How to treat pitted keratolysis

Pitted keratolysis affects the outer skin of the foot. Bacteria thrive when sweat, heat, and enclosed shoes keep the surface wet; they can create small depressions and an unpleasant smell. The pattern often affects the soles, particularly areas that bear pressure. Itching may be absent, so a lack of itch does not rule it out.

A healthcare professional can distinguish it from fungal infection, eczema, warts, or other causes of altered skin. That distinction matters because the treatments are different and combining products without advice can irritate the skin.

Use the prescribed topical treatment as directed. Wash gently, dry every part of the foot including between the toes, and change socks whenever they become damp. Alternate shoes so each pair can dry fully; breathable materials may help. Avoid picking at pits or scrubbing hard, which can damage the surface and make it easier for irritation to continue.

If sweating is a major trigger, ask about [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/). [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) may be explained as part of the treatment discussion. Persistent odour can also be read about under [Body Odour](/symptoms/body-odour/).

Seek prompt assessment for increasing pain, warmth, swelling, open cracks, drainage, spreading redness, or fever. Make an appointment when self-care is not helping, the pits keep returning, or the diagnosis is unclear. People with diabetes, reduced sensation, or poor circulation should arrange foot changes for review rather than treating them on their own.

What confirms pitted keratolysis in my case? Which topical treatment is suitable, and when should improvement begin? Could sweating, footwear, or another skin condition be maintaining the problem?
