Palmar hyperpigmentation: what to know

Colour can deepen after inflammation, repeated rubbing, contact with an irritant, or healing skin injury. It may be even or patchy, and can occur with dryness, scale, itch, or tenderness. Ask whether the change affects both palms, the creases, fingertips, nails, mouth, or other body areas. A new medicine, occupational exposure, or a general symptom such as fatigue or appetite change can be relevant. Appearance alone cannot identify the cause, and a dark patch should not be treated as a cosmetic issue until a clinician has considered the pattern.

Use a gentle cleanser, moisturise regularly, and reduce friction or exposure to products that sting. Photograph the palms in similar lighting and list new medicines, supplements, gloves, detergents, and skin treatments. Do not scrub, use lemon or bleaching mixtures, or start hydroquinone without professional guidance; irritation can deepen post-inflammatory colour. Once the cause is understood, a clinician may discuss options such as topical treatment, a chemical peel, IPL Photofacial, or Picosecond Laser Treatment, depending on the skin and diagnosis. Sun protection for exposed hands can help limit further darkening.

Arrange an assessment for new, spreading, rapidly changing, painful, itchy, scaly, bleeding, or unevenly coloured patches. Seek prompt care if darkening comes with marked fatigue, dizziness, faintness, vomiting, unexplained weight change, or changes in the mouth or nails. Urgent care is appropriate for a severe reaction with facial swelling or breathing difficulty. A dermatologist can decide whether examination, medication review, or testing is needed before cosmetic treatment.

Does the distribution suggest irritation, post-inflammatory colour, medication effect, or a broader health issue? Should I stop any product or medicine, and what examination is needed? Which treatment is appropriate for my skin tone and cause, and how can irritation after treatment be reduced?
