Acne during pregnancy

Contrary to popular belief, acne is not a condition that only affects teenagers and is solely linked to puberty. It can also occur during pregnancy. The cause lies in hormonal changes in the pregnant woman’s body. But how should it be treated—and is it true that acne could be a sign of having a girl?

Causes of acne during pregnancy

During pregnancy, levels of progesterone and androgens in a woman’s body rise. This stimulates the sebaceous glands and increases sebum production. If the gland ducts become clogged, bacteria can multiply—leading to the development of acne. It typically appears on the face and back and is most common during the first trimester of pregnancy. Greasy hair is also frequently associated with this condition. In the second and third trimesters, many women notice a significant improvement in their skin, which may be due to the effects of estrogen.

Stress and an unbalanced diet can also negatively impact skin health. Chocolate and spicy foods should be avoided to reduce the risk of unwanted skin blemishes—though specific cravings are common during pregnancy.

Unfortunately, acne can persist even after birth and may continue during breastfeeding. This is linked to increased levels of the hormone prolactin, which not only regulates milk production but also supports the growth of breast tissue.

How to treat acne during pregnancy

Treating acne during pregnancy is challenging, as many medications are not suitable for pregnant women. Acne treatments based on vitamin A derivatives (retinoids) are teratogenic for the developing fetus and can cause serious developmental disorders. They also pass into breast milk and are therefore contraindicated during breastfeeding as well.

Pregnant women should also not be prescribed antibiotics like tetracyclines, which are otherwise commonly used to treat acne.

This makes appropriate skincare especially important: using suitable creams and thoroughly cleansing the face to prevent makeup residues from clogging pores and contributing to breakouts.

Taking any medication—even herbal or homemade remedies—should always be discussed with a gynecologist or dermatologist to avoid side effects such as unwanted pigmentation changes.

If undergoing cosmetic treatments, the beautician should be informed of the pregnancy. Procedures like chemical peels or ultrasound facials should be postponed until after childbirth.

Acne during pregnancy – Boy or Girl?

According to a widespread myth, skin problems and changes in hair and nails are signs of carrying a girl—because “a girl steals the mother’s beauty.” While there is no scientific basis for this belief, many people continue to hold onto it. Ultimately, it remains a superstition—the baby’s gender should be determined via ultrasound by a gynecologist.

Other skin issues during pregnancy

One very common skin issue during pregnancy is the so-called pregnancy mask (chloasma or melasma). These are pigment spots on the face, usually on the nose, cheeks, and forehead. Sun exposure can intensify this pigmentation, which typically begins around the 16th week of pregnancy.

These discolorations are caused by increased melanin deposits. In addition to the face, they also occur around the nipples and anal area. They cannot be prevented.

Another symptom, often considered bothersome, is the so-called linea nigra—a dark line that runs from the belly button to the pubic bone.
