Hi M.,
I don't know what happened to me, but I can share this with you, I had the same cystic acne you are talking about. I had been on all the anti-biotics (which made other things worse if you know what I mean? :-() and the freezing of my face, and the topical ointments, the whole bit!
I got pregnant with my son and my acne problem got better.
I really don't know if was the pregnancy (changing of hormones or the supplements) But nevertheless, The other thing that I did, was add supplements to my diet.
There are several products that are safer than the antibiotics on the market and they are guaranteed to work or your money back!
If you want to know more, let me know.
Also try looking up: "resveratrol".
We have it in several products. We also have a 4-step Acne system(cleanser, toner, cream, and treatment) that costs less than $16.00.
God Bless!
J.
