Okay so I'm trying to be my own detective here and need some help from anyone who knows alot about acne formation.

Basically, I was completely clear during pregnancy and am trying to figure out why since it was the only time since my childhood I've had such nice skin.

So I did some research on how the body changes when pregnant and this is what I found:

Endocrine system (non-reproductive)

Pituitary

* FSH/LH fall to low levels.

* ACTH and melanocyte-stimulating hormone increase.

* Prolactin increases.

Thyroid and parathyroid1,2

* Thyroxine-binding globulin (TBG) concentrations rise due to increased oestrogen levels.

* T4 and T3 increase over first half of pregnancy but there is a normal to slightly decreased amount of free hormone due to increased TBG-binding.

* TSH production is stimulated, although in healthy individuals this is not usually significant. A large rise in TSH is likely to indicate iodine deficiency or subclinical hypothyroidism.

* Serum calcium levels decrease in pregnancy which stimulates an increase in parathyroid hormone (PTH).

* Colecalciferol (vitamin D3) is converted to its active metabolite, 1,25-dihydroxycolecalciferol, by placental 1α-hydroxylase.

Adrenal and pancreas3

* Cortisol levels increase in pregnancy, which favours lipogenesis and fat storage.

* Insulin response also increases so blood sugar should remain normal or low.

* Peripheral insulin resistance may also develop over the course of pregnancy and gestational diabetes is thought to reflect a pronounced insulin resistance of this sort.

Cardiovascular system4

* Progesterone reduces systemic vascular resistance by about 20% early in pregnancy. Postural hypotension may result.

* Diastolic and systolic blood pressure tend to fall during mid pregnancy and then return to normal by week 36.

* Venous return in the inferior vena cava can be compromised in late pregnancy if a woman lies flat on her back. This is relieved by lying in the left lateral position.

* Increased circulating angiotensin II encourages water and sodium retention leading to an increased plasma volume (to 50% by 30 weeks) and predisposing to oedema. This enables increased uterine blood flow to meet growing nutritional and oxygenation needs of the fetus. It also enables blood loss (average 500 ml) at delivery to be met without physiological decompensation.

* Advise women not to take up unaccustomed, vigorous exercise in pregnancy as there is a risk of diversion of uterine blood flow to the skeletal muscles.

* Blood flow to kidneys, skin and mucosa increases.

* Cardiac output increases by 30-50% with 15% increase in heart rate and 25-30% increased stroke volume. Much of this adjustment occurs prior to 12 weeks' gestation and so impaired cardiac function is likely to present problematically in early pregnancy or with the sudden increase in pre-load in the third stage of labour.

So I was just wondering if any of these things would coincide with acne improvement?

Thanks so much and feel free to move this if it's in the wrong place :)

Acne is caused by too much androgens (ie. testosterone). When you're pregnant, your estrogen is increased, and you have less androgens. That's probably why you cleared up.

Some women are quite the opposite and break out when pregnant from too much estrogen.

Everyone is different.

Thanks so much for your response!

So does that mean that something like a high dose estrogen birth control pill might be the answer. Or is there some type of herb I can use to increase estrogen?

The pill has helped many women. I'm not aware of an herb, but fish oil (omega 3 fatty acids) and evening primrose oil (omega 6) can help regulate hormones.

Definitely check out the nutrition/holistic section of the message board :)
