Callus on the foot


The human skin consists of a multitude of layers, each of which has a different structure, as each of them has to fulfill a different function. The outermost layer of the skin, the so-called epidermis, is divided into five layers: from the inside out, these are the

  • Basal layer
  • Prickly cell layer
  • Granular layer
  • Gloss layer and
  • Horny layer (stratum corneum)

The majority of the cells in the epidermis are made up of the horn-forming cells (Keratinocytes) formed, which gradually become the Horn cells (Corneocytes) develop.

The cornea consists entirely of corneocytes. These cells are actually already dead and therefore no longer contain any cell organelles (nucleus, mitochondria, etc.). Between the individual cells there are fats that help keep the horny layer in their Protective function is supported.

Usually the horny cell layer consists of 12 to 200 layers, depending on which part of the body you examine the skin. Further inside, the individual cells (with the help of so-called desmosomes) still form contacts with one another, further towards the surface, in the outermost layer of the horny layer, also known as Stratum disjunctum referred to as.

The cell contacts dissolve, as a result of which the individual horn cells can separate from one another and be removed from the skin. This process is whole natural and necessaryto the skin gradually renew. It usually occurs without these flakes becoming visible to the human eye. Only if there is a fault in the process and, as a result, aggregates of 500 or more cells suddenly detach themselves from the skin, one can do this in the form of Dander detect.

Functions of the cornea

The cornea has an extremely important task for our body. It practically forms one Barrier between the human body and the outside world. On the one hand, it serves as a protection from external influences. In order to be able to penetrate the body, bacteria, viruses and other germs first have to overcome the skin barrier, a hurdle that many microorganisms already fail to overcome.

But our cornea also protects us from mechanical loads: regions that increased pressure or friction are exposed to react with a increased production of cornea.
With the help of the fats that are stored between the corneal cells, the cornea also accomplishes another important task, namely it works through it water repellent and protects the body from unnecessary water retention and also from the dry out.

From the above facts it follows that you have a relatively thick cornea classically on the soles of the feet thinks, because you run on it all the time. On the other hand, a thick callus can develop in unusual places on the foot, for example due to the Wearing too tight or incorrect footwear.
Even playing stringed instruments like a guitar frequently can lead to Callus formation on the fingertips to lead. It is therefore clear that in principle every area of ​​the skin with a excessive corneal production can react if the corresponding stressful circumstances exist.

Pathological corneal development

In rare cases, however, the overproduction of cornea can also exceed a normal, healthy level and thus become pathological and even dangerous under certain circumstances. Then the cornea thickened Signs of chronic inflammation of the skin (dermatitis) and often changed pitted. This is then referred to as Horn or skin calluses or Tylom.

Probably the best known example of this is that Corns. A corn is understood to be a Growth of the cornea (Hyperkeratosis). This is mostly round and between 5 and 10 millimeters big. In the middle there is a mostly yellowish translucent horn wedge (which represents the "eye"), the tip of which is directed downwards and that through the Applying pressure to the underlying tissue can lead to pain.

Ever deeper this spur is enough, the more the corn is more painful usually. The callosity of horns comes about because the corresponding part of the body is covered by thicker, harder skin better protect against external influences tries.

The most common trigger is chronic pressure or friction, especially on skin near the bone. On the sole of the foot, they usually develop near the heads of the metatarsals. The corns are often found on the toes near the toe joints.

They usually make corns no further health risk and are therefore usually only treated if a increased risk for the development of complications or they affect the patient marked feeling of discomfort trigger.

Reasons for the removal of calluses on the foot

It is usually not necessary to remove calluses as they are a natural part of the body and help protect underlying tissues. Even if it is thicker in some areas than others or is considered "normal", there is usually no need to remove the cornea.

The only exception is corns, if they are associated with a high risk of complications (see above) or if the cornea is accompanied by cracks in the skin, which can sometimes be very painful, especially if they reach the blood vessels.

However, many people find a visible cornea uncomfortable and unsightly, which is why they want to remove it. First of all, however, it is important to understand that this can be a lengthy process and by no means go overnight. As long as the cornea takes to develop (On average, a layer of cornea a few millimeters thick takes about a few weeks to develop), you should plan until it has completely disappeared. There are several options available for this, which should be used depending on the severity of the cornea and individual preferences.

On the one hand, salicylic acid has antimicrobial effectwhich is useful in the case of corneal treatment to prevent it inflame damaged skin areas and colonize with germs, especially if they have been caused by previous treatment measures such as planing or sanding more susceptible to external stimuli are than they normally would be.

In addition, salicylic acid has from one Concentration of 5% also one keratolytic (horn-releasing) effect. This effect is due to the fact that the substance that under normal circumstances ensures the cohesion between the individual cells through the Acid dissolved out and the cells are so different from each other and from the remove intact skin to let. From one Concentration of 10% the salicylic acid becomes Treatment of corns and warts used.
These solutions must applied locally be to the To dissolve the horny layer. It is important that the healthy skin not in contact with large areas comes with the remedy, otherwise it can be affected. Salicylic acid works acutely irritating on skin and mucous membrane, which means that it is too

  • Redness
  • itching and in the worst case even to
  • Tissue damage

can come.

Chronic exposure to the acid can even cause it to Disorders of the gastrointestinal tract to lead. All other side effects known from salicylic acid, such as Respiratory depression or liver or kidney damage only if taken orally this drug before.

Another common ingredient in callus creams is urea (urea). This has a double positive effect on the excessive cornea: On the one hand, it acts as a natural moisturizer. Urea ensures that the skin cells absorb more moisture and can also save it. Creams containing urea, which are only used against dryness, usually contain 3 to 20% urea. On the other hand, it also acts directly on the cornea, whereby to achieve this effect, higher concentrations by 40% needed.

Ointments that are also often used Collodion either in an alcohol or ether solution contain. Further horn-dissolving substances (the technical term for this is keratolytics) are:

  • Retinoids (for example adapalene and tretinoin),
  • Azelaic acid
  • Benzoyl peroxide and
  • Fruit acids (for example lactic acid, mandelic acid and glycolic acid).

The cornea forms an important boundary layer between the outside world and the body.

One should be by applying these lotions no improvement or require professional assistance for other reasons, a so-called Podiatrist (a trained podiatrist) who is particularly familiar with corns and calluses on the foot and can arrange an individually tailored therapy or carry it out himself.

Professional treatment is necessary and important, especially for corns, and always has the goal of To remove horn wedge or to dissolve and thus remove (e.g. with the help of tweezers).
