Melasma appearing during pregnancy is common and is driven by hormonal changes together with sun and heat exposure. It often fades in the months after birth, though not always. The one intervention that helps regardless of which actives you are avoiding is rigorous, reapplied sun protection.

Why it happens now

Hormonal shifts during pregnancy increase pigment-producing activity, and sun exposure then triggers where that pigment lands. The symmetrical, map-like pattern across cheeks, forehead and upper lip is characteristic. It is sometimes called the mask of pregnancy.

Sun protection is the whole strategy

With many brightening actives paused, sun protection stops being one tool among several and becomes the main one. Broad-spectrum SPF applied generously and reapplied, plus a hat and shade at midday. Visible light aggravates melasma as well as UV, which is why tinted sunscreens containing iron oxides are usually suggested for it specifically. Heat alone can aggravate it too, so hot showers and saunas are worth moderating.

What to expect afterwards

Pregnancy melasma frequently fades over the months following birth as hormones settle. Some of it persists, and that is when a dermatologist becomes worth seeing — melasma is genuinely difficult and responds far better to a planned medical approach than to a rotating cast of serums.

What not to do

Do not attempt aggressive at-home treatment while pregnant, and do not scrub. Irritation makes melasma worse, reliably. Hold the line with sunscreen and revisit actives with your doctor afterwards.
