Corns are thickened and hardened layers of skin that form on the points of pressure or friction on the feet. They can cause pain and discomfort, especially when walking or wearing shoes. There are different ways to treat corn, such as surgery, medicated patches, or home remedies.
Some of these methods may leave a white spot on the skin after corn removal. What is this white spot, and is it something to worry about? Here is what you need to know.
Why Does a White Spot Appear After Corn Removal?
The most common reason is the use of salicylic acid, which is an ingredient in many over-the-counter products for corns, such as patches, gels, or liquids.
Salicylic acid works by softening and shedding the dead skin cells that make up the corn. It can also affect the healthy skin around the corn, causing it to turn white temporarily. This is because salicylic acid reduces the amount of melanin, which is the pigment that gives color to the skin.
Another possible reason is skin damage or infection. If the corn is removed by cutting or scraping with a sharp object, such as a scalpel or a razor blade, it can injure the skin and cause bleeding or scarring.
This can also affect the production of melanin and result in a loss of color in the affected area. Additionally, if the wound is not properly cleaned and disinfected, it can become infected by bacteria or fungi, which can also alter the appearance of the skin.
How Long Does It Take for the White Spot to Fade?
The duration of the white spot depends on several factors, such as the size and depth of the corn, the type and amount of salicylic acid used, the sensitivity of the skin, and the healing process of the wound. In general, it may take from a few days to several weeks for the white spot to fade and return to its normal color.
In some cases, the white spot may persist for longer or even become permanent. This can happen if there is extensive damage to the skin cells or melanocytes that produce melanin.
For example, if the corn is very deep or large, or if there is excessive use of salicylic acid or other harsh chemicals, it can destroy or damage the melanocytes irreversibly. This can lead to hypopigmentation, which is a condition where the skin lacks pigment and appears lighter than normal.
How to Prevent or Treat a White Spot?
The best way to prevent or minimize is to avoid using products that contain salicylic acid or other harsh chemicals that can irritate or bleach the skin.
Instead, opt for gentle and natural methods to treat corns, such as soaking your feet in warm water with Epsom salt or baking soda, rubbing them with a pumice stone or a washcloth, applying moisturizer or oil to keep them hydrated, and wearing comfortable shoes that fit well and do not cause friction.
If you do use salicylic acid products for corn removal, make sure to follow the instructions carefully and use them sparingly. Do not apply them on open wounds or infected areas, as this can worsen the condition and increase the risk of complications.
Also, protect your skin from sun exposure by wearing sunscreen or covering up with clothing, as this can help prevent further discoloration.
If you have a white spot that does not fade within a few weeks or causes pain, itching, swelling, redness, or signs of infection, you should consult your doctor or podiatrist for diagnosis and treatment.
Depending on the cause and severity of your condition, you may need prescription medications, such as antibiotics or steroids, to treat infection or inflammation. You may also need cosmetic procedures, such as laser therapy or skin grafting, to restore pigment or improve appearance.
A white spot after corn removal is not a cause for alarm, but a sign of healing. However, you should still monitor the affected area for any signs of infection, such as redness, swelling, pain, or pus. If you notice any of these symptoms, contact your doctor immediately.
Otherwise, you can expect the white spot to fade away gradually as your skin regenerates. To prevent future corns, make sure to wear comfortable shoes that fit well and avoid excessive friction or pressure on your feet.
