Does melasma cause dark patches on skin?

Melasma often creates flat brown, grey-brown, or darker patches with fairly clear but irregular edges. They commonly appear on the cheeks, forehead, nose, upper lip, or jaw, and may occur on both sides of the face. Sunlight and visible light can deepen the pigment, while heat, hormonal changes, and irritation may influence activity. The patches are usually not scaly or painful, so a new textured, tender, or bleeding mark may have another cause.

Use broad-spectrum sun protection every day and add shade, a hat, or other physical protection outdoors. Choose gentle, fragrance-free skincare and stop products that sting or inflame the area. A dermatologist can confirm the diagnosis and discuss topical treatment or procedures suited to your skin. Improvement is gradual, and pigment can return when triggers continue, so follow-up helps adjust the plan.

Arrange an assessment for new dark patches, pigment that changes quickly, or an uncertain diagnosis. Seek prompt review if a patch becomes raised, scaly, painful, crusted, or bleeds, because those features are not typical of uncomplicated melasma. An appointment is also useful when pigmentation affects your wellbeing or does not respond to a gentle routine.

Ask whether the pattern fits melasma, which light and heat triggers matter for you, and which sunscreen and treatment options suit your skin. Ask how to introduce products safely and what irritation or colour change should prompt a review.
