What tools can be used to remove heel calluses?

When removing heel calluses, choose the right tool based on callus thickness, skin sensitivity and usage scenario to avoid damage from excessive pruning. Here are the commonly used tools and usage recommendations by function:
1.Physical Abrasives (suitable for Mild/Moderate Calluses)
Pumice Stone
How it works: The porous structure of natural volcanic rock removes dead skin through friction.
Best for: Use after a shower on damp skin. Suitable for large and thin calluses such as heels and soles.
Pros: Affordable, chemical-free and reusable.
Weaknesses: Needs regular cleaning to prevent bacterial growth and is less effective on thick calluses.
How to use:
Soak the feet for 10-15 minutes to soften the cuticle.
Make gentle circular movements of pumice stones 2-3 times a week for up to 5 minutes each time.
Electric foot gear
How it works: Rotating grinding tips (such as mineral sand or emery) can quickly remove dead skin.
WHEN: For those with thick calluses or those looking for effective results. Suitable for daily home care. Advantages: Fast (can treat one foot in 1 minute), adjustable thickness (like the Scholl Velvet Smooth).
Weaknesses: It requires rechargeable batteries, is noisy and can cause sensitive skin to turn red.
Description:
Apply to dry skin (avoid slipping).
Start at a lower position and gently apply in the same direction for no more than 2 minutes at a time.
Manual Foot Rasp/Callus Shaver
Mechanical device: A metal blade or file for scraping and peeling.
For: professional pedicure shops or thick callus first aid.
Strengths: Quick results, suitable for local calluses.
Weaknesses: Skills are needed (to avoid cutting), posing a higher risk to household use.
Safety Tips:
For professional use only;
Blades must be disinfected to prevent cross-contamination.

ii. Chemical Softening Tools (for sensitive skin or deep calluses)
Products containing salicylic acid/urea
Mechanism of action: Chemical composition softens the cuticle and promotes natural exfoliation. Commonly used forms:
Ointment (e.g., 17% urea ointment): Apply to calluses every night;
Patch (like Dr. Scholl's Callus Remover): Contains 40% salicylic acid for 24-48 hours.
Strengths: Painless and suitable for diabetics or people with poor circulation.
Weaknesses: Requires continuous use (2-4 weeks), which can lead to local peeling.
Description:
Use after cleansing;
Avoid contact with healthy skin to prevent irritation.
Callus Softening Solution
How it works: Contains glycolic acid or lactic acid, which softens calluses quickly.
Usage: Pre-treatment before pedicure to reduce damage to body.
Strengths: Quick penetration (5-10 minutes effective) and can be used with foot resurfacing equipment.
Weaknesses: There may be slight tingling, so sensitive skin may need dilution.
