What should you know about butterfly melasma?

Melasma develops when pigment-producing cells make extra melanin. The colour can look tan, brown, or grey-brown and may deepen after sunlight, visible light, heat, or hormonal changes. It is usually flat rather than raised, and it does not behave like an infection. Similar-looking dark patches can have other causes, so an examination is useful when the diagnosis is uncertain.

Use broad-spectrum sunscreen every morning, add a hat or shade outdoors, and reapply during prolonged exposure. Choose gentle, fragrance-free skincare and avoid scrubbing or picking, because irritation can make pigmentation more noticeable. A dermatologist may discuss prescription lightening treatment or procedures such as Chemical Peel, Microneedling, Skin Brightening Treatment, or Laser Toning; suitability depends on skin tone, sensitivity, pregnancy status, and the depth of pigment.

Arrange a skin assessment if patches are new, changing quickly, itchy, painful, scaly, bleeding, or confined to one unusual spot. Seek prompt care for facial swelling, blistering, eye involvement, or a widespread reaction after a product or medicine. Persistent facial darkening also merits review because treatment works best after the cause is confirmed.

Could this be melasma rather than another cause of dark patches? Which sunscreen and pigment treatment fit my skin? Would a peel, microneedling, or laser increase irritation or recurrence? How should treatment change if I am pregnant or planning pregnancy?
