I have the same problem. I found out when I went for my female exam that I have a hormone imbalance and that my oil glands over produce which is causing most of the cysts. I was on the pill for a while and went off when I wanted to get pregnant. The pill helped, but I've always tried holistic solutions to things that didn't have "CANCER" written all over them. I nursed both my kids to better mine and their chances against cancer. Then I came across a hormone cream. I use the one that Arbonne puts out and after about 2 months on it I maybe got one cyst. It's all natural but that doesn't mean it's all safe either, I know there is debate about black cohosh but I feel this is a safer alternative. Beside that time of the month is not as painful either. Other companies put out the same type of product also but I like the Arbonne it's called phyto prolief for hormone imbalance. It's air tight which means it doesn't go bad and it is all pre-measured. You count 12 days from the first day of your period start and use it for two weeks. I used it 2 times a day for the first month and then just once a day after wards. I figure it comes out about 10-15 dollars a month which is what I pay for the pill and it's safter.
Also I've been reading a lot on the gallbladder and liver recipes on this site. Like the other respondents have said and I'll be trying one of those to see if it helps. I still have breakouts, nothing like I did. I was so bad I looked like I had a beard of scars going from one side burn to the other and my chin has ingrown hairs which doesn't help along with light facial hair. I'm doing a lot of cleansing to clear my body, since I've been reading that your skin is a major filter for toxins and no a days Acne is at an all time high. That's got to tell you something right there. So I'm going to try the liver cleans and see if it works, I'm sure it will take some time but if you are interested in the results I'll let you know.
By the way when I was pregnant I ate healthier and drank a lot of water and because of being pregnant and nursing I was told it kept my hormones in balance. My face was completey clear and healed.
My first suggestion would be to get a blood check for hormone levels. Then if nothing comes of that I would do the liver and gall bladder cleanse which doesn't seem too bad, there is one they suggest here that is a one day thing, but I'm sure you'd have to do more than one to get results. At least that's my thought, I've learned to not get my hopes up that way I won't be disappointed.
Good Luck! Sorry for the long write, I just really feel for you.
