Melasma is a pigmentation condition causing symmetrical brown or grey brown patches, usually on the cheeks, forehead and upper lip. It is driven by UV exposure, hormones and genetics, and is more common in women, often appearing during pregnancy or with hormonal contraception.
Management starts with strict daily sun protection, since sunlight reverses progress quickly. Prescription fading creams and other combination approaches can lighten patches over months. A telehealth skin review with photos allows assessment and a maintenance plan suited to Australian UV conditions.
