Mild pitted keratolysis treatment: what to know

This superficial bacterial infection affects the pressure-bearing skin of the soles. Small shallow pits or tiny crater-like depressions can appear, often with a strong foot smell. It may be more noticeable after wearing closed shoes, sweating, or spending long periods in damp socks. The appearance can overlap with other causes of scaling or odour, so a clinician may examine the skin before choosing treatment.

The condition is not a sign that you are unclean. Moisture softens the outer skin and creates an environment where bacteria can multiply. Odour can continue while the feet remain warm and damp; see our guide to Body Odour for related symptom information.

Wash the feet gently, dry carefully between the toes, and change socks when they become damp. Rotate shoes so they can air out, and choose breathable footwear when practical. Avoid harsh scrubbing or picking at the pits, which can irritate the surface.

A clinician may recommend a topical antibiotic such as Topical Antibiotic Therapy. If sweating is a major trigger, Prescription Antiperspirant may be discussed. Use each product only as directed, and allow time for the skin to recover after treatment begins.

Arrange a medical review if the pits spread, the skin becomes painful, red, swollen, cracked, or drains fluid, or the smell persists despite careful drying. Prompt assessment is sensible for fever, rapidly worsening tenderness, or difficulty walking. A clinician can check whether another infection or a deeper problem needs different care.

Ask whether the pits and odour fit pitted keratolysis, how long to use the recommended product, and whether sweating or footwear is contributing. You can also ask how to clean shoes safely and what changes should prompt a follow-up visit.
