Dark patches can arise for different reasons, including melasma and marks left after inflammation. Identifying the cause matters because the same treatment is not suitable for every type of pigmentation.
Dark patches on the skin can have several causes, including melasma and marks left after inflammation. The right treatment depends on identifying what caused the pigmentation; the same approach will not suit every patch.
Why do dark patches appear?
Melasma commonly appears as darker patches on sun-exposed skin and can be influenced by sunlight and hormonal factors. Other dark marks can follow irritation or acne. A clinician can examine the pattern and ask about timing, products and health history; not every dark patch is melasma.
What happens during assessment?
Discuss where the marks are, when they appeared, whether they have changed, treatments already tried and any pregnancy plans. A dermatologist can explain the likely diagnosis and whether further assessment is needed. A changing, bleeding or otherwise concerning skin lesion should be assessed promptly rather than treated as a cosmetic mark.
How is pigmentation managed?
Sun protection is an important part of care. A clinician may discuss skin-care changes or prescription treatments depending on the diagnosis and your circumstances. Irritating products or unsuitable procedures can worsen marks in some people. Ask about expected timelines, risks and maintenance, and avoid unverified products or combinations.
