What should you know about dark spots on hands?

Flat brown or grey marks may be sun spots or post-inflammatory hyperpigmentation left after a cut, rash, burn, or insect bite. Melasma can cause patchy facial pigment but is less typical on the hands. Tinea versicolor more often causes fine-scaled patches on the trunk, although a clinician can help distinguish it from other pigment changes.

Notice whether each mark is flat or raised, smooth or scaly, evenly coloured or mixed in colour. A photograph in natural light can help you track change without repeatedly rubbing the area.

Apply broad-spectrum sunscreen to the backs of your hands and reapply after washing or outdoor activity. Use gloves for repeated contact with detergents, solvents, or rough materials, and moisturise after handwashing. Avoid picking, bleaching mixtures, or unprescribed lightening creams, which can irritate skin and deepen pigment.

If marks persist or bother you, a dermatologist can identify the pigment pattern before discussing options such as a chemical peel, skin brightening treatment, or picosecond laser treatment. The choice depends on depth, cause, skin tone, and the risk of irritation.

Arrange a prompt skin review for a spot that is new and continues to change, becomes asymmetric, develops an irregular edge, gains several colours, bleeds, crusts, hurts, or fails to heal. Seek earlier advice if many marks appear quickly or if pigment follows a new medicine or widespread rash.

Ask whether the marks fit sun spots or post-inflammatory hyperpigmentation, whether a dermatoscope examination is needed, and which products are suitable for your skin tone. Ask how long to try a plan, what irritation looks like, and how to protect the hands during treatment.
