hormonal acne

[beachmummy]

Hi Tania
I was interested to talk to you as I see that you are a hormone expert.
I have had acne since I was 12 years old (I'm now 34). I know for a fact that my acne is hormonal as it clears up totally when I am about 5-6 months pregnant and stays clear until after I give birth. Just to be clear - pregnancy is the ONLY thing that has ever had any effect on my skin. I have tried every medical and alternative therapy under the sun. My acne is not caused by stress or diet and I don't have any food allergies or intolerances.

I gave birth to my daughter 10 weeks ago and my acne is starting to return just as it did with my son. Obviously I am devastated .
I was just wondering which hormones cause my acne to clear up during pregnancy and is there any way to emulate the actions of those hormones when I'm not pregnant?

I am breastfeeding and expect to continue so for the next couple of years.
Any help you can give me would be hugely appreciated.
