Pimples in early pregnancy: why it happens and what actually helps

7 min read

You expected a lot of changes when you found out you were pregnant. Breakouts, though, often catch women off guard. If your skin has suddenly decided to behave more like it did at fifteen than it did last month, you are not imagining it, and you are not alone.

Around 39% of pregnant women experience acne, most commonly in the first trimester.¹ Here is why it happens and, more usefully, what you can actually do about it.

Why pimples can show up in early pregnancy

Early pregnancy triggers major hormonal shifts. Those shifts can increase oil production and change how the skin behaves, which is one reason acne can appear or worsen during pregnancy.^2,3

Acne itself is not caused by "dirty skin". It develops when oil, dead skin cells and inflammation build up inside the pore. Hormonal changes can make that process easier.³

In practical terms, pimples in early pregnancy often look like:

• small clogged bumps across the forehead or chin
• inflamed pimples around the jawline, cheeks or mouth
• skin that feels both oily and sensitive at the same time

The first trimester tends to be the peak. For many women, skin settles in the second trimester as hormone levels stabilise. For others, breakouts continue throughout pregnancy.

Skincare ingredients that help with breakouts during pregnancy

Pregnancy skin can be more reactive, which means over-treating acne often backfires.⁴ The goal is not to strip the skin. It is to calm the breakout cycle without damaging the barrier. Many of the common ingredients for acne, including high-strength salicylic acid, benzoyl peroxide at high concentrations and retinoids, carry enough uncertainty during pregnancy to make alternatives the more considered choice. For a full breakdown of which ingredients are worth pausing and why, see our guide to skincare ingredients to avoid during pregnancy.

The good news is that well-studied alternatives exist for every step. Here is what the evidence supports for use during pregnancy:

Niacinamide

Niacinamide (Vitamin B3) is one of the most consistently recommended actives for breakout-prone skin during pregnancy. It reduces sebum production, supports the skin barrier, and has anti-inflammatory properties that calm the redness and swelling associated with active breakouts.⁵ It is well tolerated, has no reproductive hazard classification, and is appropriate for use throughout all trimesters.

Mandelic Acid

Mandelic Acid is a gentle alpha-hydroxy acid derived from bitter almonds. It exfoliates the skin surface, helping to prevent the dead cell buildup that contributes to congestion. Compared to other AHAs like glycolic acid, mandelic acid has a larger molecular size, which means it penetrates the skin more slowly and with less irritation, making it a considered option for skin that is both breakout-prone and sensitive.⁶ It is appropriate for use during pregnancy at standard cosmetic concentrations.

Gluconolactone

Gluconolactone is a polyhydroxy acid (PHA) that offers gentle exfoliation with additional antioxidant and barrier-supportive properties. It is one of the most well-tolerated exfoliating acids available and is suitable for use during pregnancy.⁶

Zinc

Topical zinc has documented anti-inflammatory and sebum-regulating properties. It is commonly found in mineral sunscreens and some targeted treatments, and is considered safe for use during pregnancy.⁷

Panthenol (Provitamin B5)

Panthenol supports barrier repair and reduces inflammation. In skin that is reacting to hormonal shifts, keeping the barrier intact helps prevent the cycle of irritation and breakout from compounding.

Ingredients to avoid when treating pimples during pregnancy

Two ingredients commonly used for acne are worth pausing during pregnancy:

Retinoids

Retinol, tretinoin and adapalene are effective for acne but are consistently recommended against during pregnancy by Australian dermatologists, given the well-established risks associated with oral retinoids and the limited evidence base for topical use.^8,9 Bakuchiol is the evidence-backed plant-derived alternative.

High-concentration salicylic acid

Low-dose salicylic acid in a daily cleanser is considered acceptable by MotherSafe, the clinical service at the Royal Hospital for Women in New South Wales.¹⁰ High-strength leave-on treatments and large-area application are better avoided. If you are using a salicylic acid product and are unsure whether the concentration is appropriate, speak with your GP or dermatologist.

A practical routine for breakout-prone skin during pregnancy

If your skin is breaking out, there is a strong temptation to throw everything at it. Usually, that makes it worse. The aim is to manage congestion and inflammation without disrupting the skin barrier or using ingredients with insufficient safety data. A considered routine does not need to be complicated:

• Cleanser: a gentle, low-foaming cleanser that removes excess sebum without stripping the barrier. Look for mandelic acid or gluconolactone if you want mild exfoliation built in.
• Treatment serum: niacinamide is the most versatile active for this stage, addressing both breakouts and the uneven tone that post-inflammatory pigmentation can leave behind.
• Moisturiser: even oily and breakout-prone skin needs hydration. A lightweight formula with ceramides and hyaluronic acid supports the barrier without adding congestion.
• SPF: daily mineral SPF 50+ is non-negotiable during pregnancy, particularly for breakout-prone skin, because post-inflammatory pigmentation (the dark marks left after a pimple) worsens significantly with UV exposure.

What about spot treatments?

Targeted spot treatments are trickier during pregnancy because many of the most effective options, including high-strength salicylic acid, benzoyl peroxide and retinoids, are best avoided or used with caution. A niacinamide-rich serum applied consistently over the affected area is a reasonable approach. Some women find that a small amount of zinc-based mineral sunscreen applied to a spot overnight also helps reduce inflammation, given zinc's established anti-inflammatory properties.

If breakouts are severe or causing significant distress, speak with a dermatologist. Prescription options that are considered appropriate during pregnancy do exist, and you do not have to simply wait it out.

A note on fragrance and essential oils

Pregnancy often brings a heightened awareness of what goes on your skin, which is a reasonable instinct. What is worth knowing is that fragrance and essential oils are among the most common causes of contact irritation in skincare, particularly when the skin barrier is already compromised by hormonal shifts.¹¹ A product being plant-derived or fragrance-forward does not make it better suited to reactive skin. If your skin is breaking out and feeling sensitive, fragrance-free formulas are the more considered choice.

A word on skin confidence

Breakouts during pregnancy can be emotionally difficult, particularly if your skin was previously clear or if you are navigating the vulnerability of early pregnancy alongside visible skin changes. That experience is worth acknowledging.

What is also worth knowing is that for most women, the skin settles. Hormonal acne driven by first-trimester hCG and progesterone surges tends to ease as levels stabilise. The changes are real, they are temporary, and they are manageable with the right approach.
