Keratosis pilaris, or keratosis pilaris, is a chronic dermatological disorder characterized by impaired keratinization of hair follicles, which manifests as small, granular, reddish or whitish bumps on the skin, most often on the upper arms, thighs and buttocks. This disease can vary in severity and cause various aesthetic and, in some cases, psychosocial problems in patients, especially in adolescence and young adulthood. Although keratosis pilaris is not infectious and does not cause physical discomfort, it requires attention due to the possible consequences for the patient's quality of life.
History of the disease and interesting historical facts
The history of keratosis pilaris goes back to ancient times, when many dermatological diseases were poorly understood and often confused with other pathological conditions. The disease was first described in medical literature in the early 19th century. In 1841, dermatologist Daniel De Martin noted its clinical manifestations and typical locations. Since then, keratosis pilaris has been the subject of numerous studies, and its connection with certain hereditary factors has only been confirmed in recent decades. The disease has probably become more noticeable due to increased interest in the aesthetic aspects of the skin and the growing number of patients seeking help.
Epidemiology
The epidemiology of keratosis pilaris shows a high prevalence of the disease, especially among adolescents and young adults. The disease is estimated to affect 40-80% of the population, with more severe symptoms observed in individuals with dry skin and a tendency to allergic reactions. Keratosis pilaris is most clearly visible in children and adolescents, but it can persist into adulthood. A 2020 study found that 30% of patients with keratosis pilaris had lifelong symptoms with fluctuating severity.
Genetic predisposition
Keratosis pilaris has a strong genetic predisposition, as evidenced by familial cases. Females are more often affected than males, which may be due to hormonal changes that occur during puberty. Genetic studies have linked the disorder to variations in certain genes involved in keratinization, such as the FLG (filaggrin) gene and other genes involved in the keratin and keratinocyte pathways. Mutations in these genes often result in disruption of the normal process of epithelial differentiation and renewal, ultimately resulting in the formation of characteristic bumps on the skin.
Risk factors for the development of this disease
The risk of developing keratosis pilaris may be related to several factors, including:
- Heredity: Having a family history of the disease increases the likelihood of it developing in children.
- Skin type: People with dry or sensitive skin are especially prone to the disease.
- Age: the disease most often occurs in children and adolescents.
- Hormonal changes: Fluctuations in hormonal levels, such as during puberty, can contribute to skin problems.
- Seasonal changes: Symptoms may worsen during colder months when the skin becomes drier.
These risk factors highlight the need for special attention to individual aspects of the patient's health and lifestyle.
Diagnosis of this disease
Diagnosis of keratosis pilaris is based on the clinical picture of the disease and physical examination. The main symptoms include:
- Small, bumpy skin lesions, often with a reddish tint.
- Dryness and rough texture of the skin in the affected areas.
- Symptoms may be worse during winter or low humidity.
Laboratory tests are generally not needed to diagnose keratosis pilaris, but in rare cases a skin biopsy may be needed to rule out other conditions. Radiological tests are not usually used because this condition is purely superficial to the skin. It is important to differentiate other skin conditions such as eczema, psoriasis, and other forms of dermatitis to make an accurate diagnosis.
Treatment
Treatment for keratosis pilaris is usually aimed at relieving symptoms and improving the patient's quality of life. These include:
- General treatment: use of moisturizers and emollients to maintain the required level of skin hydration.
- Pharmacological treatment: use of topical retinoids (eg, taclotren, adapalene) to normalize the keratinization process.
- Surgical treatment: In rare cases, dermabrasion or laser treatment may be used to reduce the appearance of the condition.
- Other treatments include using chemical peels to improve the overall condition of the skin.
It is important that treatment is individualized and takes into account the severity of the disease as well as the needs of the patient.
List of medications used to treat this disease
Among the many medications recommended for the treatment of follicular keratosis, the following can be highlighted:
- Taclotren (tacrolimus)
- Adapalene (diferin)
- Moisturizing creams (eg with urea or ammonium lactate)
- Chemical peels (with acids such as salicylic or glycolic)
The choice of a specific drug depends on the individual characteristics of the patient and the severity of the disease.
Disease monitoring
Monitoring keratosis pilaris involves regular check-ups with a dermatologist to assess the effectiveness of treatment and the condition of the skin. Monitoring steps may include:
- Regular skin examinations to check for any deterioration or possible complications.
- Dynamic monitoring of the effectiveness of local drugs used.
- Discussion of skin care regimen, including use of moisturizers.
The prognosis of the disease is generally favorable, but patients should consider the possibility of relapse and the need for maintenance treatment. Complications are usually not observed, except for possible psychological discomfort due to the appearance of the skin.
Age-related features of the disease
Keratosis pilaris can occur in different age groups, but symptoms usually become more severe in younger people around puberty. In children, the condition is usually mild and may resolve spontaneously as they reach adulthood. In younger people, symptoms may persist and vary in severity depending on skin care and other factors such as climate and lifestyle.

Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov emphasizes: “It is important to remember that keratosis pilaris is a chronic condition that requires regular care. The best results can be achieved with daily moisturizers, as well as topical retinoids, which will help normalize the keratinization process. Do not forget about the importance of maintaining healthy skin, especially during the cold season, when it becomes drier. Try to avoid harsh soaps and scrubs, which can aggravate the condition of your skin. And most importantly, do not hesitate to seek medical help if you have doubts or are concerned about any symptoms.”
