Frequently Asked Question

What is the difference between a corn and a callus?

A corn is a raised nodule on the top or sides of the toes usually on the toe joints, with a hard nucleus or core which bores into the tissue pressing on the tissue and nerves. Corns are mainly found on the top of toe-joints or on the side of feet and are raised, shiny domes of hard thickened skin with a hard nucleus or centre. Corns are similar to calluses are caused by friction on the skin. Corns can cause pain and get inflamed when they press on a nerve in the foot or against a hard shoe, so it is important for your foot health and comfort to remove a corn as soon as it appears.

Corns can usually be avoided by wearing shoes that fit properly, are neither too loose or too tight, are not pointed and do not rub and cause friction. A useful tip when buying shoes is to consider trying on a pair at the end of the day when your feet could be warm and slightly swollen after being stood on all day. It is also good to remember to wear socks that are the right size and not too small or too large which will also cause the toes to bunch up and rub against the shoe.

A callus is an area of thick, hard skin on sides of the large toes or underneath the food caused by repeated friction or pressure from shoes or socks which are too tight.


Do you need to remove a corn?

It is advisable to remove a corn because they can be painful when pressing against a shoe and can become red and inflamed from the friction. They are relatively easy to remove but the treatment may take up to 2 weeks.


How to remove a corn

To ease the pain of a corn, you can use a corn pad to remove the excess pressure. Corn pads are donut shaped cushioned plasters with a hole in the centre for the corn sit in and to protect it from chaffing.

Corns are easily removed using an ointment like Kroko Corn and Callus remover which has been a tried and trusted remedy since the 1930s or a medicated Corn Plaster which contains a dose of salicylic acid in a corn protector which protects and cushions the corn while treating it. Kroko CornFix is a liquid application which covers and treats the corn and comes packed with 6 corn protectors which can be used during treatment.

To get rid of a corn:

1. Soften the corn by bathing in hot water.
2. Dry thoroughly.
3. Please note. It is important to mask the area surrounding the corn to protect the healthy skin, either by covering the area with a piece of adhesive plaster in which a hole the size of the corn has been cut or use a suitably sized adhesive corn ring. Alternately protect the healthy skin around the corn with a layer of Vaseline. The corn will then be exposed in the open hole in the centre of the plaster or Vaseline.
4. Apply the ointment so that it covers the exposed corn.
5. Cover the corn with a second piece of plaster or a corn protector.
6. Change the dressing every second day until the corn peels off in layers. It usually takes about 8 days for the corn to be removed but resistant cases may take longer. Do not administer the ointment for longer than 14 days.

*WARNING: Do not apply to healthy skin or near the face and eyes.

Always read the instructions

What is a wart?

Common warts are small fleshy growths on the skin usually light grey, pink or brown in colour. Common warts occur when the skin becomes infected with a contagious virus called HPV. This virus can be picked up by direct contact with a person who has a wart or by coming into contact with the same surface that a person with a wart has touched. Warts are fairly commonplace so a popular question which naturally arises is how to remove a wart.

Warts are most frequently found in children but can appear at any age and can be found on any part of the body. They are usually found on knees, elbows, fingers and hands. 

Plantar warts are flattened growths which occur under the foot usually on the sole of the foot. These can be painful and may need to be removed by a doctor as they can penetrate deep into the foot.

Most warts are a minor inconvenience and not a serious, life-threatening condition but they may cause some discomfort or embarrassment as they can be unsightly so most people do look for remedies to remove them rather than waiting for them to fall off which may take a year or two. Warts can also come back.


How can I get rid of a wart?

Warts can be successfully treated at home or by a doctor. 

PLEASE NOTE: Diabetics who have issues with their feet or people who suffer from nerve damage in the feet, neuropathy, must consult a doctor to for treatment rather than use a home remedy. It is also recommended to consult a doctor if you have a plantar wart under the foot which may need to be cut or cauterized with liquid nitrogen. This is called cryotherapy. 

There are a number of old wives’ tales type remedies for removing a war at home; these are cheap and cost-effective but we can’t vouch for their effectiveness. These include using:

- Clear nail polish
- Hydrogen Peroxide
- Tea Tree Oil
- Sliced garlic and oil
- Duct tape
- Rubbing with raw potato

A doctor can also cut off a wart or use a special instrument to scrape it but this may leave scarring.
For a tried and trusted solution to removing a wart we recommend Kroko Wart Fix.

This is a flexible liquid application for warts which forms a waterproof covering over the wart. To use if follow these instructions:

- Soak foot in hot water for 5 minutes and towel dry.
- Rub corn with a pumice stone or emery board.
- Mask off the skin around the wart with Vaseline or cut a hole in a plaster and stick if over the wart with the wart sticking through. This is to protect the healthy skin from the acid in Wart Fix.
- Apply Kroko Wart Fix to the wart using the applicator (avoiding the surrounding skin).
- Allow to dry and cover with a plaster if necessary.
- It is important to reapply twice a day until the wart has cleared. This can take up to 2 weeks.

NOTE: Kroko WartFix is not to be used on the face. It is for external use only and is not to be used on genital warts.


Where can I buy WartFix?

Kroko WartFix is available at all good pharmacies and selected Clicks stores in South Africa. Kroko is also available in Namibia, Botswana and Zambia – please ask your pharmacist to order it if they don’t have stock.


How to treat cracked heels or heel fissures?

What causes cracked heels?

Many people suffer from cracked heels which can be painful if left untreated. Cracked heels or heel fissures are caused by standing too long, wearing ill-fitting shoes, dry skin, going barefoot or wearing open heeled sandals, having flat feet, diabetes, neuropathy or psoriasis. When weight and pressure are applied to the foot when standing, walking and exercising, the plump pad under the heel, pushes outwards and puts pressure on the skin. If the skin is dry and lacking in moisture, it becomes stiff and less elastic so the skin can crack and develop fissures in the heels.

How to treat cracked heels

Selfcare is important and cracked heels can be prevented or at lease minimised. An emollient heel balm containing Urea like Kroko Heel Balm can be used treat cracked heels. Emollient creams penetrate the skin and reduce water loss filling the gaps in the skin which makes skin feel smooth, soft, and flexible. Alternately, a liquid plaster like Kroko SkinFilm can be painted over the cracks to hygienically seal them and allow healing.

Kroko Heel Balm gently softens and hydrates rough, dry and cracked heels (and elbows) leaving skin smooth and soft.

Directions for use

1. Soften the heels by bathing in hot water to remove flaking skin. If there is very thick callused skin on the heel buff this with soap and a pumice stone to remove excess dry skin. Note try to keep baths and shower to 5 minutes to prevent skin drying out.
2. Dry feet thoroughly.
3. Rub Kroko heel balm into heels thoroughly morning and evening.
4. For even better results, after applying cream in the evening cover with socks while sleeping to lock in the moisture.
Kroko SkinFilm is a clear liquid plaster which can be painted over skin fissures to help them heel, preventing them drying out further. SkinFilm creates a hygienic, flexible, moisture and dustproof barrier without the bulkiness of a plaster which allows natural healing to take place. SkinFilm must not be used on open wounds which are infected or inflamed.

Directions for use

1. Clean the feet well and dry thoroughly.
2. Apply a thin layer of SkinFilm to cover the heels.
3. To renew dressing, apply more SkinFilm tp the old dressing which will soften anc can be gently wiped off using a clean dry swab. Renew dressing as needed until healing is complete.
4. Apply a thin layer of SkinFilm to cover wound completely using the applicator cap. SkinFilm dries quickly leaving an invisible, hygienic, flexible dressing allowing natural healing to take place.
5. To renew dressing, apply more SkinFilm to the old dressing which will soften and can be gently wiped off using a clean dry swab or lint. Renew dressing as needed until healing is complete.

In severe cases where heels become inflamed or the cracks become infected, speak to your doctor as severely dry, cracked heels may be a sign of an underlying health condition like neuropathy or diabetes.

How to prevent cracked heels

Losing weight, moisturising your feet or most importantly wearing properly fitting, closed shoes and socks can help prevent heels cracking. 

To combat dry skin, moisturise your feet when you moisturise the rest of your skin. This provides a protective barrier over your skin and prevents water from escaping and the skin from drying out. It is best to moisturise feet at night so the cream can be absorbed into the skin which will prevent them becoming slippery and sweaty during the day. Wearing a pair of socks after moisturising will help prevent them drying out overnight. 

Gently rubbing a pumice stone against the thickened skin on the heel, once the skin is moisturized, may help reduce the thickness of the hard skin and calluses. Be particularly gentle if you suffer from neuropathy or diabetes and avoid foot files or using scissors to cut away dry skin.
