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. This can cause pain and discomfort if left untreated. 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 like calluses, are caused by pressure and 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 correctly, 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 around the heel or toes which then creates extra pressure on the foot in the shoe. Foot corn removal must be done carefully and may take a little time as the skin needs to be softened.


A callus is an area of thick, hard raised 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. If the callus causes discomfort or is unsightly then a “callus remover” product like Kroko Corn and Callus remover can help to treat the problem, and Kroko foot powder can also help to make feet more comfortable. This will act to soften the skin so that the callus can be carefully removed with a pumice stone, foot file or Pedi Egg.


Why do I need to remove a corn from my foot?

The reason for removing a corn or callus would be to try and treat the root causes of the pressure on the foot and try to relieve any resulting pain or discomfort. Where a callus has become raised, inflamed and thickened and turned into a corn over time due to fiction and pressure against a shoe or another toe, it is advisable to treat it especially if it is causing pain or discomfort. Unfortunately, these symptoms will not go away if left untreated and with time may get worse.

Foot pain is something that can have a large impact on the quality and enjoyment of our life especially when we are up on our feet at work for many hours, or during our leisure time. By engaging with a corn treatment plan quality of life can be improved for the sufferer. Foot corn removal is a relatively easy process however, the treatment may take up to 2 weeks of daily attention. Do not try to cut off corns or calluses yourself. Please follow the process below in the question on “How to remove a corn”. It is also advisable to try and establish the root cause of the corn and then take steps to address this problem carefully. The formation of the corn would have been caused by pressure or friction over the affected tissue due to ill fitting socks or shoes.

Softening your feet each day with Kroko Heel Balm and using Corn protector plasters can not only help to prevent cracked heels but will help relieve pressure and discomfort as well. If possible, always ensure that your shoes fit correctly and try and rotate them so that you are not wearing the same pair each day. This is important so the same shoes do not rub against skin you have just treated; you don’t want this softer skin being exposed to the same pressure or friction that caused the original corn or callus.


How do I remove a corn or callus from my foot?

To ease the pain and discomfort 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 a corn treatment 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 treat or remove corns follow this method:
  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.

Diabetics: Please consult your doctor before using products containing Salicylic Acid on your feet.


Always read the instructions.

What is a wart?

Common warts are caused by several variations of the Human Papilloma Virus (HPV) and are small benign fleshy growths on the skin usually light grey, pink or brown in colour. The virus accelerates extra cell growth which then causes the outer layer of skin to harden and thicken in that area. It is easier for broken, cut or damaged skin to become infected, so these conditions should always be cleaned as soon as possible. Most people will get warts at some point in their life, and they affect around 10% of the population with the incidence of infection being higher (10% to 20%) in children. Common warts are contagious and can be found on any part of the body (though more often on the knees, elbows, fingers and hands). They can be spread through direct contact (skin to skin) and indirect contact (using someone else’s towel or razor). So, avoiding these types of skin contact is good skin hygiene practice. As they are commonplace - a popular question which naturally arises is how to remove a wart.


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 and can linger for up to 2 years at a time, so most people do look for wart treatment or wart removal remedies to treat them rather than waiting for them to fall off which may take a year or two. Severe cases can last longer. Warts can also return and there is no sure way to prevent them, so avoiding contact with someone else’s warts and good skin hygiene are important aspects to consider. Wear flop flops or waterproof sandals in public swimming pools, showers and change rooms to reduce the risk of infection in the feet.


How can I get rid of a wart?

Common Warts can be successfully treated at home or by a doctor. Kroko WartFix is a simple and easy to use wart removal treatment. It is important to follow the instructions for effective wart removal.


Kroko Wart Fix is a flexible liquid application for warts which forms a waterproof covering over the wart.

Instructions for wart removal treatment:

  • 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.

A doctor can also cut off a wart or use a special instrument to scrape it, but this may be painful and leave scarring. 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.

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. Anyone suffering from genital warts should consult their doctor. Kroko wart removal and wart treatment products are not suitable for treating genital warts. Kroko WartFix must not be used on the face or sensitive skin.

What causes cracked heels?

Many people suffer from cracked heels. Cracked heels or heel fissures are caused by standing too long, wearing ill-fitting shoes, having 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. Cracked heels can be painful if left untreated.


What can I do 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 to prevent as well as 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 cracked heel treatment like HeelFix 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 HeelFix is a clear liquid plaster which can be painted over skin fissures to help them heal, preventing them drying out further. HeelFix creates a hygienic, flexible, moisture and dustproof barrier which allows natural healing to take place. Do not use on open wounds which are infected or inflamed, or cracks that are bleeding.


Directions for use

  1. Clean the feet well and dry thoroughly.
  2. Apply a thin layer of HeelFix to cover the heels.
  3. To renew dressing, apply more HeelFix to the old dressing which will soften and can be gently wiped off using a clean dry swab. 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 can I 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.
