What to know about a growing dark spot on skin

Melasma often forms broader, fairly even patches on sun-exposed areas. Post-Inflammatory Hyperpigmentation can follow acne, eczema, burns, or an injury. Sun Spots are usually discrete areas of pigment after cumulative sun exposure, while Tinea Versicolor can create lighter or darker patches with fine scale. These conditions can overlap in appearance, so location, texture, symptoms, and timing matter.

Photograph the spot in consistent lighting and note changes in size, edge, colour, itch, bleeding, or scale. Use broad-spectrum sun protection and avoid picking or applying harsh bleaching mixtures. Once the cause is clear, a clinician may discuss Chemical Peel, Skin Brightening Treatment, or Picosecond Laser Treatment; these are not appropriate for every pigment change and can irritate sensitive skin.

Arrange prompt dermatology review if the spot changes quickly, develops an uneven edge or several colours, bleeds, crusts, becomes painful, or differs clearly from your other marks. New pigment on the palms, soles, nails, or mucosal skin also deserves assessment. Do not delay review while trying a cosmetic product.

Ask what features support the diagnosis, whether the spot needs dermoscopy or a sample, what may be driving the pigment, and how long improvement could take. Ask how to reduce irritation and how recurrence will be monitored.
