Does Pregnancy Cause Acne?

Pregnancy Usually Helps Clear the Skin, But Sometimes It Can Worsen Acne, Especially During the Third Trimester

Does Pregnancy Cause Acne?

Article Summary

Pregnancy normally helps clear up acne. Pregnancy causes increased estrogen levels, which can provide protection against acne. However, especially during the third trimester, pregnancy can also come with increased androgen (male hormones that are present in both males and females) levels and increased skin oil production, which can sometimes trigger acne. If acne does flare during pregnancy, the choice of treatment depends upon how severe the flare is.

Important Note: Acne treatment during pregnancy should always be supervised by a doctor.

The hormonal changes that pregnancy causes in the body normally help provide a reprieve from acne, but in some instances can cause a flare of acne.  

Why does acne normally lessen during pregnancy? Levels of estrogens (female hormones that are present in both males and females) increase throughout pregnancy. In general, higher estrogen levels protect against acne.1,2

However, this is not always the case. Androgen (male hormones that are present in both males and females) levels can also sometimes increase during pregnancy, particularly during the third trimester. This can cause skin oil glands to become more active, resulting in the production of more skin oil, which may cause a flare of acne. Because skin oil glands produce more oil during late stages of pregnancy, some women experience not only acne, but also greasy skin, especially on the face.1,3-5

How Pregnancy Can Affect Acne
In the following chart you can see how estrogen levels increase throughout pregnancy (see the red line). Increased estrogen levels may help protect against acne, and is likely why most women see their acne subside during all trimesters of pregnancy.

Acne During Pregnancy

Most of the evidence in the scientific literature shows that acne improves during pregnancy, however, some studies show that it can worsen in some women.6-9

As these studies indicate, while some women do experience acne flares during pregnancy, the overall trend is toward improvement of acne during pregnancy.

Treating Acne During Pregnancy 

If acne does flare during pregnancy, treatment depends on the severity of the acne. It is very important for any pregnant woman to ask her doctor before embarking on a medicated regimen.

Topical treatments. For mild acne, a topical (applied to the skin) treatment may help. Topical treatments include:

Oral antibiotics. For severe acne flares, oral antibiotics that are safe to use during pregnancy, such as erythromycin and penicillin, may provide relief. However, many common oral antibiotics are not safe during pregnancy, and even the oral antibiotics that are deemed safe can only be used for short periods of time and often do not provide adequate results. Oral antibiotics also have undesirable side effects such as diarrhea, and they contribute to antibiotic resistance, in which bacteria become resistant to antibiotics and the antibiotics lose their effectiveness against these bacteria.

Light therapy. Light therapy is an alternative treatment that some physicians advise during pregnancy. However, UVB light treatment can reduce the levels of folic acid in the body. Because adequate amounts of folic acid are essential during pregnancy, any woman undergoing UVB therapy during pregnancy should have her blood levels of folic acid tested and should take folic acid supplements if necessary. However, women should never take folic acid supplements without consulting their doctor, because too much folic acid is toxic.

Other alternatives. Other alternative treatments, such as tools called comedone extractors that remove the material from clogged pores, and microdermabrasion (using a device to abrade away the outer layers of the skin), are safe to use during pregnancy. However, while both of these treatments might improve the appearance of skin in the short term, they do nothing to treat acne. They also both physically irritate the skin, which can bite back with breakouts in the weeks following.5

CAUTION: Oral retinoid medications, such as Accutane (isotretinoin), cause harm to the fetus and therefore should never be used during pregnancy or when trying to conceive.10 Doctors are also cautious about prescribing topical retinoids and other prescription medications during pregnancy. Be sure to speak with your doctor before using any medication while pregnant or planning to become pregnant.
