What should you know about raised dark spots on skin?

A flat brown area that remains after a rash, bite, acne spot, or injury may be post-inflammatory hyperpigmentation. Symmetrical facial patches can occur with melasma, while long-standing sun-exposed spots may be sun spots. Fine scaling with lighter or darker patches can point toward tinea versicolor. A spot that is genuinely raised may instead be a mole, wart, seborrhoeic keratosis, or another lesion; colour alone cannot identify it.

Notice whether the surface is scaly, rough, smooth, crusted, or bleeding. Record its location and whether it is enlarging, changing colour, multiplying, or becoming tender or itchy. A photograph beside a ruler can help show change without trying to diagnose the spot at home.

Use broad-spectrum sun protection on exposed skin, avoid picking or scrubbing, and stop any product that burns or causes a new rash. Do not apply bleaching mixtures or strong acids without professional guidance. A clinician can examine the surface and decide whether treatment such as a chemical peel, skin brightening treatment, or picosecond laser treatment is appropriate; these options depend on the cause and skin type.

Arrange a dermatology review for a new or changing raised dark spot, especially if it develops uneven colour, an irregular outline, repeated crusting, bleeding, or a sore that does not heal. Seek prompt care for rapid change, marked pain, pus, or spreading redness. These warning signs do not establish a diagnosis, but they make an examination more useful and timely.

Ask whether the lesion is mainly pigment or a raised growth, whether a dermatoscope examination is needed, and which warning changes should prompt follow-up. Discuss safe options for your skin tone and whether testing is needed before a cosmetic treatment.
