What should you know about brachial melasma?

Melasma is usually flat and patchy rather than raised, with colour ranging from light brown to grey-brown. On the arms, exposed skin may darken more visibly after sun or heat, while friction or a previous rash can add post-inflammatory pigment. Compare both arms and note whether the patches are symmetric, slowly changing, itchy, scaly, or tender. Dark Patches On Skin and Uneven Skin Tone describe related visible concerns, but a clinical examination is needed when the pattern is atypical.

Use broad-spectrum sunscreen on exposed arms, cover the area when practical, and avoid picking or irritating products. A gentle cleanser and moisturiser support the skin barrier. A dermatologist may discuss Skin Brightening Treatment, Chemical Peel, Microneedling, or Laser Toning after confirming the diagnosis. Sun-Damaged Skin can add to uneven pigment, so daily protection matters even when a procedure is planned.

Book an assessment if pigment appears suddenly, changes quickly, becomes raised, bleeds, crusts, or is persistently itchy or painful. Seek prompt care for swelling, blistering, or a rapidly spreading inflamed area. Review medicines, hormones, recent rashes, and sun or heat exposure with the clinician because these details can change the diagnosis and treatment plan.

Does this look like melasma or pigment left after inflammation? Could a medicine, hormone change, or sun exposure be contributing? Which treatment is appropriate for my skin tone, and how will you reduce the chance of irritation-related darkening?
