Melasma in Pregnancy: How to Prevent the “Mask of Pregnancy”

By DermLens AI · 11 October 2026 · 6 min read

Dark patches on the cheeks, forehead and upper lip during pregnancy are called melasma, sometimes nicknamed the “mask of pregnancy”. It is harmless medically, but it can be distressing, and a 2024 review points out that for some women it does not fade after the baby arrives. The good news is that prevention is possible, and it is mostly about sunscreen.

How common is it?

A 2024 review of melasma prevention in pregnancy reports prevalence during pregnancy of 36.4% to 75%. It also reports that up to 30% of cases persist after delivery, even ten years later, and that recurrence and aggravation are common in subsequent pregnancies. That is why prevention is worth the effort.

The core strategy: photoprotection from the first trimester

The same review emphasises the critical role of photoprotection, including using sunscreen from the first trimester, in reducing how often melasma develops. A 2025 review of photoprotection in pregnancy adds that pregnancy changes how skin responds to UV light and raises the risk of pigmentary disorders such as melasma and linea nigra, and that sunscreen use among pregnant women is generally low despite the evidence for its benefits.

Which sunscreen?

According to the 2025 review, sunscreen for pregnancy should ideally be:

• Mineral-based, potentially supplemented with safe organic filters so it feels pleasant enough to use every day
• Free from ingredients associated with potential risks during pregnancy
• Tinted, where possible. Tinted sunscreens protect against high-energy visible light, which may help prevent hyperpigmentation, and give some camouflage. The review notes that shade ranges should match diverse skin tones.

It recommends a broad strategy: wide-brimmed hats, sun-safe clothing and regular use of high-SPF, broad-spectrum sunscreen that protects against UVB, UVA and high-energy visible light.

Making it a habit

• Every morning, as a daily habit rather than only on sunny days.
• Apply generously and reapply if you are outdoors for long. See understanding SPF for how much to use.
• Pick a texture you enjoy. The best sunscreen is the one you actually wear.

What about treating melasma during pregnancy?

Prevention is the focus of this article. Several common pigmentation treatments are not recommended in pregnancy. Our pregnancy skincare guide explains why hydroquinone is on the avoid list, and what you can use instead. Speak to your midwife, GP or a dermatologist before starting any treatment.

The bottom line

Melasma is common in pregnancy and can last. The best-supported prevention is daily, broad-spectrum sunscreen from the first trimester, ideally mineral and tinted, with hats and clothing as back-up.
