Fill the basin with warm (comfortable) water that covers your feet up to ankles.
Add optional Epsom salt (1–2 tbsp) or vinegar (≈ ½ cup vinegar per liter/basin) to help soften the thick skin.
Soak your feet for about 10–20 minutes. This softens the tough skin and makes later steps safer and more effective.
Pat feet dry gently (especially between toes) — don’t leave them soggy.
Step 2: Exfoliate gently the thickened skin
While the skin is still slightly damp (but not soaking), take the pumice stone or foot file.
Gently rub the thickened areas (heels, balls of feet, sides) in circular or side-to-side motions. Do not try to remove all the thick skin in one go. Removing too much or using sharp tools can cause injury.
Focus on smoothing the rough part, not completely eliminating the skin layer (since callused skin has some protective function).
Rinse off any debris and pat dry.
Step 3: Apply moisturiser and seal it in
