What should you know about feet hyperpigmentation?

Darkening may follow rubbing from footwear, healed bites, eczema, a rash, or repeated inflammation. It can be flat or slightly thickened, and may affect the toes, top of the foot, sole, or ankles. The pattern, texture, speed of change, and any itch or pain help guide evaluation. Dark patches on skin can have several causes, so colour alone cannot identify the reason. A clinician may review new products, shoes, sun exposure, medicines, and previous injuries before recommending treatment.

Reduce rubbing with well-fitting shoes and soft socks. Use a gentle cleanser, moisturise dry areas, and avoid scratching or harsh scrubs. Do not apply bleaching mixtures or strong acids without medical advice; irritation can deepen pigmentation. Take a clear photograph in consistent light so changes are easier to track. After the cause is addressed, a clinician may consider Skin Brightening Treatment, Chemical Peel, IPL Photofacial, Picosecond Laser Treatment, or Hydroquinone Treatment, depending on skin type and the diagnosis.

Book an assessment for a patch that is new, enlarging, uneven in colour, bleeding, crusting, persistently painful, or different from other marks. Seek prompt care if darkening appears with marked swelling, warmth, ulcers, or a wound that is not healing. Rapid change should be examined rather than treated at home.

What is the likely cause of this colour change? Could irritation or inflammation be continuing? Which treatment is appropriate for my skin tone, and what side effects or preparation should I expect?
