Skin hyperkeratosis is a condition in which the top layer of skin, called the epidermis, becomes thicker and tougher due to excess keratin production. Keratin is a protein that is naturally present in the skin, but in hyperkeratosis, its production increases, resulting in thickened and coarser skin.
Causes of the hyperkeratosis
Below are some of the most common causes of hyperkeratosis:
- Mechanical exposure: Constant friction, pressure and mechanical irritation of the skin can lead to hyperkeratosis. For example, calluses on the feet can form due to the friction of shoes.
- Age: As we age, skin renewal processes slow down and the epidermis becomes less able to remove excess keratin. This can lead to a natural thickening of the skin.
- Medical conditions: Some medical conditions such as psoriasis and keratosis.
- External factors: Exposure of the skin to harsh chemicals, including household or professional chemical skin care products.
- Heredity: Genetic factors may increase susceptibility to hyperkeratosis.
- Environmental pollution: Prolonged exposure to a polluted or dry atmosphere can provoke thickening of the top layer of skin.
- Use of medications: Some medications can cause hyperkeratosis as a side effect.
- Sun exposure: Prolonged exposure to ultraviolet rays from the sun can increase the risk of hyperkeratosis and other skin changes.
Pathogenesis
The pathogenesis of hyperkeratosis is related to excessive formation and accumulation of keratin in the upper layers of the skin. The process of pathogenesis of hyperkeratosis can vary depending on its cause and type. Here is a general scheme of pathogenesis:
- Stimulation of keratin production: Under the influence of various factors such as mechanical impact, external irritants, genetic changes or medical conditions, the skin can begin to actively produce keratin.
- Increased cell renewal rate: The skin is constantly renewing itself by exfoliating the upper layers and forming new cells in the deeper layers of the epidermis. Under the influence of hyperkeratosis, the cell renewal process may be accelerated.
- Disruption of the exfoliation process: One of the key points in the pathogenesis of hyperkeratosis is the disruption of the normal process of exfoliation of old cells from the surface of the skin. This results in rough and thickened cells remaining on the surface.
- Increased keratin layer: As a result of accelerated keratin production and impaired exfoliation, skin cells become thicker and contain more keratin, making the skin tougher and rougher.
- Symptoms: Hyperkeratosis presents with a variety of symptoms depending on its location and type, including skin coarsening, calluses, horny patches, and other changes.
Hyperkeratosis is often a defense mechanism of the body in response to irritants or mechanical action. It can also be an adaptive response to certain conditions or pathologies.
Symptoms of the hyperkeratosis
Symptoms of hyperkeratosis can vary depending on its type and location on the skin. However, some common symptoms may include:
- Rough skin: Hyperkeratosis is usually accompanied by rough, thicker skin on the affected areas.
- Skin stiffness: Areas of skin with hyperkeratosis may become stiffer and less mobile.
- Dryness and roughness: Skin with hyperkeratosis may be dry and rough in rough areas.
- Calluses: The most well-known symptoms of hyperkeratosis are calluses, which form on the feet or toes due to mechanical impact and friction.
- Hornypatches: Hyperkeratosis can also cause horny patches to form on the skin, such as on the elbows or knees.
- Pain and discomfort: Some forms of hyperkeratosis can cause pain and discomfort in the affected areas of the skin.
- Changes in nail appearance: Hyperkeratosis in the nail area can lead to nail changes and deformities.
- Skin irritations: Hyperkeratosis may cause irritation and itching in the affected areas of the skin.
Symptoms may vary depending on the specific cause and location of hyperkeratosis. For example, hyperkeratosis on the soles of the feet may appear as painful calluses, while on the elbows it may appear as horny areas. It is important to pay attention to the symptoms and consult a dermatologist or physician for diagnosis and appropriate treatment.
Stages
Hyperkeratosis can have different stages, and their nature can vary depending on the location and cause of the condition. However, common stages of hyperkeratosis include:
- Initial stage: In the initial stage of hyperkeratosis, the skin may show the first signs of coarsening and thickening. This may manifest as mild dryness and roughness of the skin. In this stage, the changes usually do not yet cause pain or discomfort.
- Progressive stage: As hyperkeratosis develops, rough skin becomes more visible and thickens. Calluses and horny areas may form, which can become painful and cause discomfort when pressure or friction is applied.
- Complication stage: If hyperkeratosis is left untreated or exposed to long-term negative factors, it can lead to complications. These can include inflammation, cracks, infections, and other skin problems that can worsen symptoms and require more serious treatment.
The extent and nature can vary depending on its cause, location and how long it has been present on the skin.
Forms
Hyperkeratosis can occur in different forms and in different areas of the body. It can be temporary or chronic and can be caused by different factors. Below are some of the common types of hyperkeratosis:
- Calluses: Calluses are areas of hyperkeratosis that form on the skin in response to mechanical impact and friction. For example, calluses can occur on the heels or toes of people who use tools frequently.
- Calluses: Calluses are hyperkeratotic patches of skin on the feet that can occur due to wearing uncomfortable or tight shoes for long periods of time.
- Horn-like external changes: Hyperkeratosis can result in horn-like areas on the skin, such as horny areas on the nails or rough areas on the elbows and knees.
- Medical Conditions: Hyperkeratosis can also result from certain medical conditions, such as psoriasis, and can even be a sign of metabolic disorders.
- Peel keratosis: This type can be caused by chemical procedures such as chemical peels and is manifested by the exfoliation of the top layer of skin.
Diagnostics of the hyperkeratosis
Hyperkeratosis is usually diagnosed by a dermatologist or skin care professional. Here are a few methods that can be used for diagnosis:
- Visual examination: The doctor examines the affected areas of the skin. Hyperkeratosis often has characteristic symptoms such as rough and scabby skin or calluses, making it easier to diagnose visually.
- Additional tests: In some cases, your doctor may perform a skin biopsy to confirm the diagnosis and rule out other skin conditions. The skin sample is taken for laboratory testing.
- Medical History: The doctor may ask questions about symptoms, duration of symptoms, factors that may trigger hyperkeratosis, and the patient's medical history.
- Clinical analysis: Additional clinical tests are sometimes used to detect hyperkeratosis-related medical conditions such as psoriasis or keratosis.
Differential diagnosis
The differential diagnosis of hyperkeratosis involves identifying the condition and distinguishing it from other skin diseases or conditions that may mimic the symptoms of hyperkeratosis. Some of the possible differential diagnoses are summarized below:
- Psoriasis: Psoriasis psoriasis is a chronic skin disease that can also cause skin roughness and horny patches. However, psoriasis is often accompanied by characteristic signs such as redness, scales, papules and plates with silvery scales.
- Keratosis: Keratosis includes different types of skin growths such as keratosis squamous, keratosis soldatum and others. They may have similar symptoms to hyperkeratosis but differ in nature and structure.
- Calluses: Calluses are thickened areas of skin, usually caused by pressure or friction. They may be similar to calluses formed by hyperkeratosis, but may have different causes and localization.
- Contact dermatitis: This type of dermatitis occurs when the skin is exposed to allergens or irritants, and it can cause symptoms similar to hyperkeratosis.
- Medical vascular disorders: Somevascular conditions, such as varicose veins or thrombophlebitis, can cause skin changes resembling hyperkeratosis.
For proper differential diagnosis, it is important to perform a thorough physical examination, including visual inspection of the affected skin and discussion of symptoms with the patient. In some cases, laboratory tests or biopsy may be required to more accurately determine the diagnosis.

Treatment of the hyperkeratosis
Treatment of hyperkeratosis depends on its type, location, and severity. Here are some common treatments:
- Moisturizing: Regular moisturizing of the skin helps to soften rough areas and improve the overall condition of the skin. Use a quality moisturizing cream or ointment on the affected areas of the skin.
- Exfoliation: Using skinexfoliating products can help remove rough skin cells and improve skin texture. Mild peels containing lactic or glycolic acid can be effective.
- Keratolytic agents: Your doctor may prescribe keratolytic agents to help soften and remove rough skin. These products may contain urea, salicylic acid, or other active ingredients.
- Shoes: If hyperkeratosis on the feet is causing calluses, properly fitting and comfortable shoes can help reduce pressure and friction on the affected areas.
- Medical exfoliation procedures: For more serious cases, your doctor may recommend medical exfoliation procedures such as chemical peels, mechanical exfoliation, or laser therapy.
- Treatment of the underlying cause: If the pathologic condition is caused by some other medical condition, the treatment should be directed toward eliminating that underlying cause.
It is important to consult a doctor or dermatologist for an accurate diagnosis and the best treatment method for your particular case. Do not attempt to remove rough skin or calluses yourself, as this can lead to injury and infection.
Prevention
Prevention of hyperkeratosis is aimed at preventing its development or recurrence. Here are some recommendations for prevention:
- Moisturize your skin: Mo isturizing your skin regularly helps prevent dryness and roughness. Use a quality moisturizer after showering or bathing.
- Use sun protection: The sun's rays can worsen skin conditions. Use a sunscreen with an SPF protection factor to prevent skin damage from UV rays.
- Avoid prolonged skin exposure: Try to avoid long bathing sessions or swimming in chlorinated pools, as this can dry out your skin.
- Choose the right shoes: Wear comfortable and properly fitting shoes to prevent pressure and friction on your feet.
- Pedicure: Getting regular pedicures and nail care will help prevent calluses on your feet.
- Avoid heavy friction: Try to avoid rubbing the skin of your feet against each other or against your clothes for long periods of time.
- Treat the underlying causes: If you have medical conditions that can trigger hyperkeratosis, follow your doctor's recommendations and get treated.
- Good nutrition: A proper diet rich in vitamins and minerals contributes to healthy skin. Make sure your diet includes adequate amounts of vitamins A and E, which are beneficial for skin health.
- Stresscontrol: Stress can have a negative impact on your skin. Try relaxation and stress management techniques to reduce its effects on your skin.
Following these tips will help you maintain healthy skin.
Forecast
The prognosis of hyperkeratosis depends on many factors, including the type, location and severity of the condition, as well as how quickly treatment is started. In most cases, hyperkeratosis can be successfully controlled and the skin condition can be improved. The prognosis may be as follows:
- Mild Hyperkeratosis: If hyperkeratosis is in its initial stages and is not accompanied by pain or complications, a full recovery can be expected with proper care and treatment.
- Moderate hyperkeratosis: In the case of more severe coarsening and callosities, hyperkeratosis may require longer and more intensive treatment. However, with the right approach and regular care, a significant improvement in skin condition can be achieved.
- Severe hyperkeratosis: If hyperkeratosis has been ignored for a long time and is accompanied by complications such as cracks, infections or inflammation, treatment may be more difficult and time-consuming. However, even in these cases, with a doctor's involvement and adherence to skin care recommendations, improvement can be achieved.
- OngoingCare: It is important to realize that hyperkeratosis, especially if it is caused by external factors, may require ongoing care and prevention to prevent recurrence.
In any case, if hyperkeratosis is present, it is important to see a doctor or dermatologist to get a professional diagnosis and prescribe the best treatment method. Following your doctor's recommendations and proper skin care will help improve your skin's prognosis and condition.
