Melasma in pregnancy: what does it mean?

Pregnancy-related melasma is sometimes called a pregnancy mask. It usually appears as flat, uneven brown or grey-brown areas on the face, though pigment can vary between people. Sun and visible light may make it more noticeable. It is a skin change rather than a sign that the pregnancy is unhealthy, but another rash or changing lesion should not be labelled melasma without a check. Pregnancy hormones can also make skin more reactive, so irritation may deepen colour.

Protect exposed skin with shade, clothing, and a pregnancy-appropriate sunscreen recommended by your clinician. Use a bland cleanser and moisturiser, and stop products that sting, peel, or cause redness. Discuss every medicated lightening cream with your obstetric or dermatology team before use. Cosmetic procedures such as chemical peels, microneedling, or laser toning are generally decisions for after pregnancy unless a qualified clinician specifically advises otherwise. Do not scrub the patches.

Ask for an assessment if pigmentation is itchy, painful, scaly, blistered, rapidly changing, or confined to an unusual single spot. Seek prompt care for a bleeding or non-healing area. A clinician can distinguish melasma from pregnancy-related rashes and advise on products that fit your stage of pregnancy.

Does this pattern fit melasma? Which sunscreen and skincare ingredients are suitable now? Should I pause my current treatment? When would it be reasonable to consider procedures after pregnancy?
