Dark spots on the feet

Foot pigment can darken after a blister, cut, insect bite, eczema flare, shoe rubbing, or repeated pressure. A flat brown mark differs from a thick callus, a scaly patch, or a spot beneath a nail. Moisture between the toes can also support fungal skin changes, while pigment conditions such as Tinea Versicolor may cause lighter or darker areas elsewhere.

Note whether the mark is on the sole, top of the foot, toe, or nail; whether it is single or multiple; and whether it is growing, itchy, scaly, tender, or bleeding. Photos taken in consistent light can help a clinician compare change.

Keep feet clean and dry, change damp socks, choose shoes that do not rub, and avoid picking at peeling skin. Do not use strong acids or unlabelled lightening creams on broken skin. If there is scale or itch, have the cause checked rather than treating pigment alone.

Once the skin is healthy, a clinician can discuss options for persistent pigment. Depending on the diagnosis and location, these may include Skin Brightening Treatment, a Chemical Peel, or Picosecond Laser Treatment. Foot skin and nails need individual assessment because irritation can worsen discolouration.

Book a prompt assessment for a new or changing dark spot, especially one with an irregular border, multiple colours, bleeding, crusting, or persistent pain. Seek care sooner if redness, warmth, swelling, pus, fever, or a wound that does not heal accompanies the pigment. People with reduced foot sensation or circulation should have persistent marks checked early.

Ask whether the spot is pigment, a callus, infection, or a nail change; whether testing is needed; and which foot-care products are safe for the affected surface.
