Low Dose Birth Control Pills Control Acne But Can They CAUSE It Too?
Is my brand of low dose birth control pill causing my acne? I have been asked this several times so here is an oversimplified answer and explanation which I hope will shed light on this issue and help those of you for whom this is a real problem.
All birth control pills are not equal even though 98% of pills prescribed today are low dose ones. As you know, there are low dose birth control pills that contain a combination of 2 types of synthetic hormones, estrogen and progestin and pills that contain only PROGESTIN (often called the mini pill)
The synthetic estrogen in all birth control pills is of the same type (ethinyl estradiol) so it’s easy to compare doses across brands of BC pills. UPDATE to this post 2011 On May 6, 2010 the Food and Drug Administration approved Natazia as the first ever birth control pill to use estradiol valerate in the United States.
The TYPE and strength (potency) of synthetic progestin varies across brands of birth control pills.
There are 8 types of progestin which vary in strength so 2 diffent brands of pill can appear to contain the same dosage of progestin but if they contain different TYPES of progestin, the strength of the dose will vary and so may the effect it has on your body. Stay with me here because this is where acne enters the picture.
Progestin in a birth control pill helps to prevent ovulation but it can also increase ‘androgenic activity’ which in turn can encourage the devlopment of acne and other side effects reflective of male characteristics.
What is androgenic activity?
Androgenic ( ‘andros’ meaning man + genein meaning to produce). Androgenic activity begins in puberty, when androgen (male hormone) is produced by the testes (between 12 and 14 yrs in men) and the adrenal glands. Both men and women produce androgens and androgenic activity can be higher in some women than others, resulting in side effects such as excessive body hair and other male characteristics, including acne.
So depending on the type of progestin in my birth control pill, my acne could get worse? This is a possibility if your adrenal glands are producing a higher than normal level of androgen. Combine this tendency with a low dose birth control pill high in androgenicity and you can see the consideration needed as to which brand of birth control pill will suit you best. If your low dose birth control pill is one that contains a type of progestin with high androgenic activity and a low estrogen content you may wish to ask your doctor about switching to a pill with a lower androgenic activity and a higher estrogen content. I bet that will impress! Talk to a health care professional if you think your type of acne is hormonal, since a change of birth control pill may only be part of a combined treatment type of treatment for you. You may be prescribed anti -androgen drugs to reduce oil production so it’s vital that if you also prefer to use oral contraceptives as your birth control that you let your doctor ‘mix the cocktail’ for you. Examples of pills that may make your acne worse would be those at the bottom of the list below but I stress that these brands DO NOT cause acne in women with normal levels of androgen.
Low dose birth control pills with a low androgenic activity and a higher doses of estrogen help to reduce the side effects related to androgenic activity. What the effect may be on blood clots, we have yet to discover. It is swings and roundabouts and the merry - go -round of trialing low dose birth control pills can be a test of endurance.
Yaz/Yasmin
Low dose birth control pills such as Yaz/Yasmin contain a unique type of progestin (drospirenone) to all the others and also has low androgenic activity in the body which probably accounts for this brand’s popularity and success with many acne sufferers.

Be aware that if you also have an issue with weight gain or suffer from other medical conditions such as endometriosis for instance, this will most likely have been taken into consideration when your doctor prescribed the type of progestin that would be most suitable for you. I hope that understanding the link between progestins, androgen activity and acne will help you to manage your low dose birth control much better. Hormonal birth control does not have to be part of everyone’s contraceptive career, however, so don’t be afraid to explore something different, ask lots of questions and be optimistic about finding the right solution for YOU. Hormones are not to messed with so a DIY approach to treating your acne just by changing your low dose birth control is not a good idea- talk to your doctor.
