What should you know about Shereene Idriss melasma?

Melasma commonly appears on the cheeks, forehead, upper lip, nose or jawline. It can be associated with hormonal changes, family tendency, visible light and ultraviolet exposure. The colour may deepen after sun exposure and can return after improvement. Melasma is different from a sudden rash or a single changing mole, so appearance and history guide assessment.

Daily broad-spectrum sun protection, shade, hats and reapplication help limit pigment stimulation. A clinician may discuss a tailored brightening routine, prescription medicines or procedures such as chemical peels, microneedling or laser toning. Start one change at a time because irritation can make facial pigmentation look darker. Explore [Melasma](/conditions/melasma/) and [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/) for related information.

Arrange a dermatology assessment when patches are new, one-sided, rapidly changing, itchy, bleeding or unlike your usual pigmentation. Seek advice before using strong lightening products during pregnancy, breastfeeding or while taking medicines that affect skin sensitivity. A clinician can distinguish melasma from other causes of [Dark Patches On Skin](/symptoms/dark-patches-on-skin/).

Ask which pattern of pigmentation is present, whether your current products could be irritating your skin, which sunscreen features matter for your routine, and how long to try a treatment before reviewing it. Ask what warning signs should prompt an earlier appointment.
