How to treat corns?


Hello Dr.
Jiang: My father has developed a corn on his finger.
What medications are available on the market for treatment (I've heard that patches are not very effective)?

tom, 30~39 year old female. Ask Date: 2008/03/25

Dr. Jiang Yujiao reply Dermatology


Dear Tom: The "corns" that typically appear on the fingers are likely viral warts.
The quickest method for treatment is cryotherapy using liquid nitrogen, which can be performed at a dermatology clinic.
Wishing you safety and health.
Sincerely, Dr.
Jiang Yu-Jiao, Director of Dermatology, Taoyuan Hospital, Department of Health.

More Info


Corns, or calluses, are thickened areas of skin that develop in response to repeated friction or pressure. They commonly occur on the fingers and can be quite uncomfortable, especially if they interfere with daily activities. When it comes to treating corns on fingers, there are several effective options available, both over-the-counter and through professional medical treatment.

1. Over-the-Counter Treatments: There are various topical treatments available that can help soften and remove corns. Salicylic acid is a common active ingredient in many corn removal products. It works by exfoliating the thickened skin and promoting the shedding of the corn. These products come in the form of pads, gels, or ointments. However, it is essential to follow the instructions carefully, as overuse can lead to skin irritation or damage to the surrounding healthy skin.

2. Corn Pads and Cushions: While you mentioned that adhesive pads may not be effective, they can still provide some relief by cushioning the area and reducing pressure on the corn. These pads can help alleviate pain while the corn heals. It’s important to choose pads that are specifically designed for corns, as they often have a hole in the center to relieve pressure directly on the corn.

3. Soaking and Exfoliation: Regularly soaking the affected fingers in warm, soapy water can help soften the corn. After soaking, gently exfoliating the area with a pumice stone or foot file can help remove some of the thickened skin. This should be done with care to avoid damaging the surrounding skin.

4. Moisturizers: Keeping the skin moisturized can help prevent the formation of corns. Using a thick moisturizer or a specialized foot cream can help keep the skin supple and reduce friction.

5. Professional Treatment: If over-the-counter treatments do not provide relief, it may be beneficial to consult a healthcare professional. A dermatologist or podiatrist can assess the corn and may recommend more aggressive treatments, such as:
- Debridement: A professional can safely remove the corn using sterile instruments, which can provide immediate relief.

- Custom Orthotics: If the corn is caused by foot mechanics or improper footwear, custom orthotics may be recommended to redistribute pressure and prevent recurrence.

- Surgical Options: In rare cases, if the corn is recurrent and painful, surgical intervention may be necessary to correct any underlying issues.

6. Preventive Measures: To prevent corns from forming in the first place, it is crucial to identify and address the source of friction or pressure. This may involve wearing properly fitting gloves or using protective padding when engaging in activities that put stress on the fingers.

In summary, while there are various over-the-counter treatments available for corns on fingers, their effectiveness can vary from person to person. It is essential to approach treatment with a combination of methods, including topical treatments, cushioning, and proper skin care. If the corn persists or causes significant discomfort, seeking professional medical advice is recommended. Your father should also consider preventive measures to avoid future occurrences.
