Colloquially and also in the cosmetic sense, there is talk of cornea when excess thickening of the outer skin layer builds up. This happens primarily on the feet and is often perceived by those affected as annoying, even if the cornea does not normally pose a risk from a medical point of view. The cornea can be removed using various methods, and injuries to the deeper layers of the skin should be avoided as a matter of urgency.
Definition and function of cornea
Cornea is actually something quite normal. It is the outermost layer of our skin, called the stratum corneum. This skin layer is very thin on the whole body. Your main task is to form a protective shield against external influences. If certain areas, such as the fingertips or heels on the feet, are mechanically stimulated, more of this horny layer is formed to protect against stress.
The cornea on the hands and feet becomes thicker to protect against pressure and friction in stressed areas. The stratum corneum consists of dead, horny cells called "corneocytes". Fat cells are stored in between, making the horny layer a water-repellent protective cover.
Where cornea is most common
Cornea is most common on the hands and feet. It serves to protect sensitive areas. A thin corneal layer is therefore completely normal. However, excessive thickening can cause pain. In addition, most people find the cornea extremely unsightly and want to remove it. The thicker it is, the more it becomes inflexible, can tear, dry out and thus cause pain. Especially on the feet, which are exposed to constant stress, a very thick horny layer can form.
The causes of a thick cornea are, for example, friction and pressure, which are triggered by shoes that do not fit properly, are too small and do not leave enough space for the feet. Also, professions that require long standing or running will sooner or later develop corneas in the heavily used areas.
In summer, when walking barefoot frequently, cornea also forms on the sole of the foot to protect the foot. However, this is completely normal and makes sense. Hands can also be affected by increased cornea formation, such as the fingertips when playing the guitar or the palms of the hands after long gardening. People who do heavy work with their hands often have so-called calluses on the particularly stressed skin areas.
Increased body weight can cause one-sided or incorrect loads, which leads to an increased formation of the cornea. Other possible causes include deformities of the feet or the existence of a disease such as diabetes. People who tend to have dry skin, such as during menopause, tend to thicken the skin on their feet. Sometimes the drought creates cracks in the cornea, which can be extremely uncomfortable. In this case, it is especially important that you apply cream to your feet every day for care.
Methods of removing the cornea
Various methods are possible to remove cornea. In any case, caution is advised. Important: Under no circumstances should scissors or sharp blades be used, as this increases the risk of injury and the cornea grows back more easily and quickly even after removal. Helpful methods are footbaths, pumice stones, files, rasps, creams and various home remedies.
Special care should be taken with diabetics. You should always have calluses removed by professional podiatrists to avoid injury. Cornea is an increased risk of the dreaded ulcers in diabetics and should therefore be controlled regularly.
Corneal removal with pumice stone
To gently remove cornea, the pumice stone is ideal. It originally consists of porous volcanic rock. Nowadays, natural products are often no longer used, but pumice is manufactured industrially. It can be used both dry and wet. Rubbing the horny layer with the pumice stone is a gentle way of removing the thickened skin. However, this usually has to be done regularly in order to be successful. Since the stone rubs off, it must be replaced after a certain time. Solid corneas cannot always be removed using this gentle method.
Foot baths are a pleasant way to remove cornea or to prepare the feet for further treatment. At the same time, this can counteract the new formation of thick skin. In general, the bathing temperature should not be too hot and the bathing time should not exceed twenty to twenty-five minutes. Depending on your preference, salt, fruit vinegar, tea tree oil, baking soda or Schüssler salts can be used as bath additives.
You can use the foot bath e.g. Add a handful of Himalayan or sea salt and stir until the salt has dissolved. About 250 milliliters of fruit vinegar are added. To use tea tree oil, first mix three to four drops with a little cream or olive oil and then mix into the prepared foot bath.
Soda is also known to be able to dissolve the horny layer somewhat. About three teaspoons of baking soda are necessary for this, which are first mixed with a few spoons of water and then added to the bath water. Schüssler salts are suitable for both internal and external use. Here is the No. 1 salt, calcium fluoratum, the drug of choice for removing dry skin and calluses. This is dissolved in hot water, mixed with a plastic or wooden spoon and then added to the foot bath.
Care should be taken when removing cornea with the rasp. As with the application with the pumice stone, the excess cornea is removed by rubbing. However, it should be noted that the skin can be particularly easily injured by the rasp. It is best to soften the skin (for example with the help of a foot bath) before use, since the dry application can more easily lead to injuries. It is important to make sure when buying that the choice falls on a rasp that has a fine grinding surface.
Using an electric cornea slicer is a convenient, easy, and gentle way to tackle thick skin. The electrical devices that are intended for domestic use generally enable gentle and easy handling. To tackle massive corneas, professional foot care from a specialist is the better solution. Because devices are used here that may only be used with the appropriate specialist knowledge.
Creams for dry feet and calluses
Applying special creams against the cornea is a good method, which requires a little patience, but is usually quite effective. Often these creams contain salicylic acid, which helps remove the cornification. Another active ingredient is urea, which makes the thick horny layer a little more flexible and softer. The combination of pumice stone and cream is recommended.
The ointment No. 1 from mineral therapy with Schüßler salts is not a special corneal ointment, but can be used quite successfully in this case. However, regular and long-term use is necessary here, since the cream does not work overnight.
Remove home remedies for the cornea
Various home remedies can help to get rid of annoying calluses and calluses. In any case, it is important that the feet (or the affected skin areas) are frequently applied cream to avoid dryness. A cream pack that works best overnight. For this purpose, the feet are thickly creamed with deer tallow ointment, fat cream or calendula ointment in the evening before going to bed and put in cotton socks. This should be done daily for a long period of time.
Placing lemon slices on the thick cornea can be useful to remove it. Applying 100% aloe vera juice is just as helpful. An ancient method is to put on chamomile packets. To do this, chamomile flowers are packed in a fabric bag, tied up, poured with boiling water and then, if this is no longer too hot, placed on the affected areas.
An effective method for beautiful feet is a peeling, for which sugar or salt is mixed with a little olive oil. Rub your feet with it two to three times a week. The cornea can usually not be completely removed by the peeling, but in any case the feet are really nice and soft afterwards.
Foot care with olive oil and valuable medicinal plants such as wild garlic has a smoothing effect on brittle skin and has a healing effect on sore, cracked areas on the feet.Foot oil for dry skin
- 100 ml of good olive oil
- 10 g wild garlic
- 5 g marigold flowers
- 2 g each of rosemary and lavender flowers
Warm the oil and add the wild garlic and flowers. Let the mixture boil for three minutes, then cool and keep the medicinal herb oil in a cool place (e.g. in the basement) overnight. The next day, it is slowly heated and stirred for about 10 minutes. Let it cool to a lukewarm temperature. Then the oil is strained, poured into a vial and applied thinly to the dry areas.
The "old" core soap bath should not be missing in the list of home remedies for cornea. The feet are soaked in it for fifteen to twenty minutes, then rubbed with a pumice stone and then thickly applied.
Danger: Removing the cornea is one thing. To rub off too much of it is the other. It should be borne in mind here that a certain amount of cornea is important for protection. If this is completely rubbed off, this can lead to pain when running and unpleasant injuries.
Prevention of cornea
Cornea only disturbs most people in summer when the feet come back to light. Then an attempt is made to remove the unsightly spots as quickly and successfully as possible. However, the feet have to wear the body all year round, whether in winter or summer, are pressed into tight shoes and are often treated like “stepchildren”. It is therefore better to pay more attention to your own feet every day.
Among other things, it is recommended to regularly rub unnecessary cornea with a pumice stone, a weekly salt or sugar peeling for the feet, to wear cotton socks and comfortable shoes. A relaxing foot massage carried out every now and then rounds off the "pampering program" for healthy feet.
Particular attention should also be paid to footwear: if the feet are pressed too often into shoes that are too tight, a thick cornea easily forms. Accordingly, you should always pay attention to suitable and well-fitting footwear and under no circumstances should you wear a smaller size than necessary out of vanity. Special foot exercises and frequent barefoot walking support the health of the feet. (sw, nr)
