skin did not scar badly even with those huge cysts. I still have redness and white spots after several years but with some work and good moisturizer the surface of my skin is smooth and being a female that's not so bad either as I can cover with makeup. Look at every aspect of your life every single product you consume (could you be allergic to hemp etc?) and every single product that is used in your household, ie detergents, cleaners, etc. And most of all do not loose your self worth. Having been there I have to say this: It seems the more it gets you down the worse it gets. Try looking in the mirror in the morning and seeing the asset you really are! You really do have a lot to give to this world. Keep your chin up and keep searching till you find the answers you are looking for.
