Acne in Pregnancy and Gender: Complete Guide

"Bad skin means you're having a girl" is one of the oldest pregnancy gender myths around — the idea being that a daughter "steals" her mother's glow. It's a fun old wives' tale to swap with friends and family, but it isn't a reliable way to predict your baby's sex. Here's what's actually behind pregnancy acne, and why it has nothing to do with gender.

Where the "acne means girl" myth comes from

This tale sits alongside dozens of similar folk beliefs — carrying high or low, cravings for sweet or savoury food, and the shape of your bump — that have been passed down for generations. Like most old wives' tales about gender, it's essentially a coin flip: broadly around 50% accurate, which is no better than guessing. It can be a fun talking point at a baby shower or with family, but it shouldn't be treated as any kind of real prediction, and it certainly isn't a substitute for a scan.

What actually causes pregnancy acne

Breakouts in pregnancy are driven by hormones, not by the sex of the baby:

  • Rising progesterone and other hormones increase oil (sebum) production in the skin
  • This extra oil can block pores, leading to spots, particularly on the face, chest, and back
  • Acne tends to be most noticeable in the first and early second trimester, when hormone levels are shifting fastest
  • Some women who never had acne as teenagers develop it for the first time in pregnancy, while others with a history of acne may find it improves or worsens — this varies hugely from person to person
  • Increased blood flow and skin sensitivity can also make existing skin conditions feel more pronounced

Because these hormonal shifts happen in every pregnancy, regardless of whether you're expecting a boy or a girl, there's no biological mechanism linking skin changes to sex.

Managing pregnancy acne safely

If breakouts are bothering you, gentle skincare is usually the best starting point:

  • Wash your face twice daily with a mild, fragrance-free cleanser
  • Avoid picking or squeezing spots, which can lead to scarring
  • Check with your pharmacist, GP, or midwife before using any acne treatment, as some active ingredients commonly found in stronger skincare products aren't recommended in pregnancy
  • Look for pregnancy-safe options recommended by a pharmacist if over-the-counter products don't help
  • Be patient — for many women, skin settles down again after the hormonal surges of early pregnancy pass

Frequently Asked Questions

Does having acne in pregnancy really mean I'm having a girl?

No. Pregnancy acne is caused by hormonal changes that occur in every pregnancy, whether you're carrying a boy or a girl. Like other gender-prediction folklore, it's roughly 50% accurate — the same as a coin toss — so it's fun to guess with, but not something to rely on.

Is it normal to get acne for the first time during pregnancy?

Yes, it's very common. Hormonal shifts, particularly increased oil production, can trigger breakouts even in women who have never had acne-prone skin before. It usually eases as hormone levels stabilise later in pregnancy or after birth.

What's the only reliable way to find out my baby's sex?

The most accurate methods are a mid-pregnancy anomaly scan (usually around 18–21 weeks on the NHS) or specific blood or genetic tests offered in certain circumstances. Nub theory, based on ultrasound images around 12–13 weeks, can offer an earlier informal indication when interpreted by someone experienced, but it is not diagnostic and should never replace a formal scan.
